Detailed Description

Picture parameter information for an MPEG 1 or MPEG 2 picture.

Note: References to bitstream fields below may refer to data literally parsed from the bitstream, or derived from the bitstream using a mechanism described in the specification.

Field Documentation

◆ alternate_scan

uint8_t VdpPictureInfoMPEG1Or2::alternate_scan

◆ backward_reference

VdpVideoSurface VdpPictureInfoMPEG1Or2::backward_reference

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

◆ concealment_motion_vectors

uint8_t VdpPictureInfoMPEG1Or2::concealment_motion_vectors

◆ f_code

uint8_t VdpPictureInfoMPEG1Or2::f_code[2][2]

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

◆ forward_reference

VdpVideoSurface VdpPictureInfoMPEG1Or2::forward_reference

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

◆ frame_pred_frame_dct

uint8_t VdpPictureInfoMPEG1Or2::frame_pred_frame_dct

◆ full_pel_backward_vector

uint8_t VdpPictureInfoMPEG1Or2::full_pel_backward_vector
