Implementations

impl VideoCodec

pub fn encoder(self) -> &'static str

The libav encoder name passed to ffmpeg -c:v.

pub fn hardware_encoder(self) -> Option<&'static str>

A second encoder to try when encoder is missing from the local ffmpeg build. Only AV1 has one — x264/x265 are universal. Apple’s hardware encoder (VideoToolbox) for this codec, if it has one.

pub fn fallback_encoder(self) -> Option<&'static str>

pub fn mp4_tag(self) -> Option<&'static str>

The -tag:v value needed for MP4 compatibility, if any.

pub fn label(self) -> &'static str

Human-readable label for output.

pub fn crf_search_bounds(self) -> (u8, u8)

Inclusive CRF range to search when targeting a VMAF score, best quality (lowest CRF) first. x265’s CRF scale is shifted ~+6 vs x264 for the same perceptual quality, and AV1’s runs 0..63 — so the bounds differ per codec.
