Bug#946669: vlc: silently fails to play 32bit 48kHz Opus audio from mkv container
Package: vlc-plugin-base
Version: 3.0.8-0+deb10u1
Severity: serious
Justification: depend on libmatroska6v5 versioned too loosely
Playing an mkv video with 48kHz 32 bit Opus Audio results in total
silence. I tried alsa audio output, I tried pulseaudio output. Videos
with other codecs work correctly. I didn't try:
* other sampling frequency, or other bit depth, of Opus Audio
* Opus Audio in another container than mkv
I tried upgrading libopus0 to 1.3-1, same result.
vlc -vvv output:
This is caused by:
[0000556bdfd5bc60] main libvlc warning: cannot load module `/usr/lib/x86_64-linux-gnu/vlc/plugins/demux/libmkv_plugin.so' (/usr/lib/x86_64-linux-gnu/vlc/plugins/demux/libmkv_plugin.so: undefined symbol: _ZN11libmatroska27KaxVideoProjectionPosePitch10ClassInfosE)
which is solved by upgrading libmatroska6v5 from version 1.4.5-2 to
1.4.9-1. This suggests that the depends of vlc-plugin-base on
libmatroska6v5 (>= 1.4.5)
should be versioned more strictly, to require a higher version, making
this a Policy-serious bug.
Note that the "messages" window of vlc didn't show any error, nor did
stderr. They should have, which would have clued me in as to the
problem, before I ran with "-vvv" as instructed by reportug for this
bug report.
