Read h264.c, read the h.264 spec, learn C, find out where the problem is
fix it and send a patch here (and skip what you already did like learning C

You misunderstand things a little
you want it fixed -> you fix it
you dont want it fixed -> you dont fix it
you want someone else to fix it -> you pay someone else to fix it
If you expect us to work for you for free then you have a serious problem
with reality, we are volunteers and we work on what we consider fun. H.264
especially PAFF work is not fun.
Our H264 decoder does not support everything, no h264 decoder does, not
even the reference decoder. If you want some specific feature supported
its up to you to do the work. We will certainly help, awnser questions and
