Detailed Description

Picture parameter information for an H.264 picture.

Note: The referenceFrames array must contain the "DPB" as defined by the H.264 specification. In particular, once a reference frame has been decoded to a surface, that surface must continue to appear in the DPB until no longer required to predict any future frame. Once a surface is removed from the DPB, it can no longer be used as a reference, unless decoded again.

Also note that only surfaces previously generated using NvMediaIDERender may be used as reference frames.

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.
