The main problem with AVC levels is that J. Random Author has no idea  
what AVC level his/her tool emitted.

HTML5 needs to delegate it to something that is implementable given  
the APIs QuickTime, GStreamer, DirectShow and Phonon provide. A  
standard doesn't help if it doesn't match the APIs.

Does what HTML5 says now match the framework APIs?

The MIME codecs parameter seems to confuse both WebKit and Minefield,  
for instance:

vs.
