\brief Picture parameter for MPEG-2 encoding

This structure holds information for picture_header() and picture_coding_extension()

If packed picture headers mode is used, i.e. if the encoding pipeline was configured with the #VA_ENC_PACKED_HEADER_PICTURE flag, then the driver expects two more buffers to be provided to the same \c vaRenderPicture() as this buffer:

• a #VAEncPackedHeaderParameterBuffer with type set to VAEncPackedHeaderType::VAEncPackedHeaderPicture ;
• a #VAEncPackedHeaderDataBuffer which holds the actual packed header data.

Fields

forward_reference_picture: VASurfaceID

\brief Forward reference picture

backward_reference_picture: VASurfaceID

\brief Backward reference picture

reconstructed_picture: VASurfaceID

\brief Reconstructed(decoded) picture

coded_buf: VABufferID

\brief Output encoded bitstream.

\ref coded_buf has type #VAEncCodedBufferType. It should be large enough to hold the compressed NAL slice and possibly SPS and PPS NAL units.

last_picture: u8

\brief Flag to indicate the picture is the last one or not.

This fields holds 0 if the picture to be encoded is not the last one in the stream. Otherwise, it is \ref MPEG2_LAST_PICTURE_EOSTREAM.

picture_type: Type

\brief Picture type

temporal_reference: u32

\brief Same as the element in picture_header()

vbv_delay: u32

\brief Same as the element in picture_header()

f_code: [[u8; 2]; 2]

\brief Same as the element in Picture coding extension

picture_coding_extension: _VAEncPictureParameterBufferMPEG2__bindgen_ty_1

composite_display: _VAEncPictureParameterBufferMPEG2__bindgen_ty_2

va_reserved: [u32; 4]

\brief Reserved bytes for future use, must be zero
