snapshot method

Future<Uint8List?> snapshot({
  1. int? width,
  2. int? height,
})

Take a snapshot for current rendered frame.

width snapshot width. if not set, result is mediaInfo.video[current_track].codec.width height snapshot height. if not set, result is mediaInfo.video[current_track].codec.height Return rgba data of image size widthxheight, stride is width*4

Implementation

Future<Uint8List?> snapshot({int? width, int? height}) {
  if (!(_snapshot?.isCompleted ?? true)) {
    _snapshot?.complete(null);
  }
  _snapshot = Completer<Uint8List?>();
  if (!Libfvp.snapshot(nativeHandle, width ?? 0, height ?? 0,
      NativeApi.postCObject.cast(), _receivePort.sendPort.nativePort)) {
    _snapshot!.complete(null);
  }
  return _snapshot!.future;
}
