When toggling WebVR on iPhone, an empty video shows up

Question

I've got a problem with a vtour generated from KRPano 1.19-pr16 when clicking on the VR icon on iPhone.

The vTour has simply been generated via the droplet and a static 360 image and encapsulated in Cordova. On any browser, clicking the VR icon toggles the WebVR on and that's it.

On iPhones, an empty video displays when I tap on the VR icon and I have to close the said video before accessing VR. Is there a way to avoid this ?

Answer 1

For anyone wondering why a video shows up and how to avoid this, here's the official forum post where Klaus answered me

that's the 'ios wakelock' hack - it play a 'hidden' video in the background to avoid that Safari would let the device go into sleep mode.

There are two solutions for custom apps (both should be applied):

Enable the 'allowsInlineMediaPlayback' setting in your app: https://developer.apple.com/documentatio…nemediaplayback This would avoid that the browser would open the build-in fullscreen videoplayer when playing the 'wakelock' video.

And better also disable the 'wakelock' hack of the krpano WebVR plugin: https://krpano.com/plugins/webvr/#mobilevr_wakelock and disable the device-sleep-mode directly in your app.
