Note for H264 header parsing performance, h264parse does not keep it's parsing
context, hence re-parse the same buffer over and over. I think there is a bug
for that, which I can't find now, but I'm sure I've created it. As the h264
header parsing is pretty performant already (with the byte skipping algorithm),
I'd focus on fixing this first, before going into having to maintain assembly
code.
