Dear Klaus,
I'm having an ios/android 360 video solution running on a hybrid app's inAppBrowser. Till iOS 10 everything was fine, but as you know on iOS 10 the app was crashing.
I installed the pr7 release which runs on iOS9 and Android, but on iOS 10 the video is also opened by the native 2d video player, though I can notice that is still running in the webview too.
I made some digging and I came to the conclusion the the issue is coming from the new videoplayer.js file from pr7, since if I'm replacing it with pr6 it is working, except that has a huge lagging on iOS 10.
Could you suggest something which I could try out to block the native video player?
EDIT: I also tried the demo page from your website to open in inAppBrowser (just to eliminate eventual implementation issues), with the latest videoplayer.js it's opening in the default phone player, with pr6 version is fine.
Thanks you!
