NoMediaResolver class final

The media-less MediaResolver: valid only for compositions that declare no media at all.

Resolving an empty source list succeeds (there is nothing to do); any actual media source is a typed failure pointing at the MediaRepository, the real resolver wired as the mediaResolverProvider default. This stays exported and is the documented choice when a composition is deliberately media-free.

Constructors

NoMediaResolver()

Creates the resolver; it is stateless and const.

const

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

bandTableFor(AudioSource source) → BandTable

The analysed BandTable for audio source — synchronous by contract, so the ReactiveScope can serve it down to the reactive effects.

override

beatGridFor(AudioSource source) → BeatGrid

The detected BeatGrid for audio source — synchronous by contract, so Trigger.beat resolves against it during timing resolution.

override

clipMetadataFor(MediaSource source) → ClipMetadata

The probed ClipMetadata of clip source — synchronous by contract, so the resampler can read its source fps and frame count during the frame loop.

override

cuesFor(CaptionSource source) → List<CaptionCue>

The parsed CaptionCues for caption source — synchronous by contract, so the caption layer can pick the active cue at the current frame.

override

decodedClipFrame(MediaSource source, int sourceFrame) → Image

The pre-decoded image of clip source at sourceFrame — synchronous by contract, so paint hands it straight to a RawImage.

override

decodedImageFor(MediaSource source) → Image

The pre-decoded image for source — synchronous by contract, so paint can hand it straight to a RawImage with no async-in-frame.

override

decodedSnapshotFor(SnapshotSource source) → Image

The pre-decoded image for snapshot source — synchronous by contract, so paint hands it straight to a RawImage with no async-in-frame.

override

materializedAudioPathFor(AudioSource source) → String

The materialized local file path for audio source — synchronous by contract, so the encode-plan builder can hand it to an audio track node.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

preResolveAll(Iterable<MediaSource> sources) → Future<void>

Resolves every source in sources (download, read, decode) so that resolvedFor and decodedImageFor can answer synchronously during the frame loop.

override

preResolveAudio(Iterable<AudioSource> sources) → Future<void>

Materializes every audio source in sources into a sandbox file the encoder can -i, validating and allowlisting each one first.

override

preResolveCaptions(CaptionSource source) → Future<void>

Reads and parses caption source into CaptionCues before the frame loop, so cuesFor can serve them synchronously during it.

override

preResolveClip(MediaSource source, Iterable<int> sourceFrames) → Future<void>

Probes source and extracts every source frame in sourceFrames, decoding each to a ui.Image cached by (source, frame) so paint can read it synchronously.

override

preResolveReactive(Iterable<AudioSource> sources, {required BeatDetectionService beatDetector, required FrequencyAnalyzer analyzer, required int fps, required int totalFrames}) → Future<void>

Analyses every reactive audio source in sources into a BeatGrid and a BandTable before the frame loop.

override

preResolveSnapshots(Iterable<SnapshotSource> sources, SnapshotService service) → Future<void>

Rasterizes every snapshot in sources through service and decodes each raster to a ui.Image cached by content hash, so decodedSnapshotFor can answer synchronously during the frame loop.

override

probeClip(MediaSource source) → Future<ClipMetadata>

Probes clip source for its ClipMetadata (fps, frame count, size) and caches it, so the render's clip pre-pass can plan which source frames to extract before calling preResolveClip.

override

resolvedFor(MediaSource source) → ResolvedMedia

The pre-resolved bytes and content hash for source — synchronous by contract.

override

toString() → String

A string representation of this object.

operator ==(Object other) → bool

The equality operator.
