Parameters:
- Mpeg2PicHdr *fh
- Previously allocated and initialized Mpeg2PicHdr structure.
- intvec_select
- 0 or 1, used to select either the first or second vector.
- intvec_dir
- 0 or 1, used to select either forward or backward (respectively).
- intcomp_value
- Vector component value.
Return value:
None.
Description:
Set the horizontal vector component of the motion vector predictor selected by the parameters vec_select and vec_dir. There are four predictors (first forward, second forward, first backward, second backward). The parameter vec_select indicates first or second, the parameter vec_dir indicates forward or backward.
