Struct Config 

#[non_exhaustive]
pub struct Config {
    pub rungs: Vec<Rung>,
    pub source: Option<PathRelativeOwned>,
    pub encoder: Kind,
    pub decoder: Kind,
}

Transcoder configuration for run.

#[non_exhaustive]: build via Config::default() and set fields, so future knobs don’t break callers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rungs: Vec<Rung>

Candidate output renditions. Only rungs strictly below the source survive: a rung is dropped when its height exceeds the source, when its bitrate is not below the source bitrate (when known), or when it matches the source height without a known source bitrate to undercut. A 480p source is never transcoded up to 720p.

source: Option<PathRelativeOwned>

Where the source broadcast lives relative to the output broadcast, e.g. ".." when the output is published at <source>/transcode.hang. When set, the derivative catalog references the source renditions (all video and audio) through this path so players fetch them from the source directly; the transcoder never proxies or subscribes them. None omits them from the derivative catalog.

encoder: Kind

Which video encoder implementation encodes the rungs. The default prefers hardware (NVENC on Linux, VideoToolbox on macOS, Media Foundation on Windows) and falls back to openh264.

decoder: Kind

Which video decoder implementation decodes the source. The default prefers hardware and falls back to openh264 (H.264 only; H.265 sources need a hardware decoder).

Trait Implementations

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.
