Html5 h264 video hardware acceleration not working
Firefox nightly 45.0a1; Windows 10; Direct2D Enabled: true; Video example: https://www.youtube.com/watch?v=5CCOkiaqL0g
Firefox doesn't use hardware acceleration for html5 h264 codec videos. Cuz of that i got 100% CPU usage and freezing video playback. Chrome or Edge has about 15% CPU usage on same videos and smooth playback. Is it possible to fix it by myself or is it software bug?

Hi alez could you first check if the hardware acceleration is checked in:
about:preferences#advanced (type this in address bar) and see if "use hardware acceleration when possible" is checked. ______________________ Also, could you take a screenshot from : https://www.youtube.com/html5 ______________________ Are you using flash player or html5 to watch youtube?

"Use hardware acceleration when available" is checked. ______________________ "https://www.youtube.com/html5" everything is supported besides "MSE & WebM VP9 " ______________________ i'm using html5 player with h264 codec, not vp9.
Found that firefox modification https://pcxfirefox.wordpress.com/ Works like a charm! So it is a software bug in current firefox version.
