 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

 }}}
 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.
