+1 on something like this. There has to be some sort of official spec for 
it, with at least a handwavy acknowledgement from Adobe.

And some more extensible way of signaling codecs might be good like JB 
suggests (although it makes the FLV stream much more cumbersome compared 
to other codecs), because the field only allows IDs 0-15, out of which 
already over half of them are defined, and if defining more of them, we're 
very soon out of numbers.
