I can build vlc 2.0.8-1 fine (after adding --disable-live555
to the configure), but when I try to play a video I get
something like this (using the -v flag on the command
line):
[0x...] main decoder warning: cannot load module `/usr/lib/vlc/plugins/codec/libavcodec_plugin.so' (/usr/lib/vlc/plugins/codec/libavcodec_plugin.so: undefined symbol: avcodec_open) [0x...] main decoder error: corrupt module: /usr/lib/vlc/plugins/codec/libavcodec_plugin.so [0x...] main decoder error: no suitable decoder module for fourcc `h264'. VLC probably does not support this sound or video format. I've already fixed It should be using libavcodec 53 from ffmpeg-compat, and it does seem at least think it is, because it appears to be using avcodec_open instead of avcodec_open2 (which it uses for libavcodec >= 54), and also because it actually builds (removing the ffmpeg-compat pkgconfig from the configure makes the build fail claiming not to support avcodec 55+). However, running ldd on /usr/lib/vlc/plugins/codec/libavcodec_plugin.so shows it linked against libavcodec.so.55, so something seems to be using the wrong version. Forcing the old version in with LD_PRELOAD makes the module load but it (predictably) fails to actually open the codec ("codec type or id mismatches"). Basically, at some point in the build process it's using the non-compat version of the ffmpeg libs, but I have no idea why. I suppose it could be something weird about my system, but I'm not doing anything fancy with the build right now so I'm not sure what it would be. |
This task depends upon

Additional comments about closing: VLC in repositories is correctly build against ffmpeg-compat. There is nothing to fix from our side.
