Youtube and VP9 CPU decoder

Playing youtube videos by default will use VP9 video decoder, however most computers do not have hardware support for VP9, so CPU decoding is used instead. This leads to high CPU/RAM usage, low batte...

Hello, Sorry to bump an old issue.

I have been using internet explorer and then edge for mostly video playback. Both of them played youtube video very fine. However, the new edge is using a lot of cpu usage on a core-i5 6200u. Yes the chrome also use similar cpu usage. Let me give a simple scenario for a 1080p 60fps youtube video.

Edge (1-3%)

Chome (15-18%)

Edge New (20-22%)

Firefox (20-25%)

..Core-i56200u, 8GB Ram, Windows 10 1903.

 

I sure hope that edge will continue to add new features and provide the fallback video codec feature in settings like the old one.

Hi, I'm facing the exact same problem to yours.
My specs: i5-6300u, 8gb of ram, no dedicated graphic card, windows 10.
When i play 1080p60 youtube video on chrome, my total cpu usage is around 50-60%. That makes my laptop's temp uneccessarily increasing.
But I see that in the same scenario your chrome cpu usagei is just 15-18%, is that correct?

    Microsoft never added support for h264 fallback like the old one. However, you can use the enhanced-h264ify plugin (Chrome, Edge, Firefox) to resolve the issue. Back to cpu usage of 2-3% on most of the videos.
    Yes, with 6200u and NVidia 940mx I got 15-20% CPU usage. I think e-gpu is irrelevant here as it doesn't kick in for browsers.
    The newer cpu has vp9 decoder and wont have this issue though.
