Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36 Example URL: Steps to reproduce the problem: 1. Play a youtube video 2. Watch CPU Usage 3. What is the expected behavior? Low CPU usage What went wrong? Very High CPU usage Did this work before? N/A Is it a problem with Flash or HTML5? N/A Does this work in other browsers? N/A Chrome version: 50.0.2661.94 Channel: stable OS Version: 6.1 (Windows 7, Windows Server 2008 R2) Flash Version: Shockwave Flash 21.0 r0 Since youtube use the VP9 codec and 60 fps video (720p and 1080p), it uses a lot of CPU. In firefox, version 46, it checks if the CPU is good enough to activate or not the VP9 codec. In chrome, it's always VP9. It will be good if chrome would do the same thing as Firefox. I want to buy a new laptop, this issue concern me because I want to watch at least 720p 60 fps videos on youtube. Is a I3 4005u is sufficent to play that ? Thanks

I made a couple of other tests. The major problem is 60 FPS videos on YouTube. Vp9 takes more CPU than h264, but at 30 fps, CPU usage is still low. But at 60 fps, it literally double the CPU usage and I get a lot of frame drop. The only option with 60 fps videos, is to select 480p to have it at 30 fps. We need at least 720p 30 fps. It needs a core I7 on a laptop to be able to play a video in 60 fps using VP9.
