One of our client reported that its always crashing when video call arise. We are showing local video on screen until user accept the call.

private void createAudioAndVideoTracks() {
        Logg("createAudioAndVideoTracks called!!!");
        // Share your microphone
        localAudioTrack = LocalAudioTrack.create(this, true, LOCAL_AUDIO_TRACK_NAME);

        // Share your camera
        cameraCapturer = new CameraCapturer(this, CameraCapturer.CameraSource.FRONT_CAMERA);
        localVideoTrack = LocalVideoTrack.create(this, true, cameraCapturer);
        primaryVideoView.setMirror(true);
        localVideoTrack.addRenderer(primaryVideoView);
        localVideoView = primaryVideoView;

        /*
         * Set the initial state of the UI
         */
        intializeUI();
    }

Note: Device camera is working fine both front and back camera.

What would be the exact issue for causing this crash?

@aaalaniz can you help here

Hey @Balasnest

Thanks for filing this issue!

Typically we have seen this issue occur when a device does not have a front or back camera available. The CameraCapturer API provides a static method isSourceAvailable that will check for the availability of a particular source. At first glance, I have no reason to believe that the Redmi 4A does not have a front camera though.

We have a Xiaomi MI 5s that we can test with. This may be a bug in the isSourceAvailable API. I will investigate and report back.

Thanks!

@aaalaniz Thanks for your quick reply. I have checked with the user. He stated that both side camera is working flawlessly in WhatsApp.

@Balasnest We have recently cut a new release, 5.1.0, and believe it will fix the issue you are experiencing. Please let us know if you are still running into any issues when using the new release. Thanks!

@Alton09 I'm working with the Camera2 API and was wondering if we could get support for LEGACY mode as the product we would like to use it on will not require any special cropping. Thanks!
