createNativeStream method
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:
- Use MethodChannel to create native video source and inject frames
- 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
