Crash when outgoing video call

[SmartSystemElectronics]

In my codes, when I create call and after previewing video start, it will be crash.

Crash is happening in this line -->> currentCall.vidPrev.start(vidPrevParam);

    if (currentCall != null && currentCall.vidWin != null && currentCall.vidPrev != null) {
            try {
                epGlobal.libRegisterThread("videocall");
            } catch (Exception e) {
                e.printStackTrace();
            }

            VideoWindowHandle vidWH = new VideoWindowHandle();
            vidWH.getHandle().setWindow(holder.getSurface());
            VideoPreviewOpParam vidPrevParam = new VideoPreviewOpParam();
            vidPrevParam.setWindow(vidWH);

            try {
                currentCall.vidPrev.start(vidPrevParam);
            } catch (Exception e) {
                e.printStackTrace();
                Log.e(TAG,"error in starting video: " + e.getLocalizedMessage());
            }
    } 

The error logs are here;

I can create voice call successfully, but in the other hand I cannot with video. Can you anyone help me?

Have you set the camera manager? Which version of the lib are you using? Have you tried not registering a dedicated thread for videocall? Have you tried just doing things like in the startPreviewVideoFeed method ?

1 - I didn't set and I dont know how to and when set camera manager 2 - 4.0.2 3 - I registered my video call with libregisterthread(); 4 - Yeah, as you can see, the method I use is same with yours startPreviewVideoFeed.

On the other hand, callMediaInfo.getVideoIncomingWindowId() returns -1, why?

1. SipServiceCommand.setCameraManager(getSystemService(Context.CAMERA_SERVICE) as CameraManager)
2. what? pjsip-android latest version is 2.9.3
3. yeah I see that, you sould try NOT to register a dedicated thread
4. if it was the same you wouldn't have registered a dedicated thread

2. how do u integrate the lib in your app? Either you have set the version in the github dependency version string, or if you cloned the repo in yuour project, you can read the app/build.gradle file to check the version
