i am currently trying to extract all frames from a given *.mp4 file using
the c++ headers. However i am getting several error messages trying to
extract (using avcodec_decode_video2), namely:

Marker bit missing before time_increment_resolution
Marker bit missing before fixed_vop_rate
Marker bit missing before width
Marker bit missing before height
Marker bit missing after height
Marker bit missing in complexity estimation part 1
[mpeg4 @ 0176a220] hmm, seems the headers are not complete, trying to guess
[mpeg4 @ 0176a220] my guess is 16 bits ;)
Marker bit missing before vop_coded

Here's the relevant code: http://pastebin.com/gsbTFqxF

I would much appreciate any help!

Thanks in advance
