<![CDATA[High cpu usage watching youtube]]>Hi, since I updated from version 63 to 64 watching videos on youtube is high CPU usage. In version 63 it was 30% now in version 64 it is 60% - 70%.
I found in Changelog Opera 64

DNA-79675 Use FFmpegDemuxer to demux MP4 + H.264 + AAC

And some other entries from FFmpegDemuxer
However, this flag is disabled and enabling it will do nothing.

Anyone know what happened that from version 63 to version 64 will give more CPU usage when watching videos?

Make sure hardware acceleration is enabled or this won't work
(If you can't find hardware acc, go here opera://settings and type in "hardware acceleration")
Go to opera://flags/#ignore-gpu-blocklist
Enable that setting, relaunch and you should be good.

Thankyou! This worked for me, current 89.0.447.83 W10 64 bit - years after this thread began!

Thing is, for years I've had no trouble, until about 3 weeks ago. I could have 40 tabs open and still play YouTube. Since when it deteriorated to the point where just one tab would drop frames and eventually stall using 100% CPU.

Clearing cache and a restart would then be needed before I could browse anything

Your fixes worked - although I still note load is halved if I hover over the You Tube animated tab. Alas I can find no setting or flag to fix that in the current version.

You're running in software-only mode, so everything is going to use more CPU.

Are you sure you've enabled opera://flags/#ignore-gpu-blocklist and set opera://flags/#use-angle to D3D9 for example?

I'd also go right to the AMD website to get the latest GPU driver to see if that helps (with default settings or the above settings). Or, you can try the latest GPU from your PC's manufacturer's website. Sometimes that will work.

In that case, I suspect that you have the problem on Windows or the wrong BIOS configuration,
Set your BIOS by default and then do a full system update (Windows Update) or consider a reinstallation of the Operating System, because I don't think that the browser is your problem. Browsers reflect the system’s default acceleration, and this is enabled by default on Windows.

Play VP9 videos in any video app on your Windows 10 device. VP9 is a popular video codec for streaming over the internet. These VP9 Video Extensions are designed to take advantage of hardware capabilities on newer devices. For devices that don’t have hardware support for VP9 videos, software support is provided, but the playback experience might vary based on the video resolution and device performance. These extensions also let you encode VP8 and VP9 content on devices that don’t have a hardware-based video encoder.

Applies to web browser content also

I don't understand since this is an app not something I can run or attach to opera as an extension and call it a day. This is a video player that isn't youtube and doesn't have youtube... I guess I just don't see what this suggestion was suggesting when the issue is about youtube.

In previous versions it was the opposite situation.
*The best performance for me is now in Dev version with 'h264ify' extension disabled and with 'static indicator' flag enabled.

I don't use battery saver because it also limits PC's resources

True. Frames are skipping badly on youtube with battery saver, unfortunately. Not perfect solution, but i still use it on fanless PC, so that it does not overheat.

Also, as @andrew84 wrote, the option to turn off the animation should be available regardless of whether a user is using the battery saving feature or not. I can't tell you if Opera's devs are already working on it, or if it is even planned, because I am one of the users and not an Opera employee.
I think you will get a better answer, if you ask about it on the blog.
