Hi all, i would like to know if you have found the solution for your problem. I
have to extract motion vectors from mpeg stream. I just started doing that, and
at the moment, i need to know if it is possible to do it. Any help will be
highly apreciated.
Thanks

Hi all,
I've been looking for a quick way to extract the motion vectors from a
MPGE2 file.After being throughly frustrated with ffmpeg, I stumbled
across libmpeg2 yesterday and was elated to find mpeg2dec. However, I
was wondering if someone could explain the motion vector structure:
typedef struct {
uint8_t * ref[2][3];
uint8_t ** ref2[2];
int pmv[2][2];
int f_code[2];
} motion_t;
and how slice determines the next p frame from it.
Thanks,
Sean McVeigh
