Currently I cannot play video from Twitter, Twitter show "This browser does not support playback video".
And this test page (http://www.quirksmode.org/html5/tests/video.html) I also cannot play H.264/MP4

I can play video on web normal with other browsers as Edge, Firefox and Chrome.

I am using Windows 10 x64 with Opera 32
