Configuration for IOVideoCaptureUnit.

[shogo4405]

Description & motivation

I modified the method to make it easier to perform the initial setup of IOVideoCaptureUnit when using attachCamera. You can handle it with a callback as follows.

stream.attachCamera(back, channel: 0) { videoCaptureUnit, error in
    videoCaptureUnit?.isVideoMirrored = false
    videoCaptureUnit?.preferredVideoStabilizationMode = .standard
    videoCaptureUnit?.colorFormat = kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
  if let error {
    logger.warn(error)
  }
}
