Module stream 

Stream metadata shared between containers and codecs.

Structs

CodecId

A stable identifier for a codec. Codec crates register a CodecId so the codec registry can look them up by name.

CodecParameters

Codec-level parameters shared between demuxer/muxer and en/decoder.

NullCodecResolver

Null resolver that resolves nothing — useful as a default when a caller doesn’t have a real registry handy (e.g. unit tests, or legacy callers of the tag-free open() APIs).

ProbeContext

Context passed to a codec’s probe function during tag resolution.

StreamInfo

Description of a single stream inside a container.

Enums

CodecTag

A codec identifier scoped to a container format — the thing a demuxer reads out of the file to name a codec. Resolved to a CodecId by the codec registry.

Traits

CodecResolver

Resolve a CodecTag (FourCC / WAVEFORMATEX / Matroska id / …) to a CodecId. The oxideav-codec registry implements this, but defining the trait here lets containers consume tag resolution via &dyn CodecResolver without pulling in the codec crate as a direct dependency.

Type Aliases

Confidence

Confidence value returned by a probe. 1.0 means “certainly me”, 0.0 means “not me”, values in between mean “partial evidence — if no higher-confidence claim exists, this should win”. The registry picks the claim with the highest returned confidence and skips any that return 0.0.

ProbeFn

A probe function a codec attaches to its registration to disambiguate tag collisions. Called once per candidate registration during resolve_tag.
