GStreamer needs a way to send different buffer types with the same caps.
David suggested adding an int to the GstBuffer struct but I'm not sure if
we should add even more stuff to GstBuffer. It sounds like the best
solution though atm.

Where's this needed / could this be used:
- here in your colour lookup tables
- interleaved video
- float audio for the different channels
- setup data in some streams (svq3, wma)

I'm however not sure this is a good way to do this and if it can't be
solved better somehow. Especially since none of those formats are really
though through...
