Struct QsvAv1Params 

pub struct QsvAv1Params {
    pub rc_mode: QsvRateControl,
    pub icq_quality: u16,
    pub qp_i: u16,
    pub qp_p: u16,
    pub target_usage: u16,
    pub gop_pic_size: u16,
    pub num_tile_columns: u8,
    pub num_tile_rows: u8,
    pub low_power: u16,
}

Concrete parameters for Intel QSV AV1 (oneVPL on Arc / Meteor Lake+).

oneVPL is struct-driven: mfxVideoParam carries every knob in fixed fields (no property bag). The adapter produces the exact values we splat into the struct in crates/codec/src/encode/qsv.rs.

Fields

rc_mode: QsvRateControl

mfxVideoParam.mfx.RateControlMethod. ICQ for the common quality targets; CQP for archive.

icq_quality: u16

mfxVideoParam.mfx.ICQQuality (ICQ mode) — 1..51 for AV1 per oneVPL 2.8+ dispatcher. 1=best, 51=worst. Mapped from libaom CQ.

qp_i: u16

mfxVideoParam.mfx.QPI (CQP mode) — AV1 q-index 0..255.

qp_p: u16

mfxVideoParam.mfx.QPP (CQP mode) — inter-frame QP.

target_usage: u16

mfxVideoParam.mfx.TargetUsage. 1=best quality, 7=best speed.

gop_pic_size: u16

mfxVideoParam.mfx.GopPicSize. Frames between keyframes.

num_tile_columns: u8

Tile grid — mfxExtAV1TileParam.NumTileColumns / NumTileRows.

num_tile_rows: u8

low_power: u16

mfxVideoParam.mfx.LowPower. Always MFX_CODINGOPTION_OFF = 32 for this service — the low-power path on older Arc silicon has documented quality regressions; leaving it explicitly OFF sidesteps that.

Trait Implementations

impl Clone for QsvAv1Params

fn clone(&self) -> QsvAv1Params

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for QsvAv1Params

impl Debug for QsvAv1Params

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for QsvAv1Params

impl PartialEq for QsvAv1Params

fn eq(&self, other: &QsvAv1Params) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
