copying chapter markers doesn't work with ogg

Description

Summary of the bug:
When using libopus you can't add chapter markers.

How to reproduce:

% wget https://freakshow.fm/podlove/file/5513/s/webplayer/c/episode/fs225-frontend-von-judaea.opus
% ffmpeg -i fs225-frontend-von-judaea.opus -c:a copy output.opus
ffmpeg version n4.0.3 Copyright (c) 2000-2018 the FFmpeg developers
  built with gcc 8.2.1 (GCC) 20180831
  configuration: --prefix=/usr --disable-debug --disable-static --disable-stripping --enable-fontconfig --enable-gmp --enable-gnutls --enable-gpl --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libdrm --enable-libfreetype --enable-libfribidi --enable-libgsm --enable-libiec61883 --enable-libjack --enable-libmodplug --enable-libmp3lame --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libv4l2 --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxcb --enable-libxml2 --enable-libxvid --enable-nvdec --enable-nvenc --enable-omx --enable-shared --enable-version3
(it's the archlinux package ffmpeg 4.0.3-1)

This is the fastest way to reproduce the problem right now. I tried different map variations (map_metadata, map_chapters, ...) extracting the metadata with ffmpeg shows the chapters.
Using other codecs like AAC doesn't have this problem.

% wget https://freakshow.fm/podlove/file/5514/s/webplayer/c/episode/fs225-frontend-von-judaea.m4a
% ffmpeg -i fs225-frontend-von-judaea.m4a -c:a copy output.m4a

just works.

PS can't select the correct version.

Oh yeah tried using a different container as well to no affect.

comment:2 Changed 6 weeks ago by cehoyos

  • Component changed from ffmpeg to avformat
  • Keywords ogg added; libopus removed
  • Priority changed from normal to minor
  • Reproduced by developer set
  • Status changed from new to open
  • Summary changed from copying chapter markers doesn't work with libopus to copying chapter markers doesn't work with ogg
  • Version changed from unspecified to git-master

For future tickets: Please always test current FFmpeg git head (nothing else is supported here) and provide the command line you tested together with the complete, uncut console output.

The bug is that the console output claims chapters are copied when writing ogg files, the missing chapters are an enhancement request.
