webrtc_pixel_stream #

A lightweight Flutter plugin that streams raw BGRA pixel data from WebRTC video tracks via EventChannel.

This plugin contains zero WebRTC code of its own. It depends on flutter_webrtc via CocoaPods to access the already-registered FlutterWebRTCPlugin singleton, then attaches a secondary RTCVideoRenderer to any video track to extract raw frames.

Usage #

This plugin is used internally by aura_sphere_360 for native WebRTC pixel extraction. You typically don't need to use it directly.

How it works #

1. Dart calls createPixelStream on the webrtc_pixel_stream/control method channel
2. Native code looks up the video track via FlutterWebRTCPlugin.sharedSingleton
3. A FlutterRTCStreamingSink (RTCVideoRenderer) is attached to the track
4. I420 frames are converted to BGRA and streamed over webrtc_pixel_stream/frames/{trackId}

Platform support #

Requirements #

• flutter_webrtc must be initialized before calling createPixelStream
• iOS 13.0+
