#include <vdpau.h>
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 VdpDecoderRender may be used as reference frames. In particular, surfaces filled using any "put bits" API will not work.
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.
