[MEncoder-users] ogm2avi script

[David Ward]

Didn't read it in full, but the idea of an OGM container to to contain 
files that an AVI container cannot.  Namely Ogg Vorbis audio.  It does 
appear though that the scripts changes the audio to mp3.

Personally, i would use ogmdemux.  As stated in its man:

        This  program  extracts all or only some streams from an OGM and writes

       them to separate files.



Hope that helps.
