[00:02] <llogan> xreal: why not just use -target instead of following that link? [00:02] <xreal> llogan: I've checked it in current source, it's still valid. [00:02] <xreal> llogan: also, I tried to combine it, doesn't work. wait [00:02] <xreal> http://pastie.org/9818794 => target instead of preset. [00:02] <llogan> where is the rest? [00:04] <xreal> llogan: that's some hours old. Wait. It said something about a missing format. [00:08] <xreal> llogan: http://pastie.org/9819149 [00:09] <llogan> mbrittsess: maybe something like colorlevels=rimax=0.5:gimax=0.5:bimax=0.5 [00:09] <xreal> llogan: The preset dvd can't write into mkv, I think. [00:10] <mbrittsess> llogan: I tried that one already, it didn't work [00:12] <llogan> then adjust the *imax values [00:12] <t4nk240> hello anyone [00:12] <t4nk240> that give a help on ffmpeg h265 [00:12] <t4nk240> please [00:13] <mbrittsess> llogan: I tried both 0.9 and 0.1 and it didn't work [00:13] <llogan> if you have photoshop, and you can get curves filter to do what you want then you can export the curves preset file and use it in the ffmpeg curves filter [00:14] <mbrittsess> I don't have photoshop [00:14] <t4nk240> no one [00:14] <llogan> then use gimp and interpolate the values [00:15] <mbrittsess> Maybe there's something wrong elsewhere in my cmdline and I'm not noticing it?

[00:33] <t4nk240> iff i put 1 line anyone will help me xrreal? [00:33] <xreal> t4nk240: no, but it's more polite to do so. [00:34] <justinX> dvir: is the resulted mp4 supposed to have variable framerate too, or be more normal, filling up with do-nothing frames or something? [00:34] <t4nk240> ok xreal so no one help in where what begin the irc is better, no you are by your one find..... [00:34] <mbrittsess> If you're having trouble catching the console output, you can type your command and then put "| clip" after it to put the output to the system clipboard [00:34] <mbrittsess> Then you can simply put that on pastebin [00:35] <xreal> or use this one: https://clbin.com/ [00:35] <llogan> mbrittsess: why not set the size in showwaves instead of using super2xsai? [00:36] <mbrittsess> I do set the size in showwaves. I set it at half of what I want the final size to be, because super2xsai doubles the resolution by necessity [00:36] <t4nk240> i will gooogle about it x265 will talk with me [00:36] <dvir> justinX: the result mp4 should mimic the GIF, by playing it as a video instead. This means that yes, it should fill in that time with do-nothing frames :) [00:37] <xreal> llogan: Do you understand my problem? [00:37] <dvir> justinX: a similar technique would be to extract the frames from the gif, let's say 10 frames with variable timings, and then for the required FPS, copy each frame FPS*time_for_frame, and then stitch them together into a video [00:37] <llogan> mbrittsess: what i mean is, why not just set it to your desired output frame size and not even use super2xsai [00:38] <dvir> of course, when creating a video and knowing all that you don't have to do it like that [00:38] <justinX> dvir: yeah while mp4 can do variable framerate I guess it is better to not do it that way. I assume you should have to put a parameter telling what the resulting files framerate will have then. [00:38] <llogan> xreal: no [00:38] <mbrittsess> Because I specifically wanted it to be smoothed with super2xsai, the output from showwaves is fairly pixellated and it looks a bit nicer this way [00:38] <llogan> ah [00:39] <dvir> justinX: the interesting thing is that the rest of the video has the correct frame rate [00:40] <dvir> justinX: just the first and last frame that are a bit messed up [00:40] <justinX> dvir: and yeah if you can't get it work in another way, I guess you can manually duplicating the frames and use these as input to ffmpeg instead. [00:40] <llogan> mbrittsess: where is the gray? it looks white to me [00:41] <mbrittsess> http://i.imgur.com/IuOYjq5.png [00:41] <mbrittsess> That's the output I'm getting [00:41] <justinX> dvir: yeah there is support for variable framerate and, animated gifs was added 2013 or something I think. [00:41] <mbrittsess> The background is a uniform (235,235,235) instead of (255,255,255) [00:41] <xreal> llogan: I want to transcode the incoming mpeg2ts stream to pal-dvd compatible and put it in MKV. [00:41] <dvir> justinX: I did that, the issue with that is that it is a 'stupid' conversion - if you have duplicate frames, ffmpeg isn't taking advantage of it and would create a huge video file, compared to the optimized way [00:42] <justinX> dvir: ah [00:42] <t4nk240> one question does the x265 suport flv? [00:43] <llogan> mbrittsess: i'm not getting the gray. tested both ffplay and ffmpeg output [00:43] <justinX> dvir: if the only the first and last frame is problematic, I guess you can somehow circumvent the problem by asking ffmpeg to stitch together 3 files... one with only yoru first frame, then the mp4 you have made, and then the last frame [00:43] <mbrittsess> Something else I tried, based on how I'd do it with image-editing stuff, was using: curves=all="0/0 0.4/0 0.6/1 1/1" [00:43] <mbrittsess> Hmmm [00:43] <dvir> justinX: so I will assume it's just a bug, even though seems to be a pretty big one. Unless the GIF conversion of FFmpeg is being completely not worked on [00:44] <mbrittsess> Let me try it with ffmpeg and see if the resulting video file is gray, or white [00:44] <justinX> dvir: an alternative is investigating the bug. may the source be with you :-) [00:44] <llogan> mbrittsess: ffmpeg -i input -filter_complex showwaves=320x180:p2p:1,negate -ss 5 -vframes 1 output.png [00:46] <vivan> >uniform (235,235,235) [00:46] <dvir> justinX: can't wait to dive in ;) thanks by the way! [00:46] <vivan> that sounds like tv range [00:47] <vivan> is black 16,16,16 instead of zeroes? [00:47] <mbrittsess> This may sound stupid, but do you want me to replace the token 'input' with some particular file, in order to test that? [00:47] <llogan> yes [00:48] <xreal> Does anyone remember tools like "DVD shrink"? They resized DVD-R9s very fast to DVD-R. How did it work? [00:48] <mbrittsess> vivan: You are exactly correct [00:48] <mbrittsess> I thought it might've been a TV color range issue until I saw showwaves was producing rgb24 output, so I assumed it was working on a normal computer, uh...range [00:49] <mbrittsess> I think "range" is not the right word, but I'm not sure what *is*, sorry [00:50] <xreal> Is it possible to switch to another bitrate between minutes 20 and 30? [00:51] <mbrittsess> llogan: I'm getting yellow text "Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)" [00:51] <mbrittsess> Sorry if there was some other obvious thing I need to replace, this is my first day using ffmpeg [00:52] <llogan> it's possible your -ss value is longer than the input duration. i only added that so the first frame wasn't used in case it was silent so it would be less boring [00:52] <mbrittsess> (It's pretty wonderful software, like ImageMagick for videos, I will be using it more in the future!) [00:53] <mbrittsess> Er...actually, that was my fault :P [00:54] <mbrittsess> Output file is (128,128,128) on top of pure white [00:55] <mbrittsess> Except for a few pixels where the two waveforms intersect, which are full-black [00:55] <llogan> maybe SDL/ffplay acts differently between Windows and Linux. not sure why it shows gray for you and white for me [00:56] <llogan> or you're using an outdated version with an old bug [00:56] <mbrittsess> Hmm...maybe the default video encoding can't accommodate the color extremes? [00:56] <mbrittsess> Either that or a new bug, I downloaded this a few hours ago [00:57] <llogan> i tested current git head [00:57] <mbrittsess> It says...it's mpeg1video in yuv420p, I guess that would do it [00:57] <mbrittsess> Let me see if I can coax it into an RGB format [00:58] <mbrittsess> Erm...although if you already know how to do that, I wouldn't mind saving the trip to the documentation :P [00:59] <xreal> Is it possible to switch to another bitrate between minutes 20 and 30? [01:09] <mbrittsess> llogan: I tried exporting video to an actual format in a different format, and it gave me pure-white [01:10] <mbrittsess> So I guess it was a final-encoding issue [01:10] <mbrittsess> Although I'm curious to know what kind of awful video format ffplay is using by default that can't handle the extreme ends of grayscale [01:12] <mbrittsess> Well, thanks for the help, everyone! [01:12] <mbrittsess> Have a good night [02:54] <xreal> Can I make ffmpeg a streaming server, which sends to tcp://localhost:2222, until a clients opens and acceses this stream? [02:57] <c_14> add ?listen [02:58] <c_14> tcp://localhost:2222?listen [03:00] <xreal> let me try [03:10] <xreal> hmm... I can't get the stream to work. Let me try other things. [03:17] <xreal> finally! [03:17] <xreal> thanks :) [04:17] <grepper> I know about the -vf fps technique for outputting a single frame at intervals (ie. fps=1/300 for every 5 minutes), but I'm wondering if there is to output a range of frames at intervals, like every 5 minutes output 300 frames. ? [04:18] <grepper> s/there is/there is a way/ [04:19] <grepper> the only way I've been able to do it is to seek from the beginning of the file for each range of frames, which is obviously slowish. [04:41] <radiator> hi gius. been looking for thiis everywhere. got a bunch of mov files, need to covert them to audio. whats options do i need in ffmpeg? [04:42] <radiator> like mp3 i guess [04:57] <datajerk> tried the docs and google, no luck. is there a way to blur out a section of a video? not by time (figured that out), but by x,y-x1,y1? thanks [04:58] <datajerk> trying to blur out passwords on demo videos [05:02] <grepper> I know about the -vf fps technique for outputting a single frame at intervals (ie. fps=1/300 for every 5 minutes), but I'm wondering if there is a way to output a range of frames at intervals, like every 5 minutes output 300 frames ? [05:02] <grepper> oops, sorry [05:12] <grepper> radiator: Something like: -vn -b:a 128000 -c:a mp3 -ar 44100 [05:18] <xreal_alt> Is there a fast way to fix "moov atom not found" only with ffmpeg ?

I've tried "afade=t=in:ss=0:d=5 [main]; [main] afade=t=out:ss=10:d=5" but it doesn't work as expected ( fadein first 5 then play normally 5 then fadeout last 5 [16:28] <coolusernameXX> Hello, I'm trying to use ffmpeg's HLS segmenter (full command here: http://pastebin.com/7aiHcfud ) but I can't get metadata to copy between input and output. Has anybody know how to copy metadata (language names etc) to output files? [16:29] <coolusernameXX> If I try to use ssegment ant write directly to .ts files metadata transfers, but with HLS it doesn't. [17:36] <johnboy> Hi I have an issue when I try to merge a mkv file, here's the mediainfo output : http://sebsauvage.net/paste/?c9d0e92401e49d46#fPGEY6Ok5ly0VSS6LXXEx6NLLpXvDB... is something wrong with my settings ? [17:38] <techtopia> best way is not to try and merge mkv in ffmpeg [17:38] <techtopia> either use mkvtoolnix [17:38] <techtopia> or with ffmpeg, encode to ts, concat as ts (merge), transcode to mkv [17:38] <techtopia> or [17:39] <techtopia> transcode mkv to ts in ffmpeg, then concat, then transcode back to mkv [17:41] <johnboy> I used mkvmerge techtopia [17:42] <johnboy> tried mediacoder too but it does the same mistake which is : it adds 10 seconds of black screen in the beginning of the video [17:43] <techtopia> are you appending and not adding [17:44] <techtopia> in mkvmerge if you hit add instead of append it adds all video and audio files to one file, instead of apending them one after the other [17:46] <johnboy> yes I know that but when I merge the mkv file with a ass subtitle it still does not make a proper file [17:46] <johnboy> so I tried without the .ass file and same results [17:46] <johnboy> I don't get why it adds 10 second of black screen in the beginning of my file [17:51] <techtopia> oh i see [17:51] <techtopia> you messed up your frame rate [17:52] <techtopia> Frame rate : 23.976 fps [17:52] <techtopia> Original frame rate : 23.810 fps [17:52] <techtopia> you should encode to the source fps which in this case is 23.810 so you should add to your encoding line before the output -r 23.810 [17:52] <techtopia> but your source video is probably bad [17:53] <techtopia> and was probably 23.976 to begin with [18:00] <johnboy> ok techtopia I'll try that thank you [18:58] <sectroyer> Hello. I have raw video with nv16 pixel format but when I try to play it with ffplay I get this error: [18:58] <sectroyer> Impossible to convert between the formats supported by the filter 'ffplay_buffer' and the filter 'auto-inserted scaler 0' [19:07] <llogan> it's listed in -pix_fmts but not as a supported input or output format. i don't know why though. [20:09] <sectroyer> llogan: is it a bug ? :) [20:10] <Fohlen> anyone knows a simple snippet to "make a song louder"? [20:11] <Fohlen> I effectively need to change the dB or similliar because my targeting device is really quiet [20:11] <llogan> sectroyer: i don't know [20:11] <sectroyer> llogan: okay, thanks :) [20:12] <Fohlen> oh got it, there's a simple -vol option [20:12] <Fohlen> :D [20:13] <llogan> Fohlen: the volume filter values make more sense to me [20:13] <llogan> http://ffmpeg.org/ffmpeg-filters.html#volume [20:25] <johnboy> techtopia, ok so I managed to get a proper file. Basically, forcing the FPS to the original FPS wasn't enough because the sound got also 10 seconds so I encoded the original sound in ogg and I muxed it with the encoded video file plus the sub [20:25] <johnboy> thanks a lot techtopia ;) [20:35] <Fohlen> llogan: thanks [00:00] --- Fri Jan 9 2015
