struct _VAEncSequenceParameterBufferH264

Defined at line 148 of file ../../third_party/intel/libva/va/va_enc_h264.h

Sequence parameter for H.264 encoding in baseline, main

&

high

profiles.

This structure holds information for

as

defined by the H.264 specification.

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

pipeline was configured with the #VA_ENC_PACKED_HEADER_SEQUENCE

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

the same

as this buffer:

- a #VAEncPackedHeaderParameterBuffer with type set to

VAEncPackedHeaderType::VAEncPackedHeaderSequence ;

- a #VAEncPackedHeaderDataBuffer which holds the actual packed

header data.

If

is set to

then a

#VAIQMatrixBufferH264 buffer shall also be provided within the same

call as this sequence parameter buffer.
