Expand description

What the session negotiated at open, which the codec arms read.

Fields§

§profile: VAProfile§entrypoint: VAEntrypoint§packed: u32

The packed headers the driver takes, VA_ENC_PACKED_HEADER_* bits.

§rc_mode: u32

The rate-control mode, VA_RC_CQP or VA_RC_CBR.

§width: u32§height: u32§fps: FrameRate§bits_per_second: u32§dpb: u32

The reference frames the decoded picture buffer holds.

§dpb_level: u32

The level the decoded picture buffer was sized for, the lowest an H.264 or HEVC sequence declares.

§fullcolor: bool§bit_depth: u32§min_qp: u32

The quantizer bounds of a constant-rate session in the codec’s own domain, 0 for none.

§max_qp: u32§qp_floor: u32

The finest quantizer the entry point codes a constant-quantizer picture at (h265::INTEL_LOW_POWER_MIN_QP on Intel’s low-power HEVC encoder, 1 elsewhere).

§unit_qp_deltas: bool

Whether the driver’s rate control codes its quantizer in every coding unit as a delta from the slice’s (Intel’s full HEVC encoder), which the slice’s quantizer then has to keep within the syntax’s range (h265::Arm::configure).

§h264_driver_level: u32

The highest H.264 level the driver is told (Device::h264_driver_level); the packed SPS still declares the level the stream needs.

§roi_regions: u32

The regions of interest a frame may name with a quantizer delta (VAConfigAttribEncROI), 0 where the driver takes none, or none under its rate control at a constant rate.
