Field Documentation

uint8_t VdpPictureInfoMPEG1Or2::alternate_scan

VdpVideoSurface VdpPictureInfoMPEG1Or2::backward_reference

Reference used by B frames. Set to VDP_INVALID_HANDLE when not used.

uint8_t VdpPictureInfoMPEG1Or2::concealment_motion_vectors

uint8_t VdpPictureInfoMPEG1Or2::f_code[2][2]

For MPEG-1, fill both horizontal and vertical entries.

VdpVideoSurface VdpPictureInfoMPEG1Or2::forward_reference

Reference used by B and P frames. Set to VDP_INVALID_HANDLE when not used.

uint8_t VdpPictureInfoMPEG1Or2::frame_pred_frame_dct
