#include <vdpau.h>
Picture parameter information for an H.265/HEVC picture.
References to bitsream fields below may refer to data literally parsed from the bitstream, or derived from the bitstream using a mechanism described in Rec. ITU-T H.265 (04/2013), hereafter referred to as "the H.265/HEVC Specification".
VDPAU H.265/HEVC implementations implement the portion of the decoding process described by clauses 8.4, 8.5, 8.6 and 8.7 of the the H.265/HEVC Specification. VdpPictureInfoHEVC provides enough data to complete this portion of the decoding process, plus additional information not defined in the H.265/HEVC Specification that may be useful to particular implementations.
Client applications must supply every field in this struct.

Section 7.6.3.1 of the H.265/HEVC Specification defines the syntax of the slice_segment_header. This header contains information that some VDPAU implementations may choose to skip. The VDPAU API requires client applications to track the number of bits used in the slice header for structures associated with short term and long term reference pictures. First, VDPAU requires the number of bits used by the short_term_ref_pic_set array in the slice_segment_header.
