struct _VAEncSliceParameterBufferH264

Defined at line 420 of file ../../third_party/intel/libva/va/va_enc_h264.h

Slice parameter for H.264 encoding in baseline, main

&

high profiles.

This structure holds information for

as defined by the H.264

specification.

If packed slice headers mode is used, i.e. if the encoding

pipeline was configured with the #VA_ENC_PACKED_HEADER_SLICE

flag, then the driver expects two more buffers to be provided to

the same

as this buffer:

- a #VAEncPackedHeaderParameterBuffer with type set to

VAEncPackedHeaderType::VAEncPackedHeaderSlice ;

- a #VAEncPackedHeaderDataBuffer which holds the actual packed

header data.

If per-macroblock encoder configuration is needed,

references a buffer of type #VAEncMacroblockParameterBufferH264. This

buffer is not passed to vaRenderPicture() and it can be re-used

without re-allocating the whole buffer.
