Um... How factorize? I can imagine adding another out parameter for 
ff_h264_decode_nal() for bit length which would be filled with NAL bit 
size. I'm afraid, it won't save more than 1-2 LOC, though.

I've attached the two patches as it is right now for your reference.

BTW, I've posted the whole load of trivial patches and ~4 parser patches 
including proper timestamping of H.264 together in one post to the ML a 
few minutes ago to have a consolidated view of the things. I'd be happy 
if at least trivial prereqs got committed, since it's pretty hard to get 
the hunks separated when updating a patch (and thus, I have to spend 80% 
of the time just managing hunks instead of doing some productive work).

Regards,

Ivan
