miniav_platform_interface 0.8.0

A platform interface for the miniav library, allowing for different implementations.

miniav_platform_interface CHANGELOG

0.8.0

• Screen frames can say which parts changed: MiniAVVideoBuffer.damage (MiniAVVideoDamage, MiniAVDamageRect) holds a frame's changed rectangles when the backend can certify them. Partial damage is relative only to the frame delivered just before it in the same sourceEpoch; a gap in generation, a size change, fullFrame or null means the whole frame.
• MiniScreenContextPlatformInterface gains four members. Their defaults report "unsupported" and leave the capture alone:
  • setCaptureFrameRate(fps) changes the selected source's rate without opening the picker again.
  • setContentHint(hint) sets the selected video track's content hint.
  • fallbackToCpuDelivery() switches a live capture to CPU frames without reacquiring its source.
  • cpuDeliverySurface is the surface CPU delivery draws into, when the backend can expose it without a copy. The context keeps ownership.
• Video frames can say how their YUV is coded: MiniAVVideoBuffer.color (MiniAVVideoColor: a MiniAVYuvMatrix of BT.601, BT.709 or BT.2020, and full or limited range). It is null when the backend does not say: RGB formats, screen capture, and for now every camera backend except Windows.

0.7.4

• Increment downstream deps

0.7.3

• New MiniAVBufferContentType.gpuWebVideoFrame: a WebCodecs VideoFrame in nativeHandles[0], with no CPU planes. Release it with releaseBuffer, which closes it; unclosed frames make the browser's track processor stop producing, with no error.
• New openCaptureMirror / closeCaptureMirror on the audio-input interface, with MiniAVCaptureMirrorHandle describing where a capture mirror lives in a form that can cross threads. Null where the platform has none.

0.7.2

• released 08/13/26 - MR

0.7.1

• Version bump so the family can depend on miniav_ffi 0.7.1 (Windows camera and COM/MF fixes). No API change in this package.

0.7.0

• The GPU buffer handoff contract is documented on its types: MiniAVBufferContentType tells CPU from GPU frames (planes[0] is empty on the GPU path); MiniAVVideoBuffer.nativeHandles[0] holds the Windows shared NT handle, which miniav closes on buffer release; and MiniAVNativeFence is unimplemented, its fields always holding their sentinel values.
• MiniScreenPlatformInterface.setIOSAppGroup(String) registers the App Group for iOS system-wide broadcast capture; the default throws UnsupportedError.

0.6.0

0.5.11

0.5.10

0.5.9

• Add releaseBufferSync() to MiniAVPlatformInterface, defaulting to releaseBuffer(); backends with a synchronous release should override it.

0.5.7

• Fix logger noisiness

0.5.6

• Fix a FormatException on non-UTF-8 bytes in the MiniAV log callback.
• Add setLogCallback (a no-op by default) and installStderrLogger to route native MiniAV log lines to a Dart callback.

0.5.5

• fix wasapi loopback issue

0.5.4

• adds bindings observer lib to fix crash on hot restart

0.5.3

• Fix crash bug on hot refresh, fix crash on second use of recorder

0.5.2

• adds shared textures

0.5.1

• adds subscriptions and fixes lost device crashes
