Struct AmfAv1Params 

pub struct AmfAv1Params {
    pub rc_mode: AmfRateControl,
    pub q_index_intra: u8,
    pub q_index_inter: u8,
    pub qvbr_quality: u8,
    pub quality_preset: AmfQualityPreset,
    pub gop_size: u32,
    pub aq_mode: u32,
    pub tiles_per_frame: u32,
}

Concrete parameters for AMD AMF AV1 (VCN on RDNA3+).

AMF is property-driven: every knob is set via AMFComponent::SetProperty(name, value) using wide-string names defined in vendor/amd/VideoEncoderAV1.h. The adapter emits integer ranges that exactly match the property-value ranges the AMF runtime accepts — out-of-range values return AMF_INVALID_ARG.

Consumed in crates/codec/src/encode/amf.rs::AmfEncoder::new.

Fields

rc_mode: AmfRateControl

AMF_VIDEO_ENCODER_AV1_RATE_CONTROL_METHOD. CQP for archive, QVBR (quality-VBR) for the common quality-target tiers.

q_index_intra: u8

AMF_VIDEO_ENCODER_AV1_Q_INDEX_INTRA. AV1 QP index 0..255 (the full AV1 quantizer range — NOT 0..63; that’s NVENC’s scale).

q_index_inter: u8

AMF_VIDEO_ENCODER_AV1_Q_INDEX_INTER. Usually +8 on intra so P-frames spend fewer bits.

qvbr_quality: u8

AMF_VIDEO_ENCODER_AV1_QVBR_QUALITY_LEVEL. 1..100 when rc_mode == QualityVbr; ignored for CQP. Higher = better.

quality_preset: AmfQualityPreset

AMF_VIDEO_ENCODER_AV1_QUALITY_PRESET. Lower = better quality.

gop_size: u32

AMF_VIDEO_ENCODER_AV1_GOP_SIZE. Frames between keyframes.

aq_mode: u32

AMF_VIDEO_ENCODER_AV1_AQ_MODE. 0=off, 1=CAQ (content-adaptive).

tiles_per_frame: u32

AMF_VIDEO_ENCODER_AV1_TILES_PER_FRAME. AMF picks the grid; we specify the total. 1 tile at ≤1080p, 4 at 1080p+, 4 at 4K (VCN is less tile-parallel than rav1e — more tiles hurts HQ).

Trait Implementations

impl Clone for AmfAv1Params

fn clone(&self) -> AmfAv1Params

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AmfAv1Params

impl Debug for AmfAv1Params

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

Formats the value using the given formatter.

impl Eq for AmfAv1Params

impl PartialEq for AmfAv1Params

fn eq(&self, other: &AmfAv1Params) -> 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.
