Struct PassthroughTranscoderFactory 

pub struct PassthroughTranscoderFactory { /* private fields */ }

Factory that builds a PassthroughTranscoder for each video-track source stream a crate::TranscodeRunner sees.

Constructed with a single RenditionSpec; register N factory instances on the runner (typically three, one per rung of RenditionSpec::default_ladder) to scaffold an ABR ladder’s observability without the gstreamer dep.

Implementations

impl PassthroughTranscoderFactory

pub fn new(rendition: RenditionSpec) -> Self

Build a factory for the supplied rendition.

Trait Implementations

impl TranscoderFactory for PassthroughTranscoderFactory

fn name(&self) -> &str

Stable identifier used in metric labels and logs (e.g. "passthrough", "x264", "nvenc"). Pick something short, lowercase, snake_case.

fn rendition(&self) -> &RenditionSpec

Target rendition this factory produces. Consumed by the crate::TranscodeRunner when building the TranscoderContext.

fn build(&self, ctx: &TranscoderContext) -> Option<Box<dyn Transcoder>>

Build a fresh transcoder for ctx, or return None to skip this (broadcast, track) entirely. Returning None is the correct path when the factory wants to opt out – e.g. a video transcoder returning None for an audio track, or a factory targeting only source broadcasts (not already-transcoded renditions).
