Hi,
I have installed the Chrome extension h264ify into Opera to switch from VP9 to h264 video format in the YouTube HTML5 video player so I could benefit from GPU video decoding.
In Chrome (with h264ify uinstalled), when I start an YouTube video, I can see in the Chrome task manager the tab with the video drains 10-20% of CPU whereas in Opera the same video drains 50-60% of CPU.
The #disable-accelerated-video-decode feature in opera://flags special page is set to its default disabled state. On the opera://gpu special page there's Video Decode: Hardware accelerated line. When clicking on the statistics for experts button in the HTML5 video player it says it uses AVC for a codec.
Where's the problem? Is it a bug? Thanks.
