 I already figured that the decoders do not all support float output, so I have 
added code
to do so myself.

The big problem I have now is that I want to save the buffers in memory 
(floats, mono or stereo)
to a file with a format selected from a popup menu and a chosen codec to use.

Creating the BMediaFile works ok, CheckInit() too, but then trying to create 
the BMediaTrack
always failes, no matter what I try.

Does anyone of you have a codesnippet that shows me how to do so ????

I need to be able to save off mono/stereo in 8, 16 or 32 bit with a selected 
codec and check
whether the codec does support it.

Frans van Nispen.
