WebAudioFallbackBackend class
- Inheritance

- Object
- MiniAVToolsBackend
- WebAudioFallbackBackend
Constructors
Properties
-
acceptedFrameSources
→ Set<
FrameSourceKind> -
Which FrameSource variants this backend can consume directly (without
the facade falling back to CPU readback).
no setteroverride
- hashCode → int
-
The hash code for this object.
no setterinherited
- name → String
-
Human-readable backend name, e.g.
"ffmpeg","webcodecs","minigpu".no setteroverride - priority → int
-
Higher value = preferred when multiple backends support the same codec.
Backends should default to 0 and let users override via
MiniAVToolsPlatform.setBackendPriority.
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
createAudioDecoder(
AudioDecoderConfig config, {BackendContext? context}) → Future< PlatformAudioDecoder?> -
Construct an audio decoder. Default implementation returns
null— backends without audio support don't need to override.override -
createAudioEncoder(
AudioEncoderConfig config, {BackendContext? context}) → Future< PlatformAudioEncoder?> -
Construct an audio encoder. Default implementation returns
null— backends without audio support don't need to override.override -
createDecoder(
DecoderConfig config, {BackendContext? context}) → Future< PlatformDecoder?> -
override
-
createDemuxer(
DemuxerConfig config) → Future< PlatformDemuxer?> -
override
-
createEncoder(
EncoderConfig config, {BackendContext? context}) → Future< PlatformEncoder?> -
override
-
createMuxer(
MuxerConfig config) → Future< PlatformMuxer?> -
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

-
probe(
CodecQuery query) → Future< List< CodecCapability> > -
Enumerate the concrete CodecCapabilitys this backend offers for
query.inherited -

-
toString(
) → String -
