Future<(bool, Mat)> readAsync({
  1. Mat? m,

Implementation

  m ??= Mat.empty();
  final p = calloc<ffi.Bool>();
  return cvRunAsync0(
    (callback) => cvideoio.cv_VideoCapture_read(ref, m!.ref, p, callback),
    (c) {
      final rval = (p.value, m!);
      calloc.free(p);
      return c.complete(rval);
    },
