miniav_tools_platform_interface 0.5.5

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

Changelog

0.5.5

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

0.5.4

• Documentation only: the colour-contract doc comment no longer names a private downstream project. No API or behaviour change.

0.5.3

• PlatformEncoder gains two GPU-input capability getters, both defaulting to false: supportsD3d11SharedHandleInput (a FrameSource.miniavBuffer whose nativeHandles[0] is a D3D11 shared NT handle, opened on the encoder's own device) and supportsD3d11TextureInput (a D3D11TextureFrameSource — a raw texture pointer on the processor's device, so strictly stronger). They let the recorder pick its zero-copy screen path by capability instead of by concrete encoder type. Implementers use implements PlatformEncoder, so these must be declared explicitly — the defaults do not carry.

• Audio decode contract (the supportsAudioDecode() capability existed with no factory): PlatformAudioDecoder, DecodedAudio (interleaved f32), AudioDecoderConfig, and MiniAVToolsBackend.createAudioDecoder (default null — non-breaking for existing backends).

• Demuxer stream support (for miniav_player stream/file playback): DemuxerInput.byteStream(Stream<List<int>>) (StreamDemuxerInput) for live/progressive containers; PlatformDemuxer.durationUs (nullable) and PlatformDemuxer.isSeekable (both default no-op → non-breaking). Packet trackIndex on demuxer output indexes into tracks.

• DecodedFrame.webVideoFrame (Object?, default null) — an already-presentable browser VideoFrame handle for the web WebCodecs decode path (presented directly, no readback). Native implements DecodedFrame classes 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

• Add CpuExecutor — a platform-agnostic seam for running CPU-bound work off the main isolate. Native (dart:io) uses a long-lived background Isolate reused across calls; web (dart:js_interop) runs inline (browser already threads the codec/GPU paths). Resolved via conditional import so dart:isolate never reaches web builds (verified with dart compile js). Intended for the pure-Dart CPU hotspots that have no native thread to hide behind (software pixel conversion fallback, AV1 entropy coder).
• Add FrameSource.yuv420p — a pre-converted planar YUV420P (I420) frame source (three tightly-packed u8 planes), so a GPU color-conversion step can feed an encoder directly with no further conversion.
• Add PlatformEncoder.acceptsYuv420pPlanes (default false) so the recorder can detect encoders that consume YUV420P planes natively.
