VLC can't play videos with Opus audio
Only tested 3 configurations of files:
- Ogv (Ogg) containing VP8/Opus (won't play at all in VLC)
- WebM containing VP8/Opus (won't play audio in VLC)
- WebM containing VP9/Opus (won't play audio in VLC)
- Oga (Ogg) containing Opus audio only (plays fine in VLC)
All files play perfectly fine in ffplay, totem (gstreamer), mplayer, firefox (on gnu, so this is also gstreamer AIUI), and Chrome, with the exception of the Ogv file not showing the video in Firefox.
In the ones that play video, but not audio, this is the error given: "No suitable decoder module: VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this."
