NvMediaReferenceFrameH264 Struct Reference

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
• Be derived from the bitstream using a mechanism described in the specification.

Field Documentation

bottom_is_reference

uint32_t NvMediaReferenceFrameH264::bottom_is_reference

Is the bottom field used as a reference.

Set to false for unused entries.

Definition at line 256 of file nvmedia_common_decode.h.

field_order_cnt

int32_t NvMediaReferenceFrameH264::field_order_cnt[2]

[0]: top, [1]: bottom

Definition at line 258 of file nvmedia_common_decode.h.

FrameIdx

uint16_t NvMediaReferenceFrameH264::FrameIdx

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

Definition at line 264 of file nvmedia_common_decode.h.

is_long_term

uint32_t NvMediaReferenceFrameH264::is_long_term

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

Definition at line 246 of file nvmedia_common_decode.h.

not_existing

uint16_t NvMediaReferenceFrameH264::not_existing

Parser only: Non-existing reference frame flag (corresponding PicIdx should be set to -1)

Definition at line 269 of file nvmedia_common_decode.h.

surface

NvMediaRefSurface* NvMediaReferenceFrameH264::surface

The surface that contains the reference image.

Set to NULL for unused entries.

Definition at line 244 of file nvmedia_common_decode.h.

top_is_reference

uint32_t NvMediaReferenceFrameH264::top_is_reference

Is the top field used as a reference.

Set to false for unused entries.
