Very slow video rendering performance. #103

Closed ghost closed 8 years ago

ghost commented 8 years ago

Initially the video plays in an expected framerate, all fine so far..

-> After going in fullscreen-mode and then switching several times between fullscreen-mode and cardboard-mode, the framerate of the video downgrades dramatically ( like 3 frames every 5 seconds ).

Tested on multiple devices (iPhone 5s and iPhone 6) width different video-sources ( both in mono mode, 1080p and 720p ) Video-Files are stored locally on the device itself. No memory issues, no CPU issues.

Would be great if you guys could provide some support there.

Best, S.

Update: It turned out that disabling "enableFullscreenButton" on the videoView did the trick.

S, what version of the SDK are you using?

Abhishek, please stop hijacking other people's threads and create a thread with your own issues.

Any progress here? Could you guys reproduce this issue on ios? It's still existing when the user often switches between cardboard-fullscreen-view ( _videoView.displayMode = 3; ) and back to normal view. And again and again.

Would be nice if someone could help me out.

Best, S.

We haven't been able to repro this yet, but we are trying.
