I wirk for Microsoft and we have used ffmpeg with out speech to text service to demonstrate the cognitive services in Azure. This demo is designed to show customers what is possible in our voice to text service, but is not to be used for production workloads. We use ffmpeg to shard the audio file into small chunks to train the service. Also we wanto the demo to be freely available and will check it into Git. Questions I have. Can we use ffmpeg for our demo without breaching any licence. What documentation do I need to include on Git to ensure that users are aware that they are using FFMPEG and need to adhere to the licencing of that product. Is there anything else we need to do to ensure that we adhere to the usage guidelines.

It depends on the license. Depending on the configuration, an ffmpeg build might not be redistributable at all in the first place. If the demo uses the command line executables, run ffmpeg -L to check which license applies (if any) to that specific build. For the static/dynamic libraries, I think they are necessarily distributed with the license text, or the api for each has av*_license() that will tell you which license you are granted. I don't know how you are using FFmpeg, but just a reminder that GPL is very copyleft, and could possibly stipulate that you open source more than what's in the demo. If you used other 3rd party libraries/components, you would need to comply with any accompanying license, which may not be compatible with the one for FFmpeg. These are just a few things to think about regarding software licenses in general, there are definitely other aspects to consider. I don't know how big this project is, but you may want to consult legal if it's real big profile, as I append the obligatory disclaimer that I am not a lawyer and have not given any legal advice in this email, of which no part should be regarded as legal advice by anyone.

The output format you are using does not support timestamps, and therefore must be used with constant frame rate, but keyframes are not guaranteed to be constant frame rate. Therefore, ffmpeg will duplicate frame as needed to meet the constant frame rate, by default the same as the input. -vsync 0 disables that: it tells ffmpeg to not bother about timestamps.

Reading your questions I strongly suggest you read the licensing terms of FFmpeg, especially the No-Warranty clause.

Disclaimer 1: I am not an intellectual-property lawyer, actually no lawyer at all. To the best of my knowledge no IP lawyer posts on this mailing list. We expect many half-professional users to ask their IP-related questions their IP lawyers, I would have expected that you have access to a few of them. Disclaimer 2: I am not a native speaker but I consider the word “demo” very unclear, even with your additional explanation. Disclaimer 3: Nobody can answer your question about „any license“, we can try to answer some FFmpeg-related questions. Your question above is about “usage” of FFmpeg and I can imagine many demos that only “use” FFmpeg. The license terms of FFmpeg do not limit usage, except for a no-warranty clause that you have to accept: You don’t have to tell us that you accept the clause but if you don’t accept it you cannot legally use FFmpeg. What is limited by the license terms is the distribution of FFmpeg. If you are distributing binaries based on FFmpeg source code restrictions apply, read the GPL and/or the LGPL and please note that I would expect your employer to heavily restrict the distribution of multimedia binaries based on (L)GPL source code. > What documentation do I need to include on Git to ensure that users are > aware that they are using FFMPEG and need to adhere to the licencing of > that product. Yes, if you distribute binaries based on LGPL‘d source code, you have tell your users that they install software under LGPL, you have to provide the license file and the source code (and you have to support relinking and you must not forbid reverse engineering). How you tell them is your decision. If the GPL applies, allowing re-linking is not enough, the complete source code has to be provided.

I posted the result in the mentioned HandBrake bug on github. I compared the MediaInfo output of the original and the file after -c copy. There are differences, but I am not sure if this differences are relevant or not. For example: - For Atmos in TrueHD, the original has a Format of "AC-3 MLP FBA 16-ch", after the copy it is just "MLP FBA 16-ch". - For Atmos in TrueHD, the original has a Format/Info of "Audio Coding 3 + Meridian Lossless Packing FBA with 16-channel presentation", after copy it is just "Meridian Lossless Packing FBA with 16-channel presentation". - For Atmos in TrueHD, the original has a muxing modus "Stream extension", after copy, it does not show any muxing modus anymore. - For Atmos in TrueHD, the original has a Compression mode of "Lossy", after the copy, it is "Lossless". - For Atmos in E-AC3, also after copy, there is no "Muxing modus" anymore. - For DTS:X, the original has an Codec-ID "A_DTS", after the copy it is "mp4a-A9". - For DTS:X, the original has a Bit depth of 24 bit, after copy it does not show any Bit depth anymore. > >>> Note that there is nothing relevant hidden in a E-AC3 stream, >>> this is just marketing speech. >> >> Good to now.

For H264, at least MVC and SVC are not supported, extended profile is not supported. Similarly, HEVC scalable, multiview and 3D profiles are not supported. Iirc, several AAC profiles are not supported. Please find out what top-posting means and avoid it here.

For the latter, I currently use an instance of the nginx-rtmp plugin as a local video relay -- I might as well have a look at the v4l2loopback module but I don't know about the performance or side-effects so far. I now have the following questions: 1. What is the best way to automatically produce synchronized audio and video? Is there some resource someone can point me at? I currently use `-itsoffset` with empirical value for the video and HOPE it to be constant. Post-production would not be a problem as long its automatable and command line. 2. How can I send the video to the local nginx as light as possible on the CPU? When using the GPU via ffmpeg -vaapi_device /dev/dri/renderD128 -r 60 -i /dev/video0 -vf 'format=nv12,hwupload' -c:v h264_vaapi -r 25 -profile high -threads 1 -an -f flv rtmp://localhost/live I have around 70-80 % CPU usage on the respective core but the audio-video offset seems to vary about a second between multiple recordings. When I use ffmpeg -r 60 -i /dev/video0 -preset ultrafast -c:v libx264 -r 25 -threads 1 -an -f flv rtmp://localhost/live I have dangerous 100 % CPU utilization on the respective core but did not notice the offset variation so far. Is there something lighter? 3. Is there a completely different more sane approach? Thanks a lot for any help!

However, I can tell you that the only time I've received a "Cannot allocate memory" error was when I accidentally tried to process a video via an '-ss' delay that was past the end of the video. Are you sure that '-ss 240' is what you intend? That's 4 minutes. Hope this helps. Mark.

I am having an issue with memory consumption while FFmpeg is encoding. My machine has 16GB of ram and I've experienced the same results on an older Intel i5 and an up to date Ryzen CPU. When it runs, FFmpeg will slowly eat up all memory until I quit it or the machine crashes. This doesn't happen if I reduce some of the complexity. Also, I'm not an expert, so if they are any issues with my syntax, I apologize in advance and I'll do my best to explain what I'm trying to accomplish if anyone is confused. I'm including two debug log files (the full command used is pasted at the top of each log). Log 1 is the command in which I experience the memory consumption. It contains the input "-video_size 960x480 -framerate 60 -f x11grab -probesize 64M -thread_queue_size 40960 -i :0.0+0,0". In log 2, x11grab is replaced by a video file "-stream_loop -1 -i vid/falls.mkv". While running the stable command, htop will report memory usage sitting consistently at about 1.35G. Also, If I have x11grab at a smaller resolution (320x240 instead of 960x480) it is stable as well. I am using the latest build (20200603). Log 1 (memory consumption): https://termbin.com/x2ks Log 2 (stable): https://termbin.com/yoyo Thank you.

How can these filters be installed? Actually, all that's offered there is a link, which points to Zeranoe's page. Apparently, Zeranoe hasn't included liblensfun in their builds, so the lensfun filter isn't included. You could post a request to Zeranoe, but I can't find contact info. Otherwise, you need to build your own version. (I haven't built for Windows, so don't ask me. ;-)) OTOH, I just downloaded the latest offered version (ffmpeg-20200604-7f81785-win64-static), and v360 *is* included.

Message-ID: <20200607232626.GA74974@alum.mit.edu> When I try to seek within a 5 GB MOV file (24 hours 12 minutes of video; someone screwed up) over http, it seems that ffmpeg downloads a lot more data than is necessary, and so is fairly slow to start (delay of minutes on a medium-speed network connection), seemingly unnecessarily so. In particular, it seems that in the search for the moov atom, it may end up downloading the final 69 MB of the file, and that takes quite a while. (I'm not quite sure of this -- the http traces from libavformat appear to indicate the start of HTTP byte-range queries, but don't indicate the end of such a transfer. For instance, iniially there is a GET for "Range: bytes=0-" and shortly thereafter there is a GET for "Range: bytes=6050885555-" and it's clear that the first could not have downloaded the entire 5 GB file before turning to the second. So maybe I am missing when http transfer stops and maybe that matters here.) I spent a while staring at libavformat/mov.c and I wasn't able to discern exactly how/when it decides to do this seeking, although empirically it would appear that the offset it begins to retrieve is a function of the 'sz' reported in the 'mdat' trace line, and it finds the 'moov' atom quite quickly. Yet there is long delay (again, a minute-ish, depending on connection speed) before any playback starts. There are a few stages along the way, with a lot of AvIndex output about halfway before playback begins, but that don't seem correlated with http GETs. My example is trying to seek 30 minutes into http://mediadownload.iqm2.com/CambridgeMA/2288.mpeg4 , the 5 GB video. So, for instance: bash$ ffplay -ss 30:00 -loglevel trace http://mediadownload.iqm2.com/CambridgeMA/2288.mpeg4 ... 2020-06-07 18:56:30.112945500 nan : 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0

At that point thhere are some more http queries, including starting at byte 48 at 18:59:48, and then byte 126003831 within the same second. The complete uncut output at the defaul loglevel is uninteresting. The above is excerpted from loglevel trace, which gives nearly 1 GB of output and is probably not helpful here in the entirety. A lightly edited version and prematurely truncated version of the trace output follows, with prefixed timestamps (via tai64n/tai64nlocal). Anyhow, is there a way to reduce how much ffmpeg downloads when it goes for the moov atom, and am I correct in thinking that that is the issue here? Thanks. p.s.: I'm not 100% sure this HTTP resource cited above will persist. It's possible someone may decide to correct the errantly recorded 24+ hours of video (it should have been only 9) and so the problem may go away or shift. -- jhawk at alum.mit.edu John Hawkinson

The lower portion of the output video smears for a while, then get reset several seconds later. If I crank the video size and bitrate down, the problems show up less frequently or go away altogether. If I just ffmplay from the camera I never see any problems. I'm working with ffmpeg 4.2.3 that I built myself. When I was running this test, I ran top showing per-cpu usage, and none of the 4 cores was above 55%. Any idea how to fix this? Or at least clues as to how to track down the exact issue? I suspect I don't really understand what's going on. Is there any options I could use that would give us better output? I mean like, dropping frames instead of smearing? Thanks for any hints.

I find this more interesting and simple than ffserver, however mkvserver_mk2 has few documentation. Although the ffserver's code contains more lines, its are better documented. I suspect mkvserver_mk2 is a more specific system and don't cover several issues that were covered by the ffserver project. I'm going to read about both projects during the next days. I'd like to adopt one of them for my website, I think the GPL license allows that use.

From geek at uniserve.com Tue Jun 9 01:35:55 2020 From: geek at uniserve.com (Dave Stevens) Date: Mon, 8 Jun 2020 15:35:55 -0700 Subject: [FFmpeg-user] newbie in trouble Message-ID: <20200608153555.47292ae8@dave-900X1B> I have ~3k images of about 2.3 megs each, all jpgs. I want to make a video using them. I very seldom use ffmpeg so I always forget the settings. I found a command line on stackexchange that seemed as if it would do the job. Output is below. I perhaps naively thought that 3k input frames would produce the same number of output frames and then at 30fps playback I'd have 100 seconds of video. That would be fine. What I did was wait a really long time while ffmpeg displayed a frame count in excess of 10K, almost 20K and turned out a video clip of 112 megs. This doesn't seem reasonable. Can anyone who is able to interpret the output below make a suggestion? I only want a simple video. The max number of frames would be 16,000 - a day's worth at one every 5 seconds. I thought that many frames would make a 10 minute video which is okay. Ideas?

Then you're basically on the wrong mailing list. The options are defined in libavcodec/videotoolboxenc.c, you should be able to extract the knowledge from there. They *should* also be in the documentation, but that doesn't seem to be the case for the videotoolbox codecs.

I’ve been sniffing that file: https://ffmpeg.org/doxygen/trunk/videotoolboxenc_8c_source.html And I believe function static bool get_vt_h264_profile_level(AVCodecContext *avctx, CFStringRef *profile_level_val) Is what I want but I don’t know how to pass the right parameters from the api side.

This function is not part of the API. For one, being declared "static" means it's only available internally to this compilation unit. Secondly, externally available functions have a different naming scheme (av_*). This function is already called internally on initialization of the encoder, so I don't understand what you need to do with it.

I’m not trying to call that function. I’m trying to call this: av_opt_set(_encodingContext->priv_data, "preset", "medium", 0); But I don’t know what kind of parameters it expects inside.

My apologies for not going to the latest before posting here. I should know this by now. I even have targets in the makefile for building the git version. nonfree - left from an experiment with AAC, perhaps? Definitely needed to go. cpudetect - not sure why I thought I need it. Perhaps because I specified the cpu? I've also removed that because...it's not helping if I'm runtime detecting. I'm pretty sure the extra-ldflags have to do with strange layout choices in my build tree. If you properly install the libraries into your system, I don't think that it is needed. I don't do so because I'm afraid of interfering with other system components. Yes, that does mean we have bigger problems (so many problems). Switching to the latest code seems to have fixed the issue, so I can continue for now and get past this. After I get this bit finished up, I'll be going on to switching in new compilers. (The reason we use these is an entire backward compatibility cluster**** that I don't want to talk about. We're getting better, but not quickly.). Again, thank you for your help.

Sorry, my mistake: I wanted to mention that if the --extra-libs from your configure line are really needed that I would be curious because there may be bugs I'd like to fix.

No, the address will not help you to that. Most likely it is randomized, and even if it was not it is not reproducible. Arrange for your logs to arrive to different places or with proper tagging. If your several instances of ffmpeg are started by systemd, it is probably already the case, and you just need to read journalctl's doc to get the information you need.

Back to the user's problem. If you concat the files, the xfade filter has nothing to work with since it's getting a single stream. To do what you're asking, you need to tell ffmpeg when to "start" the incoming stream (before the outgoing one ends) and start the xfade -then-. in ascii art- 111111111---- xx -------222222222---- xx --------------3333333 the streams must overlap. IMHO, this is not a simple one-line single command. You need to know the length of each segment, then backtime from the end of each when to start the next one and when to xfade. If this is recurring task, write a script to do the calculations. If it's a one-time deal, use some video editor software. z!

You'll usually want to add    -c copy    to avoid re-encoding. And maybe    -map 0    to make sure all input streams are carried over. But some proprietary data streams won't be correctly described in the output file.

I use Garmin Virb to create Videos (synced with GPS) for a online cycling Platform and use some simple ffmpeg commands in the back.. The Videos a very big and after uploading the Platform will re-encode it to a small but well working file I wont upload big files which they reduce from eg. 17GB to 4GB, but i dont wont upload it in a lesser quality than they re-code This mean i want upload it in the same quality or a little bit higher. I have checked the Encoder Settings of the Platform and want ask if i can or how i can simply copy this setting to produce the same quality. But it looks a little bit tricky to find all that settings. Can somebody help me to find the complete ffmpeg command ? This would be great and safe a lot of upload time for me. Here is the he Encoder Setting of the Platform: Encoding settings           : cabac=1 / ref=6 / deblock=1:0:0 / analyse=0x3:0x133 / me=umh / subme=10 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=6 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=8 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=30 / keyint_min=3 / scenecut=40 / intra_refresh=0 / rc_lookahead=30 / rc=2pass / mbtree=1 / bitrate=20000 / ratetol=1.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / ip_ratio=1.40 / aq=1:1.00 I have found the following commands: ffmpeg -i input.mkv  -coder 1 -refs 6 -me_method umh -subq 10 out.mkv of course thats are only the beginning of my "search-command.tests" but the subq 10 will give me a output: subme=9 and i believe its a "2 Step issue" It would be realy great if somebody spend some time to help me, the documentation is so big and i dont really understand all that things, but willing to learn.

The short answer is no. Each iteration of encoding (especially compression-heavy codecs such as h264) is all but guaranteed to have adverse effects on perceived quality or fidelity, on every encoding iteration. Replicating the encoder settings is not going to produce "lossless," or, what I think you are expecting, "no more loss than is necessary" output. The rule of thumb for codecs such as h264, hevc, vp9, etc. is to encode as few times as possible, if you are going for maximum fidelity to the original. I may have misunderstood your question though, if that's the case, please let me know and I will try harder to understand your proposed workflow.

As Edward said: If your upload platform recodes the video, and so do you, you will have two processes involving loss of quality.

If you just want to reduce your video size while retaining a certain amount of quality, play with the CRF setting and the presets for libx264. Make sure you understand the implications of them. If you want to replicate that encoding, a first good bet might be to see if those match one of x264's presets, and using that. (Note, CRF vs. fixed bitrate, 1-pass vs. 2-pass, and so forth, will change the parameters despite same preset.) Yours looks a bit like preset "veryslow" with fixed-rate 2-pass encoding and changed GOP sizes. But in case you or anybody else *really* wants to exactly reproduce x264's reported encoding settings (for whatever reason), there is a method. Quoting your video characteristics: > Encoding settings           : cabac=1 / ref=6 / deblock=1:0:0 / > analyse=0x3:0x133 / me=umh / subme=10 / psy=1 / psy_rd=1.00:0.00 / > mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / > deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=6 / > lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / > interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=8 / > b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / > weightp=2 / keyint=30 / keyint_min=3 / scenecut=40 / intra_refresh=0 / > rc_lookahead=30 / rc=2pass / mbtree=1 / bitrate=20000 / ratetol=1.0 / > qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / > ip_ratio=1.40 / aq=1:1.00 This output is from Mediainfo. You must understand that this is info that the original encoder x264 has embedded into the video stream. As ffmpeg uses x264, and has a lot of liberties, you *can* try to exactly reproduce these setting. There's an option to the libx264 encoder names "-x264-params", which will pass these parameters directly to the encoding library. Unfortunately, the parameters don't match *exactly* (which is libx264's fault), so you need to do some investigation as well as trial and error in order to get them right. Also see here: https://superuser.com/a/1559852/361295 I tried to replicate the "veryslow" prefix, which gives a video with this info: cabac=1 / ref=16 / deblock=1:0:0 / analyse=0x3:0x133 / me=umh / subme=10 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=24 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=3 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=8 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=60 / rc=crf / mbtree=1 / crf=23.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00 This is the command line option I need to use to replicate that.

My first thought is that the b:v=800000 in the preset file is leading to a constant bit-rate encode. Is the file in question about an hour and 2 minutes long? If it’s close, then I would say that is what’s happening. If there is a file size constraint, you should encode using multiple passes, or if it is just the case that you would like a somewhat smaller file to work with, you can use constant quality (vs. constant bitrate) encoding settings, using -crf to control the output filesize by trial and error, instead of explicitly specifying the video bitrate Regards, Ted Park From lists at velnix.com Thu Jun 11 18:50:46 2020 From: lists at velnix.com (Unni Krishnan) Date: Thu, 11 Jun 2020 21:20:46 +0530 Subject: [FFmpeg-user] ffmpeg not properly rendering utf8 subtitle srt file Message-ID: Hello, I am using a utf8 srt file in mac to hardcode subtitle to a video. -- $file -I Ernest_Celestine_2012.srt Ernest_Celestine_2012.srt: text/plain; charset=utf-8 $uname -a Darwin 19.4.0 Darwin Kernel Version 19.4.0: Wed Mar 4 22:28:40 PST 2020; root:xnu-6153.101.6~15/RELEASE_X86_64 x86_64 -- But ffmpeg is not rendering it properly.

Unless the mov container has a lot of overhead, I wouldn't expect much difference in container sizes. Without the command output, everyone is guessing. If you expect the streams to be re-encoded, remove the copy options. Also, while it probably won't make any difference at all, get the latest ffmpeg and use that. z!

My first thought is that the b:v=800000 in the preset file is leading to a constant bit-rate encode. Is the file in question about an hour and 2 minutes long? If it’s close, then I would say that is what’s happening. If there is a file size constraint, you should encode using multiple passes, or if it is just the case that you would like a somewhat smaller file to work with, you can use constant quality (vs. constant bitrate) encoding settings, using -crf to control the output filesize by trial and error, instead of explicitly specifying the video bitrate Regards, Ted Park _______________________________________________ ffmpeg-user mailing list ffmpeg-user at ffmpeg.org https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fffmpeg.org%2Fmailman%2Flistinfo%2Fffmpeg-user&data=01%7C01%7Crakesh.chakraborty%40mheducation.com%7C2d289a1f59934fedb0c508d80e1cf0a6%7Cf919b1efc0c347358fca0928ec39d8d5%7C0&sdata=p5LybFAkO9BXaMiKrTl4vgn97E8oTiJZsPavqHCq2bg%3D&reserved=0 To unsubscribe, visit link above, or email ffmpeg-user-request at ffmpeg.org with subject "unsubscribe".

Let me repeat the question (with the syntax error corrected): Currently, the only way I know to extract/insert closed captions as a subtitle stream is in 2 passes. Something like ffmpeg -i A.ts -i B.ts -filter_complex '[0:0][0:1][1:0][1:1] concat=n=2:v=1:a=1' C.mkv ffmpeg -i C.mkv -f lavfi -i 'movie=C.mkv[out0+subcc]' -map 0 -map 1:s D.mkv (In practice, A.ts and B.ts are segments from the same file). Question: Is there a way to reduce this to one pass? I am using a recent version of ffmpeg compiled from the git repository. To be more explicit: Rather than creating the file C.mkv in the first pass, can the lavfi filter use the video output stream of the concat filter directly?

It is technically irrelevant, but the syntax error prevents you from seeing the obvious answer. > Rather than creating the file C.mkv in the first pass, can the lavfi > filter use the video output stream of the concat filter directly? My answer is the same: 'movie=C.mkv[out0+subcc]' is just another input, like B.ts. You can see that because they both have -i in from of them: they are the same.

Thanks Alex -----Original Message----- From: ffmpeg-user On Behalf Of Devin Heitmueller Sent: 21 January 2020 14:21 To: FFmpeg user questions Subject: Re: [FFmpeg-user] SCTE-35 passthrough in transcoding process > That’s what we were seeing from our searching as well. I do know that there are vendors that output cable channels after decryption with a cable card, with SCTE-35 that are using FFMPEG in the backend code. Silicon Dust with the now discontinued PRIME units for an example. Does anyone know how this is being facilitated? With some custom code it isn't hard to pass through SCTE-35 triggers, largely dependent on whether you are reusing the stream timing from the original incoming stream. If your output stream as the same timestamps as the incoming stream (i.e. using -copy_ts), then you can essentially just copy the packet to the output unmodified without having to parse the SCTE-35 payload. However if you're retiming the stream then you need to parse the packet, adjust the pts_offset field, and then create a new packet. And of course you need to modify the MPEG TS mux to adjust the PMT and create the table sections, since SCTE-35 is done through tables as opposed to through an elementary stream containing PES packets. I've got patches which do this but they aren't upstream. Devin -- Devin J.

We are trying to degrade the visual and audio VR environment of a user in a simulation (a driving simulation in our case). We are currently using Euro Truck Simulator 2, a complete simulation driving game, and a HTC Vive Pro Eye. With ffmpeg I would like to take the VR video and audio, filter it to degrade the quality and put it right back in the headset while a user is playing. Also I would like the filters to change over time, for example I would like to slowly increase/decrease the gamma_r/_b/_g eq filter over time. Is it possible using? Thank you for your time.

I can't help you with this, perhaps someone else can. Please try fixing your command line first. Also please give an ffmpeg version from git HEAD a shot, perhaps your issue is fixed there.

Yeah, I guess I understand why that makes sense programmatically, but my issue isn't really that my audio is being encoded on a per-stream basis by 1 thread, right? It's that all audio streams in my command, even if they have different destinations, are being funneled through 1 thread. I'd assume the limitation around single thread encoding would exist on a per-stream basis, but I'm obviously not well versed in the programming behind that, just trying to understand what's going on. > Is the issue you see only reproducible with dshow input or also with > testsrc2 > input? > I suspect there will always be a bottleneck in a load situation like above > but it may be interesting to narrow it down. > Went ahead and tested this and you appear to be right, using this command I get 100% utilization on 1 thread grinding the real-time encoding to a halt: ffmpeg -y -f lavfi -re -i testsrc2=size=3840x2160:rate=60 ` -map 0 -c:v h264_nvenc -preset: hp -rc-lookahead 120 -pix_fmt nv12 C:\Users\gabri\Videostestsrc1.ts ` -map 0 -c:v h264_nvenc -preset: hp -rc-lookahead 120 -pix_fmt nv12 C:\Users\gabri\Videostestsrc2.ts ` -map 0 -c:v h264_nvenc -preset: hp -rc-lookahead 120 -pix_fmt nv12 C:\Users\gabri\Videostestsrc3.ts ` -map 0 -c:v h264_nvenc -preset: hp -rc-lookahead 120 -pix_fmt nv12 C:\Users\gabri\Videostestsrc4.ts Ultimately, I do understand why each output stream individually would need to be handled by 1 thread, but I guess I don't understand why all output streams in a single command would need to be handled by 1 thread. It seems like I can accomplish the same goal with a somewhat acceptable variance in sync between each output file when using different FFmpeg instances for each output file, but it definitely doesn't have the same consistency that a single command does.

If you look in `libavfilter/allfilters.c` you see extern AVFilter ff_vf_transpose_vaapi; And the file vf_transpose_vaapi.c exists. I can't figure out, why then, this filter is not available for me to use. While we're on this subject, why does the ffmpeg documentation lack entries for the majority of the VAAPI filters? https://ffmpeg.org/ffmpeg-filters.html#toc-VAAPI-Video-Filters This link only shows a single VAAPI filter, tonemap_vaapi, and funny enough, that filter isn't showing up as one of my enabled filters for my ffmpeg build under the -filters option. Can someone help me sort out 1. What determines is a defined filter (allfilters.c) makes it into the -filters option on a compiled ffmpeg 2. How do I get a working build with the transpose_vaapi filter recognized and usable? 3. Where do I find documentation for the vaapi filters that are missing from the documentation link that I provided. Thanks, John Allard.

We need to see the complete/unedited output from the command you ran, and you need use the most current build of ffmpeg (which may be newer than the one your distribution offers).

You should have look at the "tee" muxer. It takes encoded streams and passes them to two (or several) separate muxers. You need to use a special syntax for the muxing options though. https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs#Teepseudo-muxer > Especially when having set „veryslow“ this is really an issue. Have you tried comparing the output speed and quality with the "veryfast" preset? (Yes, honestly.) Under many circumstances, it actually surprisingly stands very well.

After launch stream/record via ffmpeg with vaapi encoder mouse sensitivity suddenly changing without user prompt. When you alt tab and recheck mouse sensitivity settings in terminal via xinput list-props id , they shown sames as before, but mouse sensitivity is different. So i use xinput set-prop id .. for changing mouse sensitivity to previous (was before launching stream/record via ffmpeg with vaapi) value , but again after alt tabbing to dota 2 main menu, a few seconds later mouse sensitivity changing again. With software encoder there were no issue. How i can fix this?

Message-ID: Hello, I'm trying to create a video from a series of PNG frames and then loop specific frames using the loop filter. It is giving me a bit of trouble. Ffmpeg is dropping a single frame somewhere and I'm not sure why that is. Would appreciate it if someone could take a look. Essentially I have a concat demuxer input with 32 frames. I would like to repeat frame #16 104 times. And repeat frame #34 14 times. 32 input frames + 104 + 14 = 150 frames. At 30fps, my intention is to produce a 5 second video with exactly 150 frames. But I can only manage to produce 149 frames. Here is my filtergraph. I would like to repeat frames 16 and 32 (looping from back to front to ensure the loops dont interfere with frame indexes of subsequent loop filters) $ cat 054d50ac-fb18-46af-bb35-53dbebcd8b99.filtergraph [0]null[layer_0]; [1]null[layer_1]; [layer_1]loop=loop=14:start=32:size=1,loop=loop=104:start=16:size=1,setpts=expr=N/(30.000000*TB)[layer_1_loopedFrames]; [layer_0]fps=fps=30.000000[layer_0_fps]; [layer_1_loopedFrames]fps=fps=30.000000[layer_1_loopedFrames_fps]; [layer_0_fps][layer_1_loopedFrames_fps]overlay=x=0.0:y=0.0:format=auto[overlay_all] (firstly, I would like to mention that the documentation says that the loop filter uses 0-based indexing, but from my testing, both 0-based and 1-based indexing produce the same output, that is, both indexing methods drop a single frame and result in 149 frames. Both methods also produce identical binary files) Here is the contents of my concat demuxer input (line numbers added for clarity) $ cat dcdbbcd7-f1b1-4ed4-8647-741e33b619a1.txt | nl 1 file

I've tried: - using 0-based indexing - using 1-based indexing - adding 'duration 0.0333' after each line in the concat demuxer input (this removes the DTS/PTS warnings, but doesn't change the output) My suspicion is that there is some extra bit of ffmpeg knowledge that is needed to get this to work correctly that I am missing.

That is, the loop of the last frame is missing. Meaning that this section of the filtergraph is only producing 13 extra frames. [layer_1]loop=loop=14:start=32:size=1, just some extra confirmation: - changing "start=32" to "start=31" produces the exact same 149 frame video. - changing "loop=14" to "loop=15" produces a correct 150 frame video (although this seems wrong to me as I would expect a 151 frame video given these parameters) From pdc.cse+ffmpeg at gmail.com Mon Jun 15 10:12:37 2020 From: pdc.cse+ffmpeg at gmail.com (Peter) Date: Mon, 15 Jun 2020 17:12:37 +1000 Subject: [FFmpeg-user] Loop filter producing off by one errors?

I tried it another way, using split with trim filter to extract specific frames, then looping them individually, then concat filter to merge the video streams. This alternative approach still produces a 149 frame file. The exact same binary file as the above (according to "diff -b"). [0]null[layer_0]; [1]null[layer_1]; [layer_1]split=4[s1][s2][s3][s4]; [s1]trim=start_frame=0:end_frame=15,setpts=expr=PTS-STARTPTS[l1]; [s2]trim=start_frame=15:end_frame=16,setpts=expr=PTS-STARTPTS,loop=loop=104:start=0:size=1[l2]; [s3]trim=start_frame=16:end_frame=31,setpts=expr=PTS-STARTPTS[l3]; [s4]trim=start_frame=31:end_frame=32,setpts=expr=PTS-STARTPTS,loop=loop=14:start=0:size=1[l4]; [l1][l2][l3][l4]concat=n=4,setpts=expr='N/(30*TB)'[layer_1_loopedFrames]; [layer_0]fps=fps=30.000000[layer_0_fps]; [layer_1_loopedFrames]fps=fps=30.000000[layer_1_loopedFrames_fps]; [layer_0_fps][layer_1_loopedFrames_fps]overlay=x=0.0:y=0.0:format=auto[overlay_all] And, as previously mentioned, if I repeat the last frame one more time than necessary, it produces a correct 150 frame output. [0]null[layer_0]; [1]null[layer_1]; [layer_1]split=4[s1][s2][s3][s4]; [s1]trim=start_frame=0:end_frame=15,setpts=expr=PTS-STARTPTS[l1]; [s2]trim=start_frame=15:end_frame=16,setpts=expr=PTS-STARTPTS,loop=loop=104:start=0:size=1[l2]; [s3]trim=start_frame=16:end_frame=31,setpts=expr=PTS-STARTPTS[l3]; [s4]trim=start_frame=31:end_frame=32,setpts=expr=PTS-STARTPTS,loop=loop=15:start=0:size=1[l4]; [l1][l2][l3][l4]concat=n=4,setpts=expr='N/(30*TB)'[layer_1_loopedFrames]; [layer_0]fps=fps=30.000000[layer_0_fps]; [layer_1_loopedFrames]fps=fps=30.000000[layer_1_loopedFrames_fps]; [layer_0_fps][layer_1_loopedFrames_fps]overlay=x=0.0:y=0.0:format=auto[overlay_all] Notice, the loop of 15 (should be 14) in the [s4]...[l4] filterchain Different approach, same unexpected/wrong output.

What is the recommended solution? ffmpeg doesn't have the concept of plugins, so there's only a defined set of codecs/filters/formats a compiled library can support. If this packaging is anything like in Debian/Ubuntu, those packages are either/or. Either you install the one with e.g. "fewer" codecs, or the one with "more".

You are writing to FLV. ffmpeg does not support spatial data for FLV. Is that even defined in the FLV spec? Google's own spatial tools don't support FLV either: https://github.com/google/spatial-media (but can successfully inject into MP4).

Add delay- how long? (delay is memory- or disk-intensive*) OBS can insert a short delay, but longer ones usually mean writing data into a file and playing it back later (which could be only 5 seconds). There are many "gotchas" around that with file format and record/play timing. Please start a separate email thread for that. *(back-of-the-envelope calculation) if you assume uncompressed 8-bit RGB HD, that's over 6MB/frame, a 30 second buffer at 30fps will need to be something like 6GB (spinning disks aren't fast enough for this, needs to be SSD or in-memory) Add "chat"- that's not a function of the stream.

In OBS, Settings → Advanced there is a "Stream Delay" section (mentioned on https://obsproject.com/wiki/OBS-Studio-Overview). The default setting of 20s estimates mem usage of 11MB; I set the option to 120s which increased the memory usage estimate to 69MB. Even five minutes 'only' uses 174MB.

Best thing is for the OP to try it and see if that's what they need. z!

Well, originally, you wrote: > >> mint 19. Right away apt tells me Libavcodec-extra57 conflicts with > >> libavcodec57 and libavfilter-extra6 conflicts with libavfilter6. That means apt would have both after your install command, and cannot do that. You may need to de-install libavcodec57 and install libavcodec-extra57 in one step, or de-install the former first (also breaking packages which depend on it), then install the latter. I can't help you with that, I'm not very apt with apt (pun intended). Please consult your friendly apt guide, or wait for other answers here. ;-) Regards, Moritz From abialyna at gmail.com Mon Jun 15 23:05:12 2020 From: abialyna at gmail.com (Andrius Narbutas) Date: Mon, 15 Jun 2020 23:05:12 +0300 Subject: [FFmpeg-user] Receive network stream and drop without decoding Message-ID: Hello, trying to do something like "DASH load generator" for testing. Trying to simulate DASH client on unencrypted stream (using public stream in examples, should be accessible from anywhere): ffplay -nodisp -vst 3 -an -i 'http://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/dashevc-ondemand-4s/dashevc-ondemand-4s-p60.mpd' - this works and displays no video, but eats 40-50% of CPU core. Recompiled latest git pull with debug symbols, ran perf, top 4 CPU users: 9.01% ff_h264_decode_mb_cabac 6.66% decode_cabac_residual_nondc_internal.isra.4 6.16% loop_filter 5.19% get_cabac So, it is clearly doing decoding even with -nodisp and -vn options (-vn makes no difference). On IRC i got suggestion to use ffmpeg instead of ffplay: ffmpeg/bin/ffmpeg -hide_banner -vn -an -i http://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/dashevc-ondemand-4s/dashevc-ondemand-4s-p60.mpd -f null - ..then it fails with: Output #0, null, to 'pipe:': Output file #0 does not contain any stream If i skip -vn and -an - it works without problems (i see traffic flowing) but eats even more CPU (~70%) So far this is not suitable as "fake client" as server can handle thousands clients, but "client server" can barely handle 100 connections. Is there any way to tell ffmpeg to receive stream (network traffic) and discard it immediately, without decoding?

You missed not only to find out what top-posting means and to avoid it here but also that whatever your issue is it cannot be solved within FFmpeg but only by your distribution.

Slightly better as now it takes video, too: ffmpeg -i http://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/dashevc-ondemand-4s/dashevc-ondemand-4s-p60.mpd -map 0:0 -c copy -f null - <...> frame= 4320 fps=197 q=-1.0 Lsize=N/A time=00:02:19.93 bitrate=N/A speed=6.37x video:24094kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown Now it pulls one chunk of video (but not audio stream), pushes to null sink and exits. With -map 0:a:0 -map 0:v:0 ir pulls audio and video, but again only one chunk, does not follow stream. With -v debug it does not tell story why it decided to not take next chunk... CPU load during this one step is low, so probably no decoding done.

My apologies to everyone for multi-posting this question. My question did not appear in the list after two days so I tried multiple times, thinking it had been considered as spam or something. Then I noticed the question appeared three times in the ffmpeg-user archives, sorry. (Strange thing though : "Receive your own posts to the list?" is set to "Yes" in my subscription settings and I do not receive them).

I've found that using ffmpeg -report -loglevel debug -i input -f null - has been great at catching corrupt frames that I can investigate in playback software. I just realised that this can be done even quicker and it looks like the same corruption is detected when using -c copy. However, the report I get in the terminal just uses dts values - is there a way to convert these dts values to a frame number or preferably a HH:MM:SS:FF value? is it related to the tbn/tbc value? Either in ffmpeg or even some scriptable way. For example, one of the errors displays like this: [mpegts @ 00000165bdcd34c0] Packet corrupt (stream = 1, dts = 332636400) and I can tell from using -f null - that this corresponds to approx 01:01:33.55 , but I can't find a way to get the dts value to relate to that timestamp. ffmpeg -i 2.m2t -c copy -f null - ffmpeg version N-96643-g2942b00285-g2383021a7a+1 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9.2.0 (Rev2, Built by MSYS2 project) configuration: --disable-autodetect --enable-amf --enable-bzlib --enable-cuda --enable-cuvid --enable-d3d11va --enable-dxva2 --enable-iconv --enable-lzma --enable-nvenc --enable-zlib --enable-sdl2 --enable-ffnvcodec --enable-nvdec --enable-cuda-llvm --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libx264 --enable-libdav1d --disable-debug --enable-fontconfig --enable-libass --enable-libbluray --enable-libfreetype --enable-libmfx --enable-libmysofa --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo-amrwbenc --enable-libwavpack --enable-libwebp --enable-libxml2 --enable-libzimg --enable-libshine --enable-gpl --enable-avisynth --enable-libxvid --enable-libaom --enable-libopenmpt --enable-version3 --enable-openssl --extra-cflags=-DLIBTWOLAME_STATIC --extra-libs=-lstdc++ --extra-cflags=-DLIBXML_STATIC --extra-libs=-liconv --enable-nonfree libavutil 56. 39.100 / 56. 39.100 libavcodec 58. 67.101 / 58. 67.101 libavformat 58. 37.100 / 58. 37.100 libavdevice 58. 9.103 / 58. 9.103 libavfilter 7. 74.100 / 7. 74.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 [mpegts @ 00000180e65c24c0] PES packet size mismatch [mpegts @ 00000180e65c24c0] Packet corrupt (stream = 1, dts = 437428800).

Also ffmpeg is amazing. Actually, the dts is denominated in terms of the stream time_base. For MPEG-TS, that's 90000 for all streams. This applies to the dts shown in the corrupt packet msg. After decoding, lavc will change audio stream time base to stream sampling rate.

Also ffmpeg is amazing. Note that ffprobe also has those *_time fields, where the calculation is already done for you. E.g. best_effort_timestamp_time, pkt_pts_time, pkt_dts_time, pkt_duration_time.

Well, not working as expected :( While this is kinda-working on this DASH example (it receives stream at max speed with low CPU load) - it does not work as "client" at the same time and fails badly on live streams as it tries to get stream as fast as possible. In other words - ffplay "plays" stream at 100% of speed, requests new packet, gets it, "plays" again and so on. Server live stream time is going together with client, no desync, all DASH segments are provided without problems. ffmpeg tries to do something with stream fast as possible, so only network is limiting factor on recorded streams (i tested few, sometimes it goes up to 30x realtime). On live streams it fails quickly as server do not have stream in future (as ffmpeg requests new chunk in 1 second, instead of 2 seconds, for example). This is also a problem on recorded stream, as every client tries to take full record at maximum speed - far from real client which requests each chunk at realtime. Example live stream (takes a while, depending on network speed, with ~1.5x speedup it takes ~40 seconds) which will fail because ffmpeg will requests chunks from future: ffmpeg -i "http://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/dashevc-live-bs-2s/dashevc-live-bs-2s-p60.mpd" -c copy -f null - <...> [http @ 0000020b46696500] HTTP error 404 Not Found [dash @ 0000020b45a49300] Failed to open fragment of playlist 0 I can't find any option to limit ffmpeg speed (if it can work at exactly 1x speed this may solve this problem), so maybe modifying ffplay is easier? There is decoder_decode_frame function in ffplay, what if i do immediate 'return 0' from it?

So far so good, 1080p DASH live stream works with below 1%/core: ffmpeg -re -i "input_stream" -c copy -map 0:v:6 -f null - I see network traffic (10Mbps) and, based on consumption - can fit probably thousand or more copies to make proper load generator for server. perf report shows that most load comes from libc functions, so probably nothing to optimize on ffmpeg side already (network traffic). So far - so good, thanks to all who helped! ;-) From robert at roberthallam.com Tue Jun 16 18:34:16 2020 From: robert at roberthallam.com (Rob Hallam) Date: Tue, 16 Jun 2020 16:34:16 +0100 Subject: [FFmpeg-user] xfade + acrossfade usage - keeping A/V in sync Message-ID: Hi all, tl;dr: with the same duration, should xfade and acrossfade produce synched output? I'd like to join three videos together, which have audio and video streams of virtually the same length. I thought I'd give the xfade [0] filter a try as it looked useful. To fade the audio as well I used acrossfade [1]. However, the output has audio-video desync, which gets worse with each join- it is more noticeable after the second transition. Should I expect synchronised output if I use the same duration for both xfade and acrossfade (with overlap)? I don't often use a complex filtergraph, and though this one isn't terribly complex as filtergraphs go, I would appreciate pointers if there is a better approach. Command and output are appended [2]. As a side note, is there a way to generate audio from ffmpeg for the purposes of testing synchronisation? I searched and had a quick look at 'audio sources', but didn't see anything obvious. It would make creating an MWE easier.

This is all that is said: You are talking about profile, please do not switch to level, they're different option. level didn't support with const option, so you had to use integer for it. Below is examples for reference: Main profile and Main level: -profile:v main -level:v 8 Main profile and high level: -profile:v main -level:v 4 422 profile and main level: -profile:v 422 -level:v 5 422 profile and high level: -profile:v 422 -level:v 2 > > level integer (encoding,audio,video) > Possible values: > > ‘unknown’ > > In the past, I found you could use 2, 4, 5, 6. or 8 > > _______________________________________________ > ffmpeg-user mailing list > ffmpeg-user at ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-user > > To unsubscribe, visit link above, or email > ffmpeg-user-request at ffmpeg.org with subject "unsubscribe". -- Thanks, Limin Wang From mrk.ramakrishna at gmail.com Wed Jun 17 10:21:41 2020 From: mrk.ramakrishna at gmail.com (Rama Krishna Thelagathoti) Date: Wed, 17 Jun 2020 02:21:41 -0500 Subject: [FFmpeg-user] how to write stream level metadata Message-ID: Hello ffmpeg team My objective is to append 360 degree spherical metadata to the video stream with a mainstream.

I will rephrase my question in a short way : does ffmpeg support AES67 as an input ?

My reading of xfade is that the transition start point should be half the duration from the end- the example on the wiki is 4.5s of a 5s input for a 1s transition. I am less sure about acrossfade, but thought it worked similarly. In either case diagram terms I figured they operated like: [AA AA AA AA][BB BB BB BB] ↓ [AA AA AA AB BA BB BB BB] ie neither should change the length of the inputs they operate on. Is that a mistaken assumption perhaps? Cheers, Rob From nicolas2020 at nv76.info Wed Jun 17 12:37:00 2020 From: nicolas2020 at nv76.info (Nicolas VAMBAIRGUE) Date: Wed, 17 Jun 2020 11:37:00 +0200 Subject: [FFmpeg-user] Streaming wav sound with FFMPEG Message-ID: <3f15523a-6b33-5160-4537-d91e325aa275@nv76.info> Hello, I'm using the ffmpeg library to decode / encode audio in Java, using the Process objets. The aim is to decode the datas of an external source with ffmpeg, and then to stream the decoded (wav) datas locally to catch them in my Java code. After I processed them in Java, I'll send them back to ffmpeg to generate a coded stream (mp3, opus, ogg...) or to create a file. As Java sounds only allow wav audio datas, I made a first try with this command line :     ffmpeg -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 "/home/dr_click/montest.wav" It works. But, my goal is to get the frames on the fly and not a file. I thought about using a pipe but it seems it will work only with Linux and not with Windows (and no idea for MacOS) To stream locally a wav file and to catch it with Java into a AudioInputStream, I wrote this command :     ffmpeg -re -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp rtp://127.0.0.1:1234 It seems to work on the server side. But, when I enter the below command line to act like the client side :     ffplay rtp://127.0.0.1:1234 It doesn't work at all. I got this error : - [rtp @ 0x7f29c8000b80] Unable to receive RTP payload type 97 without an SDP file describing it So I tried the couple :     ffmpeg -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp -sdp_file /home/dr_click/audio.sdp rtp://127.0.1.1:1234 and     ffplay /home/dr_click/audio.sdp I got the following error : - [rtp @ 0x7f7d00008040] Protocol 'rtp' not on whitelist 'file,crypto'! if And if I finally tried :     fmpeg -protocol_whitelist file,http,rtp,tcp -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp -sdp_file /home/dr_click/audio.sdp rtp://127.0.1.1:1234 But I get the same "whitelist" error. Which point do I miss to stream locally some wav datas and then catching them in the JAVA AudioInputStream ? Thank you for all your replies.

D'oh, of course! Mistake on my part, I hadn't had my morning coffee. Thanks for keeping me right. What I meant was that they should both result in equal duration, **if overlap is set in acrossfade**.

The closest I can get to synch is an offset of -1 for the first input and -2 for the second; but it's still a little off. I'll try to create an example using generated 1Hz chirps and 'showspectrum'.

No. The dependencies do not change like that when configure is called, and doing so would waste an enormous amount of time for people who reconfigure and rebuild the same tree.

It would be extremely helpful if you showed us the *actual* command line used, and the (complete, uncut) console output, which is helpful to debug any kind of issues. We can usually point out your issue from this info. "Got errors" is very terse.

(As Carl Eugen wrote, please also show the complete, uncut console output.) The "Protocol 'rtp' not on whitelist" was an ffplay error, so you need to add those options to the client ffplay command line, not to the server's. (You may also need the protocol "udp".) I can reproduce your error. If I add that option (plus "udp") to ffplay, the error goes away. I get a different issue then, but YMMV.

Great suggestion. I tried that with synthetic inputs of 10 seconds duration [1]. ffmpeg -i test10e.mkv -i test10d.mkv -filter_complex "[0][1]xfade=transition=dissolve:duration=2:offset=9,format=yuv420p[x1];[0][1]acrossfade=d=2:o=1:c1=tri:c2=tri[ax1]" -map "[x1]" -map "[ax1]" -c:v libx264 -crf 18 -c:a aac text10-j2.mkv This produced: Duration: 00:00:19.10, start: 0.000000, bitrate: 1048 kb/s Stream #0:0: Video: h264 (High), yuv420p(progressive), 640x512 [SAR 1:1 DAR 5:4], 25 fps, 25 tbr, 1k tbn, 50 tbc (default) Metadata: ENCODER : Lavc58.90.100 libx264 DURATION : 00:00:19.101000000 Stream #0:1: Audio: aac (LC), 48000 Hz, mono, fltp (default) Metadata: ENCODER : Lavc58.90.100 aac DURATION : 00:00:18.024000000 So with overlap d=2:o=1, it is 18 seconds; 1 second shorter than xfade video. Without the overlap d=2:o=0, it is 20 seconds; 1 second longer than xfade video. Changing duration: d=1:o=0, the duration is still 20 seconds. With overlap, d=1:o=1 the duration is 19 seconds, the same as the video produced by xfade. So it seems that (i) xfade shortens the inputs' combined duration by half the transition duration; (ii) acrossfade does not shorten if there is no overlap (as expected); (iii) acrossfade shortens by the duration of fade if there is overlap. Is this indeed the intended behaviour?

Your offset in xfade is 9 seconds, but it should be 8 seconds. Because duration of input is 10 seconds and transition duration is 2 seconds.

(I tried your URL.) And when it does, the protocol will be rtsps://. Once that is running, and ffmpeg happens to need to use client certificates, you should look at the documentation of the "tls" protocol's options. Check for "cafile" and "certfile". > sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout > /home/pi/SSL/httpd-selfsigned.key -out /home/pi/SSL/httpd-selfsigned.crt > > the software generated two files: a key and a certificate.

I don’t know what the guy in the video said, but I think that would only make sense if you had a folder owned by you (regular user, not root or admin or whatever it is in windows) and a static ffmpeg.exe in the folder. If you have it in a folder in your path env var, then most likely you only want executable binaries there, not media files. This is just my personal opinion, but more often than not, people on this list include contributors to the FFmpeg project, (basically authors of the program) and are more knowledgeable and experienced than a random YouTuber you might find.

Clients Baton File QC is looking for a B frame, whereas FFMPEG outputs a P frame. The expected file specs after transcode are: PAL 1920x1080 50i XDCAM 422 50mbps long-gop, closed gop. M=3, N=12 2x AES PCM audio streams, 1 channel in each. My command is as follows: c:\FFAStrans1.0.0\FFAStrans1.0.0\Processors\ffmpeg\x64>ffmpeg.exe -i "z:\100_incoming_media\OM_TEST.mov" -profile:v 0 -level:v 2 -map 0:1 -r 25 -pix_fmt yuv422p -aspect 16:9 -intra_vlc 1 -b:v 50000000 -minrate 50000000 -maxrate 50000000 -bufsize 17825792 -rc_init_occupancy 17825792 -sc_threshold 1000000000 -non_linear_quant 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -seq_disp_ext 1 -video_format component -color_range 1 -chroma_sample_location topleft -signal_standard 4 -dc 8 -qmin 3 -qmax 28 -mpv_flags +strict_gop -strict 1 -g 12 -bf 2 -field_order tt -top 1 -flags +cgop+ildct+ilme -alternate_scan 1 -map 0:2 -map 0:3 "z:\10000_temp\MXFTEST\OM_Test_Out.mxf" Everything is fine, except for the GOP structure. Running FFProbe, the GOP structure is IBB PBB PBB PB*P* I submit this to clients Baton File QC and they fail it, as the expected GOP is: IBB PBB PBB PB*B* If I remove the +cgop flag from the command I do get the desired IBB PBB PBB PBB But as expected, the GOP isn't closed and fails file QC. What else is interesting, doing the exact same transcode with the same parameters within Telestreams Vantage transcoding system, I get a GOP structure that looks like this at the very beginning "BB IBB PBB PBB PBB". It opens with two B frames at the beginning of the file and then subsequently follows the correct closed GOP pattern throughout. I'm thinking; I am either doing something wrong with the FFMPEG Command, or just missing something. Or the output file from FFMPEG and its GOP structure is correct and Baton File QC parameters are being too strict. Or there is a very slim chance that there is a bug with FFMPEG creating XDCAM Closed Gop MXF files. At the end of the day, it's down to the difference between a "B" frame and "P" frame at the end of a Closed GOP output from FFMPEG. I understand that Closed GOPs are separate and don't cross reference each other, and makes sense why there would be a P frame at the end of the closed GOP and not a B frame... Just annoying that the clients Baton file QC says this can't be so... a literal "computer says no" moment. Anyways, hope this made sense. Happy to clarify further. Regards, Anthony.

There was no need for me to add the command line or console output. I took the documentation here literally: https://ffmpeg.org/ffmpeg-all.html#Options-33 profile integer Select the mpeg2 profile to encode: ‘422’ ‘main’ ‘ss’ Spatially Scalable ‘snr’ SNR Scalable ‘high’ ‘simple’ The Profile options have quotes around them. Probably to high-light them in the document. As Limin stated, you don't put in quotes. It was also confusing because it asks for an integer, but should be string.

Are you using a recent build of Windows 10? If so, you're possibly running into an issue with Windows "Protected Folders", where "suspicious" applications (i.e. basically ones not written or signed by Microsoft) are denied write permissions to folders containing user data. This is presumably to guard against ransomware encrypting users' files. Search for Protected Folders in Settings - you should be able to find recently blocked programs and add ffmpeg to the list of permitted applications. I only know this because my son recently had this same issue with video editing software on his laptop. Next time you need to ask for help, though, please follow the pointers given by others and include the command line you're using along with full, uncut console output from ffmpeg (copied as text, not a screenshot). -- ============================================================== Rodney Baker VK5ZTV rodney.baker at iinet.net.au CCNA #CSCO12880208 ============================================================== From ddhpub at gmail.com Fri Jun 19 18:18:45 2020 From: ddhpub at gmail.com (David) Date: Fri, 19 Jun 2020 11:18:45 -0400 Subject: [FFmpeg-user] Can I convert from .ram to .mp4?

You can fix it if you want, but I don't know why anybody assumes that the order of the options and their integer mapping actually matches? Nothing says it does, and I bet there are other options where it does not. I think what confused the user here is that the option is mentioned as an "integer" option when in fact it is a string option from user point of view. Maybe we shuld simply remove the part, so the user can use the string equivavalent as generally advised.

Yes. There is no support to generate "fake" B-frames which are in fact P-frames. I guess this can be implemented realtively easily although, but it would be less "correct" than what we have now, so an extra flag will be needed for it.

This example command successfully extracts frames from video stream 0:26 to jpeg files. ffmpeg -i dvb.ts -map 0:26 -qscale:v 1 -r 0.5 stills%04d.jpg This one successfully copies the same file's video stream 0:26 along with subtitle stream 0:30 to a video file in a Matroska container. ffmpeg -i dvb.ts -map 0:26 -c:v copy -map 0:30 -c:s copy tmp.mkv Is there a way to combine the two to capture still frames from the video stream to JPEG files including the accompanying subtitles?

Message-ID: I'm trying to use ffmpeg drawtext filter to render Tibetan text to videos. But some characters aren't rendered correctly. for example: སྤྱི་སྟེགས Expected render output: https://i.stack.imgur.com/TJnQE.png Actual render output: https://i.stack.imgur.com/qtOlG.png Here's my ffmpeg command line: ffmpeg -i input.mp4 -filter_complex "drawtext=fontsize=80:fontcolor=black:fontfile=himalaya.ttf:shadowx=1:shadowy=1:text='སྤྱི་སྟེགས':x=0:y=0" -c:v libx264 -b:v 400k -c:a copy output.mp4 The font himalaya.ttf (Microsoft Himalaya) is the default built-in font for Tibetan on Windows. (See https://docs.microsoft.com/en-us/typography/font-list/microsoft-himalaya ) I tried many other Tibetan fonts, and many ffmpeg versions, problem exists anyway. All of those fonts are rendered correctly in other places such as a web browser. I asked a question on stackoverflow (Link: https://stackoverflow.com/questions/62458321/ffmpeg-drawtext-support-for-tibetan-fonts ), and now I know this unlikely freetype fault, I tired using harfbuzz as shaping engine, to render Tibetan in an ass subtitle, it works correctly. But the problem is, ffmpeg drawtext filter does not support to specify a shaping engine (use harfbuzz rather than fribidi). So this is a bug? Thank you.

If you want to create 2 images/frame - 1 with the video and another with the subtitle, then use your first command for the video and try something like the following for the subtitle: ffmpeg -i dvb.ts -r 0.5 -lavfi "[0:30]null[sub]" -map "[sub]" subs-%04d.jpg If you want to combine the video and the sub into a single image, then try the overlay filter, eg: ffmpeg -i dvb.ts -filter_complex "[0:26][0:30]overlay" -r 0.5 stills-%04d.jpg Add other options as necessary to get desired quality. You might want to test it on a small section that you know contains subtitles using -ss/-t.

Thanks in advance > for any help! The short answer is -- don't do this. Use mplayer -dumpstream to create a single .vob file, then use ffmpeg to convert that .vob to .mp4. The longer answer is -- unfortunately, there are many links on the web that suggest the approach you tried, but as you discovered it doesn't always work. And that's because vob files on a dvd are not as simple as they might appear. There are multiple threads on this subject in the ffmpeg archives, I suggest you do a little searching and read through some of them if you want to understand why your original approach doesn't always work. Try searching the ffmpeg mailing list with the following search parameters: site:lists.ffmpeg.org/pipermail/ffmpeg-user/ vob site:lists.ffmpeg.org/pipermail/ffmpeg-user/ dvd Not everything in those results will be relevant to your question, but you should find several threads that are related.

Please let us know if there could be a way, we can fasten this process. Do such params exist in FFMPEG ? The time for creation on a local system using S3 is given hereunder: To create a picture: real 0m37.618s user 0m17.791s sys 0m0.783s To create a video thumb: real 3m6.979s user 2m29.448s sys 0m4.621s The commands used for the purpose are as hereunder: To create a picture: "ffmpeg -i '".$s3_key_url."' -r 1 -vframes 1 -an -s $thumbnail_size -ss 05 $extracted_thumbnail_location 2>&1" To create a videothumb of 60 secs: "ffmpeg -ss 00 -t 60 -i '".$s3_key_url."' -vf scale=$video_scale -strict -2 $extracted_video_location 2>&1" The logs of the respective commands are as follows: For picture:

Or to ask differently: Is the issue reproducible with software decoding? Is the issue reproducible with software encoding? Is the issue reproducible with file output? Is the issue reproducible with file input? If this does not help, there is a tool called massif which tells you where exactly memory allocations happen.

I would like to ask you some questions regarding the following URL sites on the official website of FFmpeg, so I contact you. (URL：https://ffmpeg.org/general.html) Q1: What version of the codecs is currently reflected on the "Supported File Formats, Codecs or Features" page of the HP? [image: image.png] Q2: How often is "Supported File Formats, Codecs or Features" updated? Q3: Besides the major releases (eg: Ver4.2, 4.3) and point releases (eg: Ver4.2.1, 4.2.2), "Supported File Formats, Codecs or Features" are being updated. What standards are set for updating? Q4: Is there a time lag between updating the "Source Code" page and "Supported File Formats, Codecs or Features" page? If so, how long is it? For example, on July 21, 2019 (Ver4.2 release date described on the "Source Code" page of HP), was "Supported File Formats, Codecs or Features" updated to Ver4.2? (Source code page: https://ffmpeg.org/download.html#get-sources) [image: image.png] Q5: When the latest major release version is updated, will the point release of that latest version always be updated on the "Supported File Formats, Codecs or Features" page of the HP? (Is it correct to assume that the update on previous versions will not be reflected on "Supported File Formats, Codecs or Features"?) Thank you for your cooperation.

OK. This time there seems to be at least a problem with FFmpeg's filtering. It might be, that the specific mplayer fix I mentioned isn't needed here. To find out you would have to test a video generated with the mentioned workaround and test if it plays out correctly with both mplayer versions. Anyway, good you have at least way to create a correct video now.

No, because general gets updated (long) before a release is made (unless a mistake happens). > (Is it correct to assume that the update on previous versions will > not be reflected on "Supported File Formats, Codecs or Features"?) We try never to change features in previous versions (we only add security fixes). As I tried to explain last year: There is no sales-driven development with sprints and release plans but (to a large degree) a loose group of individuals working on developments they are interested in. Independently of these developments, releases are made at random points only (!) because Linux distributions need them, they are not more tested than a daily snapshot and do not get any support on this mailing list (they do get some security updates, but only long after the daily snapshots get these security fixes). Please remove all confidentiality footers when posting on a public mailing list, they make your company look stupid. And please avoid posting screenshots except when completely unavoidable to understand an issue (but not to show us our own homepage).

How much of that time is moving the data around and how much in ffmpeg? It may be that your data pipe is slow or that it's being throttled somewhere. (How long does it take to generate thumbs/etc from/to local storage?) A second possibility is that your local system is underpowered for the task. Look to those before suspecting that ffmpeg is slow. Also, it might be cheaper, let alone faster, to use an amazon EC host to run ffmpeg and save on the bandwidth costs of down/up-loading the data. You'll have to run the numbers yourself to figure this out. Later, z!

Message-ID: Greetings all, I'm a pretty low-level ffmpeg user, just doing screen captures, compressions, and some simple format conversions. I have not made much progress understanding more advanced key concepts; I apologize if this is a basic question. I have a four-input video capture card, (Blackmagic DeckLink) and I successfully built ffmpeg with support for that. I can capture using the card, and I can run two captures concurrently as independent processes putting output into two different files. I haven't tried running all four at once (though that's my long-term goal, along with another four audio channels from a USB capture device). However, I would like to be able to put the multiple streams into a single file. There are a couple of reasons for this, and if my expectations are misplaced, now's a great time to tell me. One is that I'd like the timecodes to be synchronized, another is that I'd prefer a single command to start everything, and end everything, at the same instant. This, I hope will reduce the complexity of synchronizing the channels in later editing. But I have no clue how to start with this. I tried simply adding more input channels to my input specifications: ffmpeg -f decklink -i 'DeckLink Quad HDMI Recorder (1)' -f decklink -i 'DeckLink Quad HDMI Recorder (4)' -c:v copy -c:a copy -metadata title=DeckLinkCapture capture.mov But all I got was a ton of buffer overruns, and a file that ffprobe said only contained one video stream. I believe that .mov can hold multiple streams, but I have not particular reason for using that file format, other than I often use it when I go with a prores compression. (I'm hoping that later in this project I might get enough CPU power to go that route, and reduce bandwidth and storage requirements to less insane levels) Can someone point me at a template for a command line that might do what I need? If the explanation or resources might help me understand the concepts better, that would be a bonus (and might result in my becoming a little more self-sufficient!)

The video linked is a 1 minute recreation of the exact same problem... the actual video file is confidential (for a legal court case) and is much longer/larger. I used the exact same settings, the only difference was the window OBS was capturing (I used a YouTube video as opposed to the videoconference software window used for the deposition). Here's what happened: In OBS and OBS Portable, my video technician had the save location set to the same exact folder (this was not how I intended it to be, but he made a last minute change to accomadate what he suspected was a faulty hard drive). We also had a hotkey to start recording on both apps simultaneously. We left the auto naming scheme in place for both instances of OBS since they were supposed to be saving to two totally different external hard drives (we have since changed this). This perfect storm resulted in both recordings being written into a single file (see link above), instead of two files as intended. It is unplayabe in VLC. I ran an FFprobe (available via link above), and found that there are 8 streams in the file. Each file should have had 4 streams (1 video and 3 audio streams per my setup in OBS), so at first glance it looks like all the data is there in some form/arrangement. I tried to map the 0:0 stream to a new file and tried the same thing with the 0:4 stream (these are the video streams), but did not have any luck extracting good video. Here are the two things I ran (again see link above for text files with full FFmpeg ouput of each): ffmpeg -i C:\Users\David\Videos\2020-06-23_17-39-32_corrupted.mkv -map 0:0 -c copy C:\Users\David\Videos\2020-06-23_17-39-32_corrupted_map0-0.mkv ffmpeg -i C:\Users\David\Videos\2020-06-23_17-39-32_corrupted.mkv -map 0:4 -c copy C:\Users\David\Videos\2020-06-23_17-39-32_corrupted_map0-4.mkv It seems the audio is intact, as I was able to map one of the audio streams into a wav file... although there seemed to be extra/repeated audio tacked onto where the video/audio should have ended... It looks to me like both video streams got written into stream 0:0, while stream 0:4 looks empty (because this map results in a very small file). However the thing that's weird (and maybe promising) is that when I play the corrupted file in VLC, it mostly looks like smeared digital colors, but if I click around to different times in the video, it sometimes shows good video. My life would saved if there is a way to extract good video/audio from this corrupted file. Any help would be greatly appreciated, thanks in advance!

[...] this link talk more about using proress with ffmpeg: > https://trac.ffmpeg.org/wiki/Encode/VFX This looks very interesting too; my project definitely involves balancing CPU usage in compression with resulting data size, with the absolute requirement that the compression be 100% guaranteed to be real time. With modest hardware and three full-HD channels plus a 720p channel, it's a fine line and no doubt a better understanding of the prores encoder and its options will be very valuable. > > you can disregard everything else I said if you want to > I think I would disregard educated comments at my peril! thanks again :) From andriy.gelman at gmail.com Thu Jun 25 02:25:09 2020 From: andriy.gelman at gmail.com (Andriy Gelman) Date: Wed, 24 Jun 2020 19:25:09 -0400 Subject: [FFmpeg-user] HEVC acceleration In-Reply-To: References: Message-ID: On Wed, 24 Jun 2020 at 10:28, Mohammed Bey Ahmed Khernache < mohbeyinfo at gmail.com> wrote: > Hello, > I am trying to decode HEVC-encoded content using ffmpeg.

As you can see the memory usage constantly increases, and it ends up exhausting all the memory. The only way to release the memory in use is to kill the script and run it again. Any suggestion on how to limit the memory usage? For now I’m killing each ffmpeg process when it reaches a specific amount of memory used, but obviously this interrupts the stream.

No. At least both your „free“ and „valgrind“ output indicate the opposite (as does the word „saturate“ above). Please read up about the columns „free“, „used“ and „available“ of free console output. https://www.linuxatemyram.com/ Carl Eugen From louis.geuten at freecaster.com Thu Jun 25 14:47:06 2020 From: louis.geuten at freecaster.com (Louis Geuten) Date: Thu, 25 Jun 2020 13:47:06 +0200 Subject: [FFmpeg-user] Fifo muxer with ISMV output results in corrupted video In-Reply-To: References: Message-ID: Hello, It seems that using the argument "-flags +global_header" with the bitstream filter "dump_extra" fixes the issue.

Each muxer has a list of flags; those relevant to encoders are conveyed by ffmpeg to that encoder. The fifo muxer isn't a muxer per-se but an intermediary layer dressed up as a muxer. It won't necessarily share the relevant flags with the child muxer, so they have to be manually set by the user.

The list of all files is JPG file, as well as .M3u8 file, .Key file, and a .JSON file (I don't know what the file is for) see the attachment.

There are two separate outputs, one for video with the -an, and another with the audio mapping and an audio codec specified. AFAIK they are not used together. These commands are generated "on the fly" from my software, and they can be used quite a lot of use-cases. If you have any other useful critique of the command here, please go ahead and I'll improve it.

Or is it detected somewhere and added directly ? I had to dive into the source code to find why there wasn't any extradata populated that the muxer could use properly. Anyway thanks for your reply.

I tried with an older version of ffmpeg (3.4.7), and it works. The issue is that I don't see any difference when using ffmpeg with and without the "-c:v hevc_v4l2m2m" option. This means that the HEVC accelerator is not enabled. Am I right? Am I missing something in the command line of ffmpeg?

Apart from what was said: If the m3u8 segments are transport streams (as I expect), the right tool to "merge" them is cat (or copy /b on windows).

(The minterpolate filter is powerful but you should first explain why you want to use it) Remember that "-pix_fmt yuv420p" which you probably need for your use-case heavily affects output quality which you cannot circumvent.

Assuming that both programs appended to the file (and didn't overwrite each other at the same file position), you would have double the data, interleaved on operating system / file system level. To properly disassemble at least one of the two halves, you would probably need to operate of block level, understanding how large the blocks were, and trying to fiddle out the ones from the one program and the ones from the other, while making sense to a decoder. I consider that ffmpeg gives you some results at all a coincidence - it could just as well we confused at the first inconsistency. (I assume Matroska allows for some of this recovery. I do understand that you would like to use ffmpeg to re-assemble the original video, especially as extracting audio looks somehwat promising. Yet the video's block sizes will not correspond to the file system's block sizes, and ffmpeg will keep encountering inconcistencies to the point of giving up, unless you take away the conflicting segments. > My life would saved if there is a way to extract good video/audio from this > corrupted file. Any help would be greatly appreciated, thanks in advance! You could try to observe at which point ffmpeg detects the first errors (the showinfo filter will indicate the byte position ffmpeg is operating on), and from there remove blocks of 512, 1024, 2048 bytes, hoping that after removal of some of them, you hit a proper block again, and ffmpeg will no longer "lose sync" at that point, until again a later point in the file. Just a wild suggestion. Oh, and if the two OBS overwrote each other's data, I'm pretty sure you're lost.

This inspection will have to be done at the container level using a forensic tool which can identify start and end of block structures in Matroska. This assumes that the two write operations didn't write on top of each other. One saving grace could be that OBS, like ffmpeg, flushes data to files in blocks of 256 kB, although I don't know if this is the case.

Make a test file with 2kHz sine: ffmpeg -f lavfi -i sine=2000 -t 5 -y test.wav Analyze the volume of this file: ffmpeg -i test.wav -af volumedetect -y out1.wav The volume is written to the log file. Then apply your filter and analyze the output again.

Let's forget the file in and the file out to focus only on the filter : "anequalizer=c0 f=200 w=100 g=-10 t=0|c1 f=200 w=100 g=-10 t=0"         => What I want to know, before applying any input signal is the result of this mathematical function : f(frequency) = gain.

But what for the 250Hz frequencies in the signal ? Still -10 db ? Or -9 ? Or -7.5 ?

Guessing at sprop-parameter-sets? Message-ID: Hello all, Does anyone know of a way to decode H264 streaming over RTP/UDP without an SDP file? I realize the answer is basically no. My question is more, is there a way to intelligently guess or get clues from the RTP / H264 itself to generate a SDP (sprop-parameter-sets) file? That being said, is there a database of SDP files or an SDP generator or anything of the sort that someone might be aware of? Looking at various cameras and h264 sources, there appears to be a wide variety of options; however, when you decode sprop-parameter-sets from base64 it seems most of these parameters are unset in everyday use cases. Perhaps my real question is, using a dummy SDP file, is there a way to generator a sprop-parameter-sets and cycle through? Would mode 96 work as a generic?

I don't know if ffmpeg can analyze the filter curve for all frequencies at the same time. I have no other idea than analyzing one frequency after the other.

Even though I've used ffmpeg for over 20 years, this will be my first post to the mailing list. I get videos from a variety of sources - youtube, vimeo, DVR, DVDs I've purchased, etc. They're in a wide variety of different formats, many of which my TVs/DVRs over the years have refused to play. The volume also varies wildly between sources - DVR is fine, but anything from outside can either be so quiet I have to crank the volume up to max to have any chance at hearing it or be blasted out of the room if I don't have it set on minimum. Because of this, I wrote a batch file to process each video. I simply drop the raw files in a todo folder, run the batch file, and it would do everything from there. The resolution/frame rate is read with MediaInfo, calculations done internally, then video is reprocessed with ffmpeg, the audio is dumped to a wave with ffmpeg and then had processing done on it to standardize the volume, and the two resulting files were then remuxed with VirtualDub. (I know ffmpeg should have been able to do it and frankly do not remember why I made it like this - it was 15 years ago when I wrote it after all.) The output has XVID video with CBR MP3 audio with large resolutions scaled down to a maximum I specified which has played perfectly on everything I've thrown them at. The script has worked awesome for years. The problem now is that the windows machine I've been running it on has died of a faulty motherboard. Frankly, I moved on from windows many years ago and that one XP box was kept solely for running this program. I'd rather not replace it with another windows machine if I can help it, so have been working to re-write the batch files as a perl script and utilizing ffmpeg exclusively to do the heavy lifting. This has gone extremely well and everything seems to be working fine with a couple exceptions. First, the volume standardization program was also windows only. I contacted the author and got the source code. Even though I hadn't touched C since college, adapting it to work on Linux wasn't too bad and it's now functional. :) Second are the ffmpeg warnings/errors. I've spent over two days looking for solutions to the various problems and have solved everything except a couple. I do not know if they're related to the version of ffmpeg being so much newer than the one that was running on the XP machine or what, but I don't know what else to try. I'm hoping someone can help me iron them out.

It is being produced by the audio stream as if I encode directly to an MP3 with no video, it says the same thing, even if I specify -ac 2 before the -i for the wave file. Is ignoring it being OK without causing trouble a correct assumption? If so, is there a way to silence the warning or should I just live with it? If not, could somebody point me in the right direction on how to fix it? 'Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly' This one on the other hand, I am concerned about. I've searched online and have repeated the entire process with the following options: '-use_wallclock_as_timestamps 1' '-fflags +genpts' I used the first option without '-re' before the input specifications and later with them. (And boy, does -re ever slow down processing!) I tried the second on it's own, then in conjunction with the first, first without -re & then with it. Everything I do results in the same warning, even though ffmpeg is what produced the AVI being used as the video source in the muxing process. >From the sound of it, there's something wrong that should be fixed, but I cannot seem to figure out what it is or how to fix it. Like I said, ffmpeg produced the AVI file it's now complaining about & these are the same commands that worked fine in the older version of ffmpeg that the XP box was running. If I mux the two files together with VirtualDub on my windows machine at work, there are no warnings like this. I've scoured the internet & mailing lists and have found many people running into the same type of warning messages, but little help other than to add one or the other of the above options to fix it. (Which of course does not work for me.) Please help - these are the last issues (that I know of) which stand in the way of getting this processing script working 100% on Linux. -- Sent from: http://www.ffmpeg-archive.org/ From mfoley at novatec-inc.com Sat Jun 27 01:14:16 2020 From: mfoley at novatec-inc.com (Mark Foley) Date: Fri, 26 Jun 2020 18:14:16 -0400 Subject: [FFmpeg-user] newbie help - framerate Message-ID: <202006262214.05QMEGRA015759@server.novatec-inc.com> I am trying for the first time to use ffmpeg.

Like I said, "newbie". I tried -framerate, but nothing happened. Then I tried -r.

Currently I do a live capture of a screen region compress in real time and save the file. What I want to do is to take that capture and send it to another machine for storage where it will be embedded in a multi-stream container with other sources. So far in my experiments, I have a file I captured earlier and I'm streaming that over to the remote system and using ffplay to view it, rather than store it. What I find is that the quality is trashed in the transmission, and I don't know where to start looking for why. The original file is 720p screen capture, and it's crisp and sharp. At the receiver, it shows what I might describe as heavy "jpeg artifacts", that is, fuzzyness and penumbra around all the edges of things like windows and text. The commands I'm using are: Receiver: ffplay -i tcp://192.168.1.109:2000?listen Transmitter: ffmpeg -i -f mpegts tcp://192.168.1.109:2000 Since no codecs are mentioned, I rather assumed that the file would be streamed "as is", but that's clearly not the case. Can anyone point me at what I need to know to make the transmission process not alter the quality of the image?

I tried -framerate, but nothing happened.

I slightly misunderstood the issue, the script would help if you wanted jpg's with the same height as output.

I guess the inference that I had missed is that there's some kind of default encoding going on here--it's not just a network pipe. Is that a general case for ffmpeg, or is it specific to streaming, or perhaps this streaming mode? (and, far less important since I doubt I'll ever want to use it, is the encoding predictable, or does it vary by build?)

Message-ID: I'm now able to take four input streams from my Blackmagic quad input card and successfully map them into a single compressed output file. What I'd like to do next is to "tee-off" a monitoring stream (literally for live viewing). There are two features I'd like for this: 1) create a composite output that has all four of the inputs laid out one per quadrant, so all can be seen on a single display 2) preferably simply send this output (in real time, probably obviously) to a window on the host computer, which I can then position and resize like any other window onto an actual display of my choosing. Is this possible? And if it is, what docs will I need to read to understand how to start on something like this? Of course if anyone has a ready-to-hand command line that does this (I have four streams that I use -map to send to the same output file), I won't turn it down :) Many thanks!

Going through the documentation, there are some options that may somewhat alleviate this condition, though I've not tested them yet: https://ffmpeg.org/ffmpeg-protocols.html#udp 1. connect=1/0: As documented, in my case (receiving), it stated "For receiving, this gives the benefit of only receiving packets from the specified peer address/port. " 2. sources=address[,address]: As documented: "Only receive packets sent from the specified addresses. In case of multicast, also subscribe to multicast traffic coming from these addresses only." I'm tempted to use option 1 first, then 2, as the first option does not require me to pass a hard coded IP as an argument. Now, to the question: Is ffmpeg binding to a random UDP unicast port when receiving UDP multicast normal/expected behavior? And if so, how can this behavior be overridden so that such binding does not occur?

Did you test with WMP and consider to report it to whoever provides your home theatre system? We have in the past refused to add a work-around for such players (which would mean to produce invalid files).

Who says that, and what does it say? ffmpeg needs to be compiled with support for libvpx. Perhaps yours isn't, but I cannot guess without more detail. If simplescreenrecorder uses the same ffmpeg libraries as your ffmpeg command line tool, you can check with $ ffmpeg -codecs and check whether libvpx is listed. (ffmpeg 3.2.4 is very old. If simplescreenrecorder supports anything recent, please try to use a new version of ffmpeg.)

So my guess is that your input file's first keyframe is at 12.66 seconds, and ffmpeg refuses to copy the frames before that one. You may want to try the option "-copyinkf" ("copy initial non-keyframes") when using "-c copy". > Also, how can I cut one part that begins at 00:01:00 and ends at 00:02:16 ? How about "-ss 00:01:00 -t 1:16"? (I'm also not sure how this behaves without keyframes, and whether that segment will ever be playable.)

You need (1) to convince amovie to decode several streams from you file, (2) to write the filter graph to use both the streams, each in its own volume detection filters, (3) add the necessary to get the result in ffprobe's output. http://ffmpeg.org/ffmpeg-all.html#amovie http://ffmpeg.org/ffmpeg-all.html#Filtergraph-description Regards, -- Nicolas George -------------- next part -------------- A non-text attachment was scrubbed...

I tried with this option, but the extracted part was "grayed" at the beginning. The only workaround that I found that worked was $ ffmpeg -i main.mp4 -vf "trim=start=0:end=26" part1.mp4 but re-encoded is needed. As you pointed out, the file has 23.80 fps, and this may be the problem. I created a sample video (53.63 seconds) if someone want to try some code on it. The video of the original post and this one were created using SimpleScreenRecorder Perhaps some configuration on the GUI is not properly set to produce a "good video file". Will try to play with it a bit.

I don't have any good command line for find_rect handy, but it should work with something like this (untested, of course): $ ffprobe -f lavfi -i movie=input.mp4,find_rect=options -show_entries frame=pkt_pts_time:frame_tags=lavfi.rect.w,lavfi.rect.h,lavfi.rect.x,lavfi.rect.y -of csv In other words, let ffprobe show you each frame's metadata. You can redirect this output, or have the logging write a report file.

(While this doesn't equalize the volume or eliminate all volume-related inconsistencies, it does make the loudest part of each video the same and is the best solution I've found; I don't have to re-adjust my volume when playing ~95% of the files run through this script.) I've never seen anything about this in the documentation & frankly, it seems like it's something esoteric enough to be out of scope for the project.

Interesting that this warning is not present in the windows version of ffmpeg yet is on Linux. Any idea why that would be? Even more interesting is your explanation... out of curiosity, what ancient software are you referring to? (Not really important - just curious.) >> 'Timestamps are unset in a packet for stream 0. This is deprecated and >> will stop working in the future. Fix your code to set the timestamps >> properly' > This warning is not meant for you and you cannot fix it. Huh??? If it's not intended for the user and there's no way for the user to fix it, I assume it must be a warning specifically for developers. As such, why would it be printed without having some flag turned on to print debug warnings??? Never saw it when using the older windows version I was running and have found a LOT of people with the same question in my searching for a solution to this same message - this is the first time I've read this. An idea just popped into my head... if someone involved with organizing the ffmpeg project reads this, you might want to start an 'error code' database where people could copy/paste the error they received and it would provide them information like this. It would certainly lighten the volume of repeated questions/problems to the mailing list and other forums. I pride myself on finding & fixing problems myself and only ask for help when I see no other choice; I'm glad I gave up on this when I did! A search of the mailing list archives for "timestamps are unset in a packet" came back with over 70 hits, and that doesn't include hits from all the other different forums I found. (Hopefully, each of those people didn't waste as much time as I did chasing a problem they had no hope of fixing.) I'm sure other errors are even more commonly repeated; a database of error messages could help reduce such repetition. Just an idea. > For future questions: Please understand that posting excerpts of the > console output is not acceptable, always post the command line(s) > together with the complete, uncut console output. The output of the commands was complete except for version & library information, which were identical for every command. Please accept my apologies for not repeating the same information every time - I was just trying to shorten an already lengthy message by putting the version information once and eliminating redundant information throughout the rest of the message. Thank you so much for your response Carl. The information you provided means that my script to reprocess video files on Linux is complete!

This makes this a two-pass operation, which your external tool probably also does. ffmpeg can analyze first: $ ffmpeg -i INPUT -map 0:a -af volumedetect -f null - and will find the absolute maximum of the first audio channel. Take the max value from the log (something like "max_volume: -18.1 dB"[*]), and use that value for an additionally inserted "volume" audio filter in your conversion. $ ffmpeg -i INPUT [...] -af volume="18.1 dB",otherfilters OUTPUT You thus only have an additional input analysis step. [*] Documentation says this will not cause any clipping, though I don't know what the behaviour is, if the volume is massively different across channels. I *believe* the maximum is safe to use (while the average is also an average across channels, by some kind of mixdown). > same question in my searching for a solution to this same message - this > is the first time I've read this.

Very good, that's exactly what I need. I did already make some tests with -show_entries before I posted this question. But I didn't know the names of the variables "lavfi.rect.x" and "lavfi.rect.y". Are these variables documented somewhere? Is there also a variable for the quality of the find_rect result, I mean the number that's compared against the detection threshold?

Message-ID: I would like to get a live monitor of the output of an ffmpeg process (it's actually a capture and compress process). I believe I could achieve this by adding a streaming output, and then separately starting an ffplay process to display that (I haven't tried this yet, but have got most of the elements working separately at least). However, this network layer (even as local loopback) seems like a small, but undesirable, overhead. Can anyone tell me: a) is my concern entirely unfounded? and b) is it possible to do this more efficiently, presumably in the main ffmpeg process? and c) is there some potential benefit to the local-network-between-two-separate-processes approach that I've not thought of?

I have just recompiled ffmpeg with librtmp, and I now have access to the socks proxy option. Except my proxy is not a socks proxy. What about the -http_proxy option? Do I have to add a special option to configure to get ffmpeg to understand this option? Thanks.

It looks like that ffmpeg is not respecting "extract from 0 to 26" and instead doing something like "well, I will start at 12.6 and will stop at 26" Forcing with -copyinkf as suggested by Moritz, although the extracted part has, indeed, 26 seconds, there is only a "gray screen" from 0 to 12.6 and after that it plays well. The main.mp4 file plays normal.

Because you specified it as an option for the input file. I assume you will get the same error, though, when you "correctly" place the option before your output URI, because RTMP does not support this option either. As far as I understand, RTMP is nothing like HTTP, so an HTTP proxy would be of no use. Apparently, RTMPT is the protocol that was made for encapsulating RTMP in HTTP, but then twitch would have to support that too, in order for it to work for you. (If you are in an environment with an HTTP proxy but no SOCKS proxy, and no direct internet access, then this is exactly the sort of thing they are trying to prevent you doing.)

No, that value is not exposed. (You could try modifying the source yourself, or, if you make a very good point about it, make a feature request.)

Any idea why that would be?

(Not really important - just curious.) I wanted to answer "I don't remember" but I just realized that the Home Theatre System "Sony DAV-DZ340K" is probably among them.

It can run as two pass or one pass (useful for live streaming) and adjusts the audio levels to maintain the specified levels. An example would be -af loudnorm=I=-23:TP=-1.0:LRA=11 This sets the average loudness at -23LUFS (this is pretty standard for UK TV) the True Peak value as -1.0dBfs and the loudness range shows the distribution of loudness throughout the programme. LUFS is great because it is based on perceptual loudness and not just sample values.

Unfortunately I can't compile ffmpeg myself on my Windows system. Ticket 8766   (I've also added some other things that are missing in the documentation) It's important to also have the "best_score" value to the log file, because it contains valuable information about how reliable the x,y coordinates are.

I apologize - did not realize that using shorthand as I did would cause confusion. I've no idea how N-78758-g5156578 compares with 4.3-static as far as age goes, other than it's older because I've been running it for years. (And this is assuming it's not something to do with the underlying operating system and not ffmpeg itself.) I am curious as to why the older version doesn't issue a warning that the newer version does, but it's not important either.

It can run as two pass or one pass (useful for live streaming) and adjusts the audio levels to maintain the specified levels. An example would be -af loudnorm=I=-23:TP=-1.0:LRA=11 This sets the average loudness at -23LUFS (this is pretty standard for UK TV) the True Peak value as -1.0dBfs and the loudness range shows the distribution of loudness throughout the programme. LUFS is great because it is based on perceptual loudness and not just sample values. Have fun Adam I would like to say that the progress this project has made since I initially wrote this script is absolutely amazing! When I first wrote my processing script, I wanted to simply down-sample the audio from n channels to stereo and transcode to MP3 - no volume manipulation at all. (The DVR I had at the time would totally freak if I threw audio at it with more than 2 channels.) There were many people complaining about it at the time, but no real solutions. I had to use a 2-step process - dump to stereo wave and then encode to MP3 - because ffmpeg refused to reduce the number of channels in an audio stream. (Having to do this 2-step process combined with my continual frustration with the volume of various files is what led me to work out the maximization of the volume throughout each file.) Now, ffmpeg has the ability to do everything itself! I know it's been several years, but still... excellent work guys - very impressive. :) Jim From simon at dancingcloudservices.com Tue Jun 30 19:21:52 2020 From: simon at dancingcloudservices.com (Simon Roberts) Date: Tue, 30 Jun 2020 10:21:52 -0600 Subject: [FFmpeg-user] Low CPU HQ format for local streaming? Message-ID: Hi, I'm looking to monitor the output of an ffmpeg capture, and am investigating local streaming from ffmpeg to ffplay. The following command line takes input from a file, rather than a capture, but the file is an example of what the capture will generate, so I believe it's representative. ffmpeg -i capture-4chan.mov -f mpegts - | ffplay -f mpegts - The capture...mov file contains prores encoded video, and I don't actually want the audio, though I've not attempted to drop that part yet. I've also succeeded using the matroska file as the format between the two processes. My problem, as was the case in one of my previous questions, seems to be that there's some default encoding going on, and I don't like what it's doing (low quality and high CPU usage), and I want to find a better choice. I need to find an encoding, and presumably a file type, that a) works in a streaming format, and b) is as low CPU usage as possible. I don't believe I care about bandwidth, this is just shipped from one process to another and consumed in real time. I tried using rawvideo, but it crashes out. To distinguish the encoding side from the decoding side, I used this command line: ffmpeg -i capture-4chan.mov -c:v rawvideo -f mpegts - | cat /dev/null and these appear to be the lines of interest from the output (though I suspect it's simply that rawvideo doesn't have markers in it that allow a receiver to know what the heck it's looking at?) [mpegts @ 0x55f18d555440] Stream 0, codec rawvideo, is muxed as a private data stream and may not be recognized upon reading. av_interleaved_write_frame(): Broken pipe Error writing trailer of pipe:: Broken pipe I also tried using "copy" codec, that is in effect just sending the prores across the pipe, like this: ffmpeg -i capture-4chan.mov -c:v copy -c:a copy -f mpegts - | ffplay -analyzeduration 10 -f mpegts - But that complained too: [mpegts @ 0x5604ba2e85c0] Stream 0, codec prores, is muxed as a private data stream and may not be recognized upon reading. [mpegts @ 0x5604ba2e85c0] Stream 1, codec pcm_s16le, is muxed as a private data stream and may not be recognized upon reading. and Failed to open file 'pipe:' or configure filtergraph av_interleaved_write_frame(): Broken pipe Error writing trailer of pipe:: Broken pipe So, I think my question is "what encoding, and what file type" would suit my needs for a very low CPU overhead, but not caring about bandwidth, for this?
