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.

int32_t NvMediaReferenceFrameH264::field_order_cnt[2]

[0]: top, [1]: bottom

Definition at line 211 of file nvmedia_common.h.

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 217 of file nvmedia_common.h.
