There's a problem with this, too. You need a way to identify an extradata 
buffer as an extradata buffer.
You must make sure that the extradata is sent when expected, you must define a 
format for it and you must make sure every demuxer sends the extradata in the 
right format.
You also need to define how extradata buffers are related to events and so on.

All of this was implicitly done by using caps.
