createNativeStream method

Future<MediaStream?> createNativeStream()

Create a native MediaStream from processed frames

This is a placeholder for the actual implementation which would require platform channels to inject frames into a native video source.

The React equivalent is:

processedStream = mediaCanvas.captureStream(frameRate);

For Flutter, we have two options:

  1. Use MethodChannel to create native video source and inject frames
  2. Use a texture-based approach with platform views

For now, this returns the current virtual stream (may be null).

Implementation

Future<MediaStream?> createNativeStream() async {
  // TODO: Implement native MediaStream creation via platform channels
  //
  // Android implementation would:
  // 1. Create a SurfaceTexture
  // 2. Create a VideoCapturer that reads from the texture
  // 3. Create MediaStream from the capturer
  // 4. Inject frames by drawing to the texture
  //
  // iOS implementation would:
  // 1. Create a CVPixelBuffer pool
  // 2. Create RTCVideoSource from pixel buffers
  // 3. Push processed frames as CVPixelBuffers

  debugPrint(
      'VirtualStreamSource: Native stream creation not yet implemented');
  return _virtualStream;
