isSupported property

bool get isSupported

Check if native virtual background is supported on this platform.

Supported platforms:

• Android: Has LocalVideoTrack.ExternalVideoFrameProcessing interface + MediaPipe
• iOS: Has VideoProcessingAdapter + Vision framework for segmentation
• macOS: Has VideoProcessingAdapter + Vision framework (requires macOS 12.0+)
• Windows: Disabled — libwebrtc RTCVideoSource has no PushFrame API and WGC refuses to capture programmatic popup windows.
• Linux: flutter_webrtc C++ layer lacks video processing hooks
• Web: Would need different approach (not native)

Implementation

static bool get isSupported {
  if (kIsWeb) return false;
  return Platform.isAndroid ||
      Platform.isIOS ||
      Platform.isMacOS;
}
