Yes, as of right now, all the streams are uncompressed.  The 
MF_PD_MIME_TYPE attribute on the other hand doesn't specify the type of 
the streams (after all, it's only set on a per presentation descriptor 
basis).  I think it's safe to assume it represents the mime type of the 
input data, which all streams share.  The documentation on this is again 
lacking.

Yes, this should be possible, I would assume it's sent through a tag event.
