Ronald 'BBB' Bultje, one of the core devs of the Gstreamer team is
reading here AFAIK, so he could make contact i guess.
The Gstreamer people do have a nice API with their 'gst plugin API'
AFAIK, but it doesnt help them a lot as its tied to Gstreamer as a
framework and so no codec developers will support it natively. So, in
the end, they have to make all the plugins themselves now ( i guess BBB
is doing that ) and also maintain them.
If there was a common opensource codec API, a standard wrapper plugin
could be enought for them maybe to cover most formats ?
I was talking with Erik 'omega' Waltinsen a couple of times on IRC, he's
the founder of Gstreamer and does certainly know a lot about this kind
of stuff, and he told me he had a neat concept in the very back of his
brains already, but just no time to bring it onto paper. Maybe if you
guys showed some real interest in cooperating with them here, you could
start an avalanche ....

Exactly my thoughts also. Must be because we're both Germans Guenter :-D !!
