NvMediaPictureInfoH264 Struct Reference

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 NvMediaVideoDecoderRenderEx 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.
