Detailed Description

Information about an H.264 reference frame.

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.

Data Fields
VdpVideoSurface	surface
VdpBool	is_long_term
VdpBool	top_is_reference
VdpBool	bottom_is_reference
int32_t	field_order_cnt [2]
uint16_t	frame_idx

Field Documentation

VdpVideoSurface VdpReferenceFrameH264::surface

The surface that contains the reference image. Set to VDP_INVALID_HANDLE for unused entries.

VdpBool VdpReferenceFrameH264::is_long_term

Is this a long term reference (else short term).

VdpBool VdpReferenceFrameH264::top_is_reference

Is the top field used as a reference. Set to VDP_FALSE for unused entries.

VdpBool VdpReferenceFrameH264::bottom_is_reference

Is the bottom field used as a reference. Set to VDP_FALSE for unused entries.

int32_t VdpReferenceFrameH264::field_order_cnt[2]

[0]: top, [1]: bottom

uint16_t VdpReferenceFrameH264::frame_idx

Copy of the H.264 bitstream field: frame_num from slice_header for short-term references, LongTermPicNum from decoding algorithm for long-term references.
