[FFmpeg-devel] [PATCH] Fix empty G-VOP header decoding in MPEG-4

[Anatoly Nenashev]

Hi all!
There are some cameras which send mpeg-4 streams with empty G-VOP header.
This part of stream looks like this:
... 00 00 01 B3 00 00 00 01 B6 ...
Sample file uploaded in issue 2592.
FFmpeg reports "header damaged" and ignores first I-frame in G-VOP.
Attached patch fix this problem.

Anatoly.
