Description

Summary of the bug:
I'm trying to copy multiple video streams from one mpegts file to another. The problem is that PCR generated by ffmpeg from this procedure repeates very rarerly and looks very "bad". For example:

*pcr, BASE, EXT, dSTC(ms), dPCR(ms), PCR-STC(ns), 
*pcr,      97790029,     325966, 229, +19.899, +19.899,   +0, 
*pcr,      98327304,     327757, 204, +19.899, +19.899,   +0, 
*pcr,     101919550,     339731, 250, +133.046, +133.046,  +37, 
*pcr,     102463073,     341543, 173, +20.130, +20.130,   +0, 
*pcr,     124316424,     414388,  24, +809.384, +809.383, -815, 
*pcr,     154266386,     514221,  86, +1109.258, +1109.258,   +0, 
*pcr,     168875895,     562919, 195, +541.093, +541.093,  +37, 
*pcr,     174392335,     581307, 235, +204.313, +204.313,   +0, 
*pcr,     180349217,     601164,  17, +220.625, +220.625,  +74, 
*pcr,     194649480,     648831, 180, +529.639, +529.639,   +0, 
*pcr,     195186755,     650622, 155, +19.899, +19.899,   +0, 
*pcr,     196504953,     655016, 153, +48.822, +48.822,  +37, 
*pcr,     197257763,     657525, 263, +27.882, +27.882,  +37, 

as you can see sometimes dPCR reaches up to +1038.984 ms in this log (next to the last column) and with my stream I've seen about 2k or 3k ms! Muxrate option specified but it seems it is ignored. Also if I transcode video streams there is no problem. Problem only with -copy option. Also if I specify less number of video streams it seems that problem affects less - PCR generates smoother: if I specify 1 track (also reduce muxrate) the problem not produces.

How to reproduce:

% ffmpeg -i pipe:0 -codec:0 copy -map 0:0 -codec:1 copy -map 0:1 -codec:2 copy -map 0:2 -codec:3 copy -map 0:3 -codec:4 copy -map 0:4 -codec:5 copy -map 0:5 -max_delay 3000000 -muxrate 13000k -f mpegts pipe:1 < input.ts > out_bad_pcr.ts

The upload file size is very small and the problem reproduces with multiple streams so if it's not representative, I upload bigger file to google drive:

  • Keywords mpegts added

How can I reproduce the PCR frequency?
(And why are you using pipe input and output?)

Unrelated:
--enable-static --disable-shared --enable-runtime-cpudetect have no effect.
--disable-postproc has no effect in your configure line (only if --enable-gpl is specified)
--prefix=/usr/local should be the default

comment:6 Changed 2 years ago by xzerth

You can reproduce the problem with my command. Or what are you asking about? For analyzing PCR I'm using tstools.
Also if you want to see better PCR which corresponds muxrate, you can just decrease number of copy streams:

~# bin/ffmpeg -i pipe:0 -codec:0 copy -map 0:0 -codec:1 copy -map 0:1 -max_delay 3000000 -muxrate 1000k -f mpegts pipe:1 < input.ts > out.ts

So what I get the problem exists but signified less:

*pcr,      98689680,     328965, 180, +18.382, +18.382,   +0,

*pcr,     113985360,     379951,  60, +18.382, +18.382,   +0, 

And for single stream copy:

~# bin/ffmpeg -i pipe:0 -codec:0 copy -map 0:0 -max_delay 3000000 -muxrate 500k -f mpegts pipe:1 < input.ts > out.ts

the generated PCR looks as it should be, the "good" PCR:

*pcr,      84821904,     282739, 204, +18.048, +18.048,   +0,

I'm using pipe because it's convenient with my encoding environment.
Thanks for notice about build flags - it's remain from another build

What do I have to do with tstools to get the output you provided?

Changed 2 years ago by xzerth

pcr_diff.py

comment:8 Changed 2 years ago by xzerth

Ok, now I understand :) To see the problem I'm using also my scripts. This output from my analyzing system (which uses tstools sometimes).
I wrote simple script for you to detect the problem and attached it. You can run it with python2 pcr_diff.py out.ts -- It's extract PCRs and calculates those diffs.
Also you may check the output from tstools with tsreport -v out.ts | grep ".. PCR " -- it's just extracting PCRs so you need to calculate it by hand but my script already do this.

Is the issue also reproducible if you reencode (to x264 or mpeg2video)?
Is it also reproducible when remuxing mpeg2video?

Replying to cehoyos:

Is the issue also reproducible if you reencode (to x264 or mpeg2video)?
Is it also reproducible when remuxing mpeg2video?

No, as I already wrote the problem is not reproduces if I transcode it.
Yes, it is also reproducible when remuxing mpeg2video

Transcode with libx264:

I've tried both 3.1.1 and git master head.
Are you still can't reproduce the problem? I have 100% reproducibility.

Replying to xzerth:

I was just wondering if the issue is related to h264 timestamps (that are known to cause issues in FFmpeg).

Understand. Well, I have no problem with transcoding streams. Only with copying. Maybe the problem here because of vbv buffer which requirments ffmpeg do not take into account while copying streams?

comment:13 Changed 2 years ago by xzerth

Hi, is there any news? Can you reproduce behavior? Can I help you and provide more info?
There is 3.1.2 release soon - is this bug serious or we can catch the bus? )

comment:14 Changed 2 years ago by cehoyos

If this is not a regression, I would strongly suggest not to backport a fix, this nearly always leads to trouble.

I hit a very similar issue by demuxing a TS file which has multiple video and audio streams. (Different resolutions and different compressions)
My command line was:
ffmpeg -i big.ts -map 0:0 -vcodec copy video01.ts

The output file had PCR entries sporadically, ~23ms - ~8s intervals random.
I executed ffmpeg on Windows and tried 2 versions:
ffmpeg-20180319-e4eaaf7-win64-static --> issue can be reproduced
ffmpeg-20140525-git-f276bf3-win64-static --> output has PCR every 67ms

I checked out the 2014 version from GIT (f276bf303cbb7a8fed3c388135007bc29f45f8d5) and run it on Linux. It worked fine.
Something had to happen between 2014 and 2016 which broke the functionality.
As soon as I will have some time I will try to find out which commit broke the code.

Output PCR differences using the 20180319 version: (seconds)
1.735, 1.969, 3.303, 2.035, 4.771, 1.201, 1.134, 0.968, 1.001, 1.001, 1.502, 1.502, 1.201, 8.308, 1.168, 2.069
and using the 20140525 version: (seconds)
0.067, 0.067, 0.067, 0.067, 0.067, 0.067, 0.067

Original file has PCR values in every 0.067 seconds (sometimes 0.033 seconds)

Output of the 2014 version:
