h264: check the pixel format directly and force a reinit on mismatches.
The existing checks are insufficient to detect a pixel format changes in case of some damaged streams. Fixes inconsistency and later out of array accesses Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at> (cherry picked from commit 11c99c78bafa77f679a1a3ba06ad00984b9a4cae) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
