camera rotation during video call - android

[Neernay Khairkar]

What steps will reproduce the problem?
1. Initiate video call between peers
2. Wait for 10 secs after call connected
3. Observe the video rotation

What is the expected result?
The video should not rotate on it owns.

What do you see instead?
Video changes orientation for a sec and come backs to normal even if the device is stationary

What version of the product are you using? On what operating system?
Git commit #12635 and Android 4.x,5.x, 6,x

Please provide any additional information below.
I have tried the following options as suggested in below links:

1. Issue 4664
setting enable_cpu_overuse_detection to false in webrtcvideoengine2.cc.

2. http://stackoverflow.com/a/32451969
setting the above boolean through mediaconstraints: googCpuOveruseDetection

FYI, the local video is good without rotation on both receiver and originator. The rotation happens on the remote video on the receiver side only.

Well, the issue is not reproducible in AppRTCDemo.

I modified the AppRTCDemo as per my SDK implementation which I am developing.

// initialized in SDK
localRender = new SurfaceViewRenderer(this);
remoteRender = new SurfaceViewRenderer(this);

// In AppRTCDemo
View mLocalView = localRender; // getting from SDK
View mRemoteView = remoteRender; // getting from SDK

localRenderLayout = (PercentFrameLayout) findViewById(R.id.local_video_layout);
localRenderLayout.addView(mLocalView);

remoteRenderLayout = (PercentFrameLayout) findViewById(R.id.remote_video_layout);
remoteRenderLayout.addView(mRemoteView);

and in updateVideoView() commenting out few properties:

// in SDK
//remoteRender.setScalingType(scalingType);
//remoteRender.setMirror(false);

//localRender.setScalingType(ScalingType.SCALE_ASPECT_FIT);
//localRender.setMirror(true);

Can you suggest where should I start looking for the video rotation? We have TAS in between the Peers.

Thanks

Have you checked your CSS?

I am on native android not on desktop or mobile browser.

[Silvia Pfeiffer]

Ah right, I just read something about apprtc and assumed, because in
browsers, the video is being inverted by CSS.

Can anyone suggest some pointers?

[Christoffer Jansson]

Could possibly be: https://bugs.chromium.org/p/webrtc/issues/detail?id=5783, have you tried latest ToT?

[Neernay Khairkar]

Yes, I have the same issue but it doesn't seems to fixed in android!

Also, I am on git commit #12979.

What is ToT? :)

And you can confirm that you have tried the latest WebRTC revision and that the issue persists?

If so, +magjed@, do you have any ideas?

[Neernay Khairkar]

yes, the issue still persist on #13125. I have opened a bug: 5971.
