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.
