 In the long term it would be nice to reduce dependencies and increase the
 number of supported audio codecs in mythmusic, to this end I'm creating
 this task ticket.

 Attached is a patch which switches OGG Vorbis decoding from libvorbis to
 ffmpeg's native decoder. It also fixes a long standing, but unreported bug
 in mythmusic's avfdecoder. Could anyone with lots of oggs in their audio
 collection please test this, since I only have a few short samples?

 If anyone knows of a list of native decoders in ffmpeg, or could list a
 few known audio codecs it can handle I can add them as supported formats
 to the AVF decoder. I know AAC decoding is currently being tested. Since
 mythmusic currently relies on the file extension to chose decoders, having
 the extensions would help a lot too.

 Related to this task is the ongoing conversion of replacing existing
 tagging libraries with taglib (supports Vorbis/Ogg Vorbis comments in a
 wide variety of containers and file formats in addition to mp3).
