Comment (by markfilipak):
Balling, my friend, if you're hoping I can help you, I'll tell this:
H.264 architecture does not have I- P- or B-frames. If x264 does, then
x264 is in error.
H.264 architecture does have I- SI- P- SP- and B-slices.
I think that access units are virtual: network abstraction units (NAL
units) that are collections of I- SI- P- SP- and B-slices that are
delivered in packets that used to be called "PES".
I think that elemental streams (ES) have been demoted to simply be access
unit delivery vehicles.
I think that NAL unit 5 is the physical tag for IDR.
