I guess we still have no decision on this.

Guess everyone agrees on 'avc' for avc sample/format.

The remaining problem is with byte-stream, that might be parsed in AU or NALU

I'll try to summarize here what I understood from the discussion:

* Option 1:
Use byte-stream-nalu and byte-stream-au, the problem here is what would mean
having those formats with parsed=false.

This solution seems to be having the following combinations as 'valid':
byte-stream, parsed=false
byte-stream-nalu/au, parsed=true.

* Option 2:
Use format=byte-stream and allow parsed to be 'none', 'au', 'nalu'. This works
as well, but it breaks our usual parsed=false/true logic.

* Option 3 (hybrid):
Use format=byte-stream, keep parsed=true/false but add a new alignment=au/nalu

I particularly don't like option 2 because parsed=true/false is already used
for other formats and is kind of convention. But I have no strong opinion about
1 or 3, though I prefer 3.
