[Samsung Gear VR] Is it possible to freeze any camera rotations without jitters ?

[Anonymous]

Hello everybody,

I'm currently developping a native android
application for Samsung Gear VR that is basically a 360 video player (It
uses exoplayer2).

I would like to completely disable the
camera's rotations in order to force the user to see only a fixed part
of the 360 video (no matter where he wants to gaze).
To do this, I
changed the cameraRigType of my mainCamera to the Freeze type.
(http://www.gearvrf.org/api_reference/v4.1/Framework/org/gearvrf/GVRCameraRig.GVRCameraRigType.Freeze.html)

But
the results I get are not as expected. Yes the camera is now froze, but
when the phone is rotating, some video jitters appears and they are very
discomforting. Why ?
Is there a way to avoid this jitters ?
Do exist some methods that i could use to ignore all IMU inputs ?

In
the documentation it says that changing the type of the cameraRig
changes the way the rig uses the rotation data of the sensors.

Do you know which class does send this rotation data to the camera rig ?

Thank you for the reading,

I'm here if you need any precisions.

I've tested to freeze the camera using the same method on gvr-photo360, and there is no flickering at all !

So I think this is related to my application, maybe exoplayer ? My version of exoplayer is r2.4.0.

I'm currently trying to test it on gvr-video360.

I'll keep you updated.

Finally I've updated the version of the gear framework from 3.2 to 4.1.0-SNAPSHOT in the build.gradle and it works properly !
