Since today I remarked that I couldn't play neither on-demand/live video in any Modern UI application nor HTML5 video in IE10.
Using Wireshark, I see that video URL is never called neither by the application (ISM Manifest file) nor by the browser (eg MP4). In the application, I just can see horizontal loading dots, and on this page in IE10, I see the picture but the video is never played; whereas it is working in Firefox. The following page displays blank areas.
I don't remember when video worked before today, as I didn't play anything in any application or browser (only Flash actually).
What can cause this behaviour? Is there a Relationship between Modern UI app and browser settings?
The W3 HTML5 video test page shows:
canPlayType video/ogg video/mp4 video/webm "maybe" "maybe" "probably"
canPlayType video/ogg video/mp4 video/webm "" "" ""
Here is a screen capture of my problem (I clicked through samples button under the video):
With Process Monitor, I could see some calls to Windows Media Foundation registry keys.
Is it possible to repair this component?
