struct _VASliceParameterBufferHEVCExtension

HEVC Decoding Slice Parameter Buffer Structure For Long Format including Extensions

This data structure contains both baseline HEVC profiles (main, main10)

and extension profiles (range extension and screen content).

VASliceParameterBufferHEVCExtension structure should be accompanied by a

slice data buffer, which holds the whole raw slice NAL unit bit streams

including start code prefix and emulation prevention bytes not removed.

This structure conveys parameters related to slice segment header and should

be sent once per slice. For HEVC range extension and HEVC Scc decoding,

application should parse both basic slice parameters and extented slice

parameters into this buffer structure and sent it.

For short format, this data structure is not sent by application.
