Double vision on Samsung S7 (N+) using VrVideoView #500

Closed njudit8 closed 6 years ago

njudit8 commented 6 years ago

We are also experiencing the double vision issue described in: https://github.com/googlevr/gvr-unity-sdk/issues/421

We are using the VrVideoView from the Android SDK to display a VR video (3dh) with Cardboard. The issue only occurs on Samsung S7 (Android 7.0).

On S7, the complete 360 video is made up of only 2 views in stereo view (compared to several other devices including Samsung S6(N+), where it consists of 4 views, and there is no distortion). The video is stretched and there is a significant mismatch between left and right views, as you can see in the screenshot below. As a result, there is double-vision when viewed in Cardboard.

Changing the resolution did not solve the problem.

Thanks for looking into this. double_vision_s7

HI @njudit8, can you include which version of the SDK you're using, and which version of Google VR Services (if any) you have installed? Thanks.

njudit8 commented 6 years ago

Hi @jdduke, Google VR Services version 1.10.172754103 Google VR SDK v1.101.0 Thanks.

Updating to the latest version of Google VR Services has still not resolved the issue. Any suggestions?

Not sure if it is the same issue, but from the screenshots it looks so. I recently had similar issues happening only on S7 and S8 devices. The solution, as it turned out, had to do with a setting in Samsung devices, under Settings > Screen > Screen Resolution. Having anything other than the max resolution caused the issue.

Dropping this just in case anyone else also had this issue.

@njudit8: Are you seeing the same problem with the SimpleVideoWidget sample provided by the SDK? Have you updated your SDK to the latest 1.20.0 release? The VR Views (pano/video widgets) wouldn't necessarily be fixed by a VrCore upgrade.

@Carlos-CR Thanks! For some reason, changing the resolution to WQHD solved the issue.

@jdduke Although the bug does not appear on WQHD anymore, it is still present on lower resolutions. This is highly problematic on S7, due to another bug (switching to a lower resolution, even WQHD is shown as the set resolution). Yes, same problem with the SDK sample, and updating to the latest release did not help.

Hi @njudit8. We landed a fix in the 1.30 SDK release. Pleas give that a try, and re-open if it's still unresolved. Thanks for your patience.
