    }

    private val rtmpPusher by lazy {

    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

    }

    //无法录音

    }

    //无法调用摄像头
    override fun onVideoCaptureError(e: Exception?) {

    }

    //无法编码视频
    override fun onVideoEncoderError(e: Exception?) {

    }

    //无法编码音频
    override fun onAudioEncoderError(e: Exception?) {
        RtmpLogManager.e(TAG, "onAudioEncoderError", e)
    }

    //无法推流
    override fun onPusherError(e: Exception?) {
        RtmpLogManager.e(TAG, "onPusherError", e)
    }
