Module codec

Structs§

AudioDrain: Packets and metadata emitted while draining an audio encoder.
AudioEncoderConfig: Backend-neutral audio encoder configuration.
AudioEncoderFormat: Audio format accepted by an audio encoder.
AudioGapless: Gapless audio metadata produced when an encoder is drained.
CancellationToken: A cheap cloneable cancellation signal shared with a running codec operation.
DecodeStatistics: Observable counters for validating cache and decoder reuse behavior.
DecodedVideoFrame: One normalized decoder output, independent of backend-private image types.
EncodedSample: One encoded access unit with exact decode and presentation timing.
EncodedVideoSample: One owned compressed sample in decode order with its presentation identity.
EncoderConfig: Codec and sample-entry information needed to declare an MP4 track.
ExactFrameReader: Presentation-indexed exact-frame access over decode-order compressed samples.
SampleDependency: Dependency information written to the MP4 sample dependency table.
VideoDecoderConfig: Backend-neutral video decoder configuration.
VideoEncoderConfig: Backend-neutral video encoder configuration.
VideoEncoderFormat: Video format accepted by a video encoder.

CodecImplementation: The implementation class selected by a codec factory.
CodecProfile: A normalized codec profile that can be compared across backend implementations.
CodecSupport: The result of querying a factory with a complete normalized configuration.
HardwarePreference: Whether a caller permits or requires a hardware codec implementation.
Seek: What a constant-time ExactFrameReader::seek could answer with.
TrackKind: The kind of media carried by an encoded track.

SEEK_LATENCY_BUDGET: The longest a seek to any position of any track may take.

AudioEncoder: Backend-neutral audio encoder contract.
AudioEncoderFactory: Discovers and creates audio encoders using the normalized capability model, the audio counterpart to VideoEncoderFactory.
SeekPreviewSource: Already-decoded pictures spread over a track, which a seek may answer from.
VideoDecoder: A stateful video decoder that may retain reference and reorder state.
VideoDecoderFactory: Discovers and creates video decoders without exposing backend-specific types.
VideoEncoder: Backend-neutral video encoder contract.
VideoEncoderFactory: Discovers and creates video encoders using the normalized capability model.

uncompressed_video_decoder_factory: Returns the portable, software-only uncompressed Gray8 decoder backend.

EncoderFuture: A non-Send encoder future that works on native and single-threaded WASM.
