[00:00:20 CEST] <dastan> With this one i get the speed of the process [00:00:20 CEST] <dastan> tail -f "log" | grep -o -E "speed=[0-9]+.[0-9]+++[a-z]+|speed=[0-9]+.[0-9]++[a-z]+|speed=[0-9]+.[0-9]+[a-z]+|speed=[0-9]+[a-z]+" [00:01:42 CEST] <dastan> With this one i get the file being opened at the moment [00:01:42 CEST] <dastan> tail -f "log" | grep -o -E "Opening '/home/build/MSS-ONE/temp/cache/TN-27153d00/TN[0-9]+.ts|TN[0-9]++.ts|TN[0-9]+++.ts' for writing" [00:01:52 CEST] <dastan> i need to show them together [00:06:47 CEST] <klaxa> you can simply combine those to: grep -o -E "(speed=[0-9]+.[0-9]+++[a-z]+|speed=[0-9]+.[0-9]++[a-z]+|speed=[0-9]+.[0-9]+[a-z]+|speed=[0-9]+[a-z]+|Opening '/home/build/MSS-ONE/temp/cache/TN-27153d00/TN[0-9]+.ts|TN[0-9]++.ts|TN[0-9]+++.ts' for writing)" or can you not? [00:12:56 CEST] <dastan> lets try [00:14:23 CEST] <dastan> its not in the same line but its a good improvement [00:14:53 CEST] <dastan> i get this speed=1.01x [00:14:53 CEST] <dastan> TN829.ts' for writing [00:15:47 CEST] <dastan> and i dea to show the info in two columns? [06:17:01 CEST] <mr_lou> Does ffmpeg have any fancy way of detecting and removing socalled flash frames? I.e. frame in the video overexposed due to flash photography. [06:28:14 CEST] <VikeStep> just wanted a quick sanity check, I've written a program that does the avcodec_send_packet/avcodec_receive_frame loop for every frame in a video. for a 1h20m 1080p h264 mp4 video at 30fps, it takes 4m32s to parse the entire video. Does that sound like a reasonable amount? Or would you expect it to be much faster? [06:37:02 CEST] <furq> VikeStep: time ffmpeg -i foo.mp4 -f null - [06:37:13 CEST] <furq> should at least give you something to compare it against [06:37:29 CEST] <VikeStep> ah, I've never actually used the ffmpeg tool before so forgot that existed [06:37:54 CEST] <VikeStep> will see how that goes [06:44:25 CEST] <VikeStep> it gives pretty much the exact same speed, cheers [07:54:37 CEST] <lain98> whats a good heuristic to check for vfr. i know vfrdet does this but i dont want to run a filter over the entire video [07:59:12 CEST] <furq> https://ffmpeg.org/doxygen/trunk/structAVPacket.html#a622e758be29fd500aed0ff... [07:59:15 CEST] <furq> probably that [08:00:02 CEST] <furq> ffprobe -show_packets if you're not using the spi [08:00:03 CEST] <furq> api [08:09:30 CEST] <lain98> furq: so AVPacket::duration [08:09:32 CEST] <lain98> will be unknown(0) ? [08:14:42 CEST] <furq> if it's cfr then it should be the same for every packet [08:15:21 CEST] <lain98> but that still means i have to iterate over packets :D [08:15:40 CEST] <furq> sure but you don't have to decode the video [08:15:40 CEST] <lain98> hmm [08:15:42 CEST] <lain98> yes thats true [08:15:42 CEST] <furq> you can also break early if it is vfr [08:16:51 CEST] <lain98> right now i just check avg_frame_rate.num==1 in stream [08:16:51 CEST] <lain98> thanks furq [08:17:43 CEST] <furq> there might be a better way, i've not used the api very much [08:26:35 CEST] <JEEB> lain98: if you really want to know there's no other way than indexing :P [08:26:40 CEST] <JEEB> you can try and attempt to hack around it [08:26:53 CEST] <JEEB> but you have asked a technical question and technically there is just one answer to it [08:26:59 CEST] <JEEB> I am sorry to bring it to you :P [08:32:04 CEST] <lain98> JEEB: looks like most of my problems could be solved by indexing [08:32:06 CEST] <lain98> :) [08:33:30 CEST] <JEEB> lain98: the best stuff of course is when you have a container with non-exact timestamps like MPEG-TS or FLV. then you also have to have logic (like ffms2 has I think) which looks at some difference to constant frame rate and sets the content as CFR if the timestamps seem to be just oscillating because of time base being inexact [08:34:09 CEST] <lain98> *mind blow* [08:34:47 CEST] <lain98> codecs and containers are as varied as animals in the jungle [08:53:56 CEST] <Mavrik> It is easier if you have a limited number of input options [08:58:10 CEST] <lain98> got me thinking if i have a list of some non-standard fps like 29.97 and stuff and then combine the check with or the fps is a whole number like 1/x where i just check the avg_frame_rate.num==1 [09:07:41 CEST] <lain98> i should be fine ? [13:27:52 CEST] <kepstin> note that 29.97 (actually exactly 30000/1001) is a standard fps [13:31:41 CEST] <lain98> okay, so i was checking out a video. and the frames have duration of 1024 and 512 alternatively. but this is constant frame rate how ? [13:32:44 CEST] <lain98> oh shit its an audio packet [13:41:56 CEST] <pomaranc> does anyone have an example HLS stream with webvtt subtitles? [13:42:07 CEST] <termos> hmm, I'm trying to init a bsf like so av_bitstream_filter_init("filter_units=remove_types=35") but it just returns nullptr, it's not null if I just try to specify the filter name "filter_units". Is there another way to specify the arguments? [13:42:24 CEST] <termos> I should probably switch to the non-legacy API, but just doing this as a quick test [16:30:04 CEST] <classsic> Hi somebody can explain what means the parameters "speed=1.01x" at the end of logs? [16:30:51 CEST] <FooNess> classsic, the speed of transcoding relative to the actual length of the media on the file. [16:31:18 CEST] <FooNess> classsic, so if you see, for example, "speed=1x" for a movie that lasts 90 minutes, the transcode took 90 minutes. [16:31:38 CEST] <FooNess> If you saw "speed=2.00x", then it took 45 minutes to transcode it. [16:31:44 CEST] <classsic> but, this appear when stream with vcodec copy to rtmp server, some cases under 1x [16:32:21 CEST] <FooNess> Right; it could be faster or slower than the original time. [16:32:26 CEST] <durandal_1707> yes, its normal [16:32:28 CEST] <FooNess> Depending on a lot of things. [16:32:38 CEST] <FooNess> Network latency/bandwidth, processing power, etc. [16:49:45 CEST] <classsic> but that not means something is wrong, right? [16:52:06 CEST] <kepstin> are you streaming from a file with -re, or restreaming another live source? [17:19:44 CEST] <classsic> kepstin restreaming frome another live source [17:34:51 CEST] <dastan> hello people [17:35:39 CEST] <dastan> i am redirecting the std out of a ffmpeg command to create a log [17:36:25 CEST] <dastan> and i want to read this log but i want to only show the speed, can someone help me with the scripting [17:37:12 CEST] <dastan> with ths next command i get speed=1.01 or speed=1.02 [17:37:44 CEST] <dastan> tail -f /home/build/MSS-ONE/temp/logs/TN-f9aa8baa/TN-f9aa8baa-cache.log | awk '/speed=/ { speed=$10 ; print speed ; }' [17:38:53 CEST] <dastan> how can i save the number 1.01 or 1.04 or 1 in the variable speed? [17:39:19 CEST] <pink_mist> since you're using awk, ask in an awk channel [17:39:21 CEST] <pink_mist> this is #ffmpeg [17:39:35 CEST] <dastan> there is a awk chnnel? [17:39:39 CEST] <pink_mist> no clue [17:40:20 CEST] <dastan> yep [17:40:21 CEST] <dastan> #awk [17:40:21 CEST] <pink_mist> #ffmpeg is not the awk channel however [17:40:36 CEST] <dastan> i am workiung with ffmpeg [17:40:39 CEST] <BtbN> You also asked the exact same question yesterday, and got a pretty good answer? [17:41:09 CEST] <pink_mist> you're working with text data. the fact that it's ffmpeg producing it is completely irrelevant [17:41:15 CEST] <dastan> we didnt get a solution with klaxa [17:41:55 CEST] <dastan> he was more friendly than you [17:42:20 CEST] <dastan> but dont worry, i will check in the awk channel [18:15:26 CEST] <durandal_1707> i want working solution now and for free [18:16:11 CEST] <durandal_1707> also ffmpeg developers do free consulting because it is free [18:46:34 CEST] <classsic> talking about logs output, ffmpeg don`t write logs line by line right? [18:47:12 CEST] <classsic> I get a looooooong line with speed, and other data. [19:00:46 CEST] <durandal_1707> you do something wrong [19:00:55 CEST] <durandal_1707> log output is fine [19:02:24 CEST] <classsic> ok, I execute ffmpeg inside docker, maybe that`s the problem [19:04:11 CEST] <kepstin> the stats line is terminated with \r instead of \n (that causes it to overwrite the same line on a terminal) [19:04:32 CEST] <kepstin> you need to account for that when splitting lines [19:06:24 CEST] <classsic> but I user tail .....ffmpeg.log, in bash env [19:07:04 CEST] <classsic> *i use [23:10:22 CEST] <TheDrode> Good afternoon, i am trying to re-stream an hls source to a Colable 5011 device using the command related in my pastebin (available in a second) I am getting broken video full of artifacts [23:10:26 CEST] <TheDrode> what am i doing wrong?
