I cannot seem to get HTML5 video working in IE11 on Server 2012 R2, in RDSH mode (Remote Desktop Session Host).
I have the Desktop Experience feature installed, and have tried adding the sites (e.g. youtube, vimeo) to trusted sites and cranked the security down to the lowest (medium-low) for trusted sites but nothing. I don't really want to have to use trusted sites anyway...
On YouTube I am getting the HTML5 right-click menu over the video area, but no video plays - just a buffering symbol spinning and then a black area where the video should be.
I tried changing the user agent to IE10 via the F12 tools, but no change.
I ran the suite of tests from peacekeeper.futuremark.com and most of the stuff worked, e.g. all the animations, but none of the video, especially videoCodecH264 showed as N/A.
www.w3.org/2010/05/video/mediaevents.html is giving "unknown error" in the video playback window.
I can make YouTube work by adding it to compatibility view, where it then drops back to using Flash player. This does not work for Vimeo.
I have minimal policy settings set on these servers at the moment.
Any suggestions would be most welcome, thanks in advance.
