New description:

 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?

 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).
