Detailed Description

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

Note: References to "copy of bitstream field" in the field descriptions may refer to data literally parsed from the bitstream, or derived from the bitstream using a mechanism described in the specification.

Field Documentation

uint8_t VdpPictureInfoMPEG1Or2::alternate_scan

Copy of the MPEG bitstream field.

VdpVideoSurface VdpPictureInfoMPEG1Or2::backward_reference

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

uint8_t VdpPictureInfoMPEG1Or2::concealment_motion_vectors

Copy of the MPEG bitstream field.

uint8_t VdpPictureInfoMPEG1Or2::f_code[2][2]

Copy of the MPEG bitstream field. 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

Copy of the MPEG bitstream field.

uint8_t VdpPictureInfoMPEG1Or2::full_pel_backward_vector

Copy of the MPEG-1 bitstream field. For MPEG-2, set to 0.

uint8_t VdpPictureInfoMPEG1Or2::full_pel_forward_vector

Copy of the MPEG-1 bitstream field. For MPEG-2, set to 0.

Copy of the MPEG bitstream field, converted to raster order.

uint8_t VdpPictureInfoMPEG1Or2::picture_coding_type

Copy of the MPEG bitstream field.

uint8_t VdpPictureInfoMPEG1Or2::picture_structure

Copy of the MPEG bitstream field.

uint8_t VdpPictureInfoMPEG1Or2::q_scale_type

Copy of the MPEG bitstream field.

uint32_t VdpPictureInfoMPEG1Or2::slice_count

Number of slices in the bitstream provided.

uint8_t VdpPictureInfoMPEG1Or2::top_field_first

Copy of the MPEG bitstream field.
