    /**
     * 1, autoCallProximity: 语音通话时使用, 距离感应自动黑屏
     * 2, videoCropRatio: 制定固定的画面裁剪比例，发送端有效
     * 3, videoAutoRotate: 结合自己设备角度和对方设备角度自动旋转画面
     * 4, serverRecordAudio: 需要服务器录制语音, 同时需要 APP KEY 下面开通了服务器录制功能
     * 5, serverRecordVideo: 需要服务器录制视频, 同时需要 APP KEY 下面开通了服务器录制功能
     * 7, videoQuality: 视频质量调整, 最高建议使用480P
     * 8, videoFpsReported: 是否开启视频绘制帧率汇报
     * 9, deviceDefaultRotation: 99.99%情况下你不需要设置这个参数, 当设备固定在水平方向时,并且设备不会移动, 这时是无法确定设备角度的,可以设置一个默认角度
     * 10, deviceRotationOffset: 99.99%情况下你不需要设置这个参数, 当你的设备传感器获取的角度永远偏移固定值时设置,用于修正旋转角度
     * 11, videoMaxBitrate: 视频最大码率设置, 100K ~ 5M. 如果没有特殊需求不要去设置,会影响SDK内部的调节机制
     * 12, audioEffectAecMode: 语音处理选择, 默认使用平台内置,当你发现平台内置不好用时可以设置到SDK内置
     * 13, audioEffectNsMode: 语音处理选择, 默认使用平台内置,当你发现平台内置不好用时可以设置到SDK内置
     * 14, videoHwEncoderMode: 视频编码类型, 默认情况下不用设置.
     * 15, videoHwDecoderMode: 视频解码类型, 默认情况下不用设置.
     * 16, audioHighQuality: 高清语音，采用更高的采样率来传输语音
     * 17, audioDtx: 非连续发送，当监测到人声非活跃状态时减少数据包的发送
