miniav_tools_platform_interface 0.6.2

Platform interface for miniav_tools, providing codec/container types and abstract backend contracts.

Changelog

0.6.2

• Version bump for the miniav_tools 0.6.2 family. No functional change in this package.

0.6.1

• Requires spawn ^0.1.2.

0.6.0

• New FrameRepeatingEncoder, for a video encoder that can re-submit the last frame it accepted under a new timestamp. Re-submitting the producer's surface could read the next picture, so the duplicate showed newer content than the frame after it and playback jumped backwards. repeatLastFrame returns a packet as encode does; an encoder whose packets do not carry their frame's timestamp throws when it has nothing to repeat, so a caller pairing packets with frames stays in step.
• FrameSource.miniavBuffer takes an optional timestampUs that replaces the buffer's own, so a buffer submitted twice carries its own time.
• Requires miniav_platform_interface 0.8.0.

0.5.8

• Requires spawn ^0.1.1: native transfers actually transfer, and a web message the worker cannot deserialize is reported instead of vanishing.

0.5.7

• Increment downstream deps

0.5.6

• Exports the audio-ring cursor primitives, so a ring with its own layout (miniAV's capture mirror) can reuse their memory ordering. gpuWebVideoFrame buffers map to the webVideoFrame frame source kind.

0.5.5

• New SharedAudioRing: a lock-free single-producer/single-consumer ring of interleaved f32 PCM in shared memory, so decoded audio reaches an audio thread without passing through the main thread. Adds the demux wire protocol shared by worker-hosted demuxers.

0.5.4

• Documentation fix only; no API or behaviour change.

0.5.3

• PlatformEncoder gains supportsD3d11SharedHandleInput (a FrameSource.miniavBuffer whose nativeHandles[0] is a D3D11 shared NT handle) and supportsD3d11TextureInput (a D3D11TextureFrameSource on the producer's own device), both false by default, so the recorder picks its zero-copy path by capability. Classes that implements PlatformEncoder must declare both.
• Audio decoding: PlatformAudioDecoder, DecodedAudio (interleaved f32), AudioDecoderConfig and MiniAVToolsBackend.createAudioDecoder (default null, so existing backends are unaffected).
• Demuxer streams: DemuxerInput.byteStream(Stream<List<int>>) (StreamDemuxerInput) for live or progressive containers, plus PlatformDemuxer.durationUs (nullable) and isSeekable, both with defaults. A demuxed packet's trackIndex indexes into tracks.
• DecodedFrame.webVideoFrame (Object?, default null): a browser VideoFrame ready to present, from WebCodecs decoding on web. Native classes that implements DecodedFrame must return null.

0.5.2

0.5.1

0.5.0

• Version bump to keep the miniav_tools family in lockstep; no changes in this package.

0.4.10

• New CpuExecutor runs CPU-bound work off the main isolate: on a long-lived background isolate natively, inline on web, without dart:isolate reaching web builds.
• New FrameSource.yuv420p: a planar YUV420P (I420) frame source, so a GPU colour conversion can feed an encoder directly.
• New PlatformEncoder.acceptsYuv420pPlanes (default false) for encoders that take YUV420P planes natively.
