Vorbis dev - May 2004 - Multi-stream vorbis...

I've been testing my multi-stream mux directshow filter. And have created
some files with 2 tracks of vorbis... varying from 2 mp3s transcoding to
vorbis interleaved to one mp3 transcode to vorbis in one stream, and live
muxed spoken audio encoded to vorbis in the other. Simliarly some with
vorbis in one stram and speex encoded voice-overs in the other.

My directshow filters can play these files just fine, but that's no
assurance that they are correctly muxed. But my problem is i can't find any
other media player on windows that can handle these streams.

I've tried

VLC 0.72 - Only plays the first vorbis stream. Just ignores the second one.
MPlayer 6.4.8.2 - Rejects the file. Uses directshow (i think). I think this
is due to it enforcing the use of a source filter instead of letting
directshow choose, which would choose mine and hence be able to play.
BSPlayer 1.00 RC1 Build 808 - Only play first vorbis stream. Uses directshow
(i think) Same as MPlayer i think it is enforcing the use of a source filter
other than mine.

As an experiment, i tried uninstalling my directshow filters and tried
again.

VLC behaves the same.
MPlayer now rejects all ogg files, which indictes it was at least partly
using my filters, but not correctly.
BSPlayer now rejects all ogg files as above.

What i'm after is a player that is known to play multi-audio logical stream
files correctly. If there are none for windows, are there some for linux, if
so what are they ?

Thanks.

Zen.

Note that according to spec "Ogg Vorbis" files are not muxed.  One 
vorbis stream, possibly chained at the end to another vorbis stream, 
nothing muxed (concurrent).

So you're breaking new ground here, and as such, you won't find much 
support from current players.
