Struct NvencAv1Params 

pub struct NvencAv1Params {
    pub rc_mode: NvencRateControl,
    pub cq: u8,
    pub preset_guid: [u8; 16],
    pub tuning_info: u32,

    pub output_annex_b_format: u32,
    pub repeat_seq_hdr: u32,
}

Concrete parameters for NVENC AV1 (NV_ENC_CONFIG + NV_ENC_RC_PARAMS).

Consumed in crates/codec/src/encode/nvenc.rs when populating NV_ENC_INITIALIZE_PARAMS.encode_config (currently null — see reviews/codec-review-3.md issues 1-3).

GUID is returned as its raw 16-byte form so the caller can splat it into the SDK’s #[repr(C)] Guid { data1: u32, data2: u16, data3: u16, data4: [u8;8] } without this module depending on the FFI struct definitions.

Fields

rc_mode: NvencRateControl

Rate control mode. Values are the SDK constants NV_ENC_PARAMS_RC_CONSTQP = 0, NV_ENC_PARAMS_RC_VBR = 1, NV_ENC_PARAMS_RC_CBR = 2. We only emit CONSTQP (archive) or VBR+targetQuality (all other tiers) — CBR is never used by this service.

cq: u8

AV1 CQ target (for VBR mode) or constant QP (for CONSTQP mode). Range 0–63 for AV1 (NOT 0-51 — that range is H.264/HEVC).

preset_guid: [u8; 16]

Preset GUID raw bytes, ready to splat into a #[repr(C)] Guid. Order: data1 (4 bytes, u32 LE), data2 (2 bytes u16 LE), data3 (2 bytes u16 LE), data4 (8 raw bytes).

tuning_info: u32

NV_ENC_TUNING_INFO — always HIGH_QUALITY (1) for this service; never low-latency.

aq_strength: u8

Adaptive quantization strength 0–15. 0 disables AQ. ~8 is a reasonable default under HIGH_QUALITY tuning.

lookahead_depth: u32

Lookahead depth (frames). 0 disables. Higher = better quality bias at cost of latency.

num_tile_columns: u32

NV_ENC_CONFIG_AV1.numTileColumns.

num_tile_rows: u32

NV_ENC_CONFIG_AV1.numTileRows.

output_annex_b_format: u32

NV_ENC_CONFIG_AV1.outputAnnexBFormat. Always 0 (LOB) for MP4 muxing — AV1-ISOBMFF requires obu_has_size_field = 1.

repeat_seq_hdr: u32

NV_ENC_CONFIG_AV1.repeatSeqHdr. Always 1 so every IDR carries a sequence header for seeking.

Trait Implementations

impl Clone for NvencAv1Params

fn clone(&self) -> NvencAv1Params

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NvencAv1Params

impl Debug for NvencAv1Params

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

Formats the value using the given formatter.

impl Eq for NvencAv1Params

impl PartialEq for NvencAv1Params

fn eq(&self, other: &NvencAv1Params) -> 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.
