AVI format can handle VBR audio provided audio chunks are of fixed duration
(cfr fixed duration video frames). Apply this approach to (always) parsed
raw AAC and (if parsed) to MPEG-1/2 audio.
See #368681.

Add support for more than one audio stream; write better AVIX

Fail if caps negotiation fails. Should fix#162184, and should

Original commit message from CVS:
Riff, EBML, fourcc etc. work. Not fully finished, but better than
what we used to have and definately worth a first broad testing.
I've revived rifflib. Rifflib used to be a bytestream-for-riff, which
just dup'ed bytestream. I've rewritten rifflib to be a modern riff-
chunk parser that uses bytestream fully, plus adds some extra functions
so that riff file parsing becomes extremely easy. It also contains some
small usability functions for strh/strf and metadata parsing. Note that
it doesn't use the new tagging yet, that's a TODO.
Avidemux has been rewritten to use this. I think we all agreed that
avidemux was pretty much a big mess, which is because it used all
sort of bytestream magic all around the place. It was just ugly.
This is a lot nicer, very complete and safe. I think this is far more
robust than what the old avidemux could ever have been. Of course, it
might contain bugs, please let me know.
EBML writing has also been implemented. This is useful for matroska.
I'm intending to modify avidemux (with a riffwriter) similarly. Maybe
I'll change wavparse/-enc too to use rifflib.
Lastly, several plugins have been modified to use rifflib's fourcc
parsing instead of their own. this puts fourcc parsing in one central
place, which should make it a lot simpler to add new fourccs. We might
want to move this to its own lib instead of rifflib.
Enjoy!
Original commit message from CVS:
Fix avimux (somewhat). Note: the EOS event still doesn't get through. This is completely braindead, I have no clue why, but setting this thing to PAUSE should do the trick too. EOS fix will come later on...
Original commit message from CVS:
Make it loopbased and use only one video and one audio pad. framerate is also no longer a property but is requested from the source pad
Original commit message from CVS:
WARNING: avimux is still broken, but less broken than it used to be... Code is under heavy development and will work sooner or later... Uploaded for generic development and testing purposes, not intended for generic use whatsoever
Original commit message from CVS:
made changes everywhere to accomodate for the headers being in
<gst/(lib)/...>
we'll need to conclude this fast because we will also need to change stuff in core real soon for the libs in order to fix everything
and I can't do it right now because I disabled all of the plugins here ;)
