ampache default config has oggsplit as ogg transcoder http://xpisar.wz.cz/ebuilds/portage/media-sound/oggsplit/oggsplit-9999.ebuild http://svn.xiph.org/trunk/ogg-tools/oggsplit/ oggsplit - splits multiplexed Ogg files oggsplit is a simple tool for splitting multiplexed (grouped or chained) Ogg files into separate streams. It can thus be used to take apart two concatenated streams (i.e. it undoes the process of cat file1.ogg file2.ogg > file3.ogg) or to split two streams which are grouped, for example the video and audio streams in a theora+vorbis file.
Is there a link to a released version? Otherwise we'd have to make a snapshot.
I've committed the live ebuild to the Gentoo Multimedia overlay.
