OnLocalVideoInit 在什么时候调用

OnLocalVideoInit 没调用直接崩溃

-[AnyChat -[AnyChatDemo.VideoViewController OnLocalVideoInit:]: unrecognized selector sent to instance 0x103c533c0Demo.VideoViewController OnLocalVideoInit:]: unrecognized selector sent to instance 0x103c533c0

您可以发下我们的日志来分析下，您函数调用顺序是否有问题，另外您可以先直接跑下我们的demo看看是否正常。另外您可以参考我们的demo，调用UserCameraControl打开视频，调用UserSpeakControl打开音频。执行此操作之后，会自动调用OnLocalVideoInit方法

没有什么分析日志

我是对照你的demo写的，VideoViewController是复制你们的

    func startVideoChat(_ userID: Int32) {
        
        // 枚举本地视频采集设备
        let videoDeviceArr = AnyChatPlatform.enumVideoCapture()
        // 选择指定的视频采集设备
        if videoDeviceArr!.count > 1 {
            // 前置摄像头
            AnyChatPlatform.selectVideoCapture(videoDeviceArr!.object(at: 1) as! String)
        }
        // 本地设置
        AnyChatPlatform.setSDKOptionInt(BRAC_SO_LOCALVIDEO_OVERLAY, 1)
        AnyChatPlatform.setSDKOptionInt(BRAC_SO_LOCALVIDEO_ORIENTATION, Int32(self.interfaceOrientation.rawValue))
        // 采用 Overlay 模式
        AnyChatPlatform.userSpeakControl(-1, true)
        AnyChatPlatform.setVideoPos(-1, self, 0, 0, 0, 0)
        AnyChatPlatform.userCameraControl(-1, true)
        
        // 远程方设置
        AnyChatPlatform.userSpeakControl(userID, true)
        AnyChatPlatform.setVideoPos(userID, self.remoteVideoSurface, 0, 0, 0, 0)
        AnyChatPlatform.userCameraControl(userID, true)
        
    }

OnLocalVideoInit  您实现的这部分 代码是否不对，照着我们demo抄吧。另外您有没有写这个回调？建议您先调试我们demo跑跑debug下

liu

关键这个OnLocalVideoInit方法没有走

    //创建和初始化 AVCaptureVideoPreviewLayer 对象,实现本地视频的显示
    func OnLocalVideoInit(_ session: AVCaptureSession) {
        self.localCaptureLayer = AVCaptureVideoPreviewLayer(session: session)
        self.localCaptureLayer!.frame = CGRect.init(x: 0, y: 0, width: 100, height: 130)
        self.localCaptureLayer!.videoGravity = AVLayerVideoGravity.resizeAspectFill
        self.localVideoView.layer.addSublayer(self.localCaptureLayer!)
    }

请对比下我们的demo与您编写及相关引用之间的区别。
