xmms-oggre | ogg disk output plugin for XMMS | Mehr ...
Oggre allows you to directly output Ogg Vorbis files from XMMS, in the same style as the standard Disk Writer plugin. You can also specify output quality. Oggre is a fast way to transcode all of the items in a playlist to Vorbis, or to convert a file type that XMMS can play into a Vorbis file for other media players.
