#8085: ffprobe - report if audio is vbr -------------------------------------+------------------------------------- Reporter: | Type: cobaltjacket | enhancement Status: new | Priority: wish Component: ffprobe | Version: 4.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Currently, ffprobe reports an average bitrate for audio streams. It would be useful to not only report this, but also to report if a given stream is variable bitrate (VBR). As a human, I can guess this, but I am utilizing the JSON output from ffprobe programmatically. -- Ticket URL: <https://trac.ffmpeg.org/ticket/8085> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#5750(ffmpeg:new): ffmpeg generates rarerly PCR for mpegts with multiple video streams copy and muxrate specified.

#5750: ffmpeg generates rarerly PCR for mpegts with multiple video streams copy and muxrate specified. --------------------------------+--------------------------------------- Reporter: xzerth | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------+--------------------------------------- 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 ffmpeg version 3.1.1 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 4.9.2 (Ubuntu 4.9.2-0ubuntu1~12.04) configuration: --prefix=/usr/local --pkg-config-flags=--static --enable- static --disable-shared --disable-avdevice --enable-runtime-cpudetect --disable-postproc --enable-libfdk-aac --enable-libmp3lame libavutil 55. 28.100 / 55. 28.100 libavcodec 57. 48.101 / 57. 48.101 libavformat 57. 41.100 / 57. 41.100 libavfilter 6. 47.100 / 6. 47.100 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

#8039: mpegtsenc: incorrect PCR with multiple programs -----------------------------------+-------------------------------------- Reporter: ahakon | Type: defect Status: new | Priority: important Component: avformat | Version: git-master Keywords: mpegtsenc | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- Summary of the bug: The MPEG-TS muxer has a '''serious''' bug related to the PCR pid selection. This bug appears when more than one program is used. The root cause is because the current code targets only one program when selecting the stream for the PCR. How to reproduce: [ test file "Day_Flight.mpg" from https://samples.ffmpeg.org/MPEG2/mpegts-klv/Day%20Flight.mpg ] {{{ % ffmpeg -loglevel verbose -y -f mpegts -i Day_Flight.mpg \ -map i:0x1e1 -c:v:0 copy -map i:0x1e1 -c:v:1 copy \ -program st=0 -program st=1 -f mpegts out-error.ts }}} If you analyze the output, you can see that the file "out-error.ts" has PCR marks in every packet of the pid 256 (a total of 561862 packets with PCR marks). However, the pid 257 has 783 packets only with PCR marks. Current source code of the mpegts muxer only initializes the PCR of one program. Other programs are unintialized. And this is a bug. Regards.
