WebView crashes on Video playback #13

Closed dereulenspiegel closed 9 years ago

dereulenspiegel commented 10 years ago

First of all, I think it is really great that someone is finally building an usable WebView fore pre-KitKat devices. I already started implementing a first app with this WebView. But while most of the pages render perfectly and even complex HTML5 apps are executed perfectly one of my main use cases is the playback of HTML5 video. A quick test with loading youtube videos unfortunately crashed my app. Here is the stack trace:

I hope you can give me hint how to play back HTML5 videos with your WebView.
