cameraDirection

摄像头方向设置。详见 CAMERA_DIRECTION。

captureFormat

视频帧格式。详见 CaptureFormat。

followEncodeDimensionRatio

是否跟随 setVideoEncoderConfiguration 中设置的视频宽高比：

• true：(默认) 跟随。SDK 会将采集到的视频按照已设置的视频宽高比进行裁剪，会同步改变本地预览画面、onCaptureVideoFrame 和 onPreEncodeVideoFrame 中的视频画面。
  
• false：不跟随。SDK不改变采集到的视频帧宽高比。
