Brave is also not support Hardware-accelerated video decode.

[Bug 1872390] Re: 193% CPU usage while using webex with chromium
You are right. Hardware-accelerated video decode is currently not supported by chrome and also the chromium, released by Ubuntu. Brave or chromium-Beta is likely a way to get through it. Both of the browsers are not able to be installed from Ubuntu's repository. They are also not available in snap store.

For Michel-Ekimia The previous Graphics Feature Status is the information I got from http://gpu/ in chromium and in chrome, respectively. I did not check if the task was sent to GPU or not. But I am sure that when I use youtube with 4K resolution. I do find a process in htop showed chrome sent a task to GPU and I can find a corresponding number in nvidia-smi. Did that mean gpu video decoding is actually worked with chrome?

[Bug 1872390] Re: 193% CPU usage while using webex with chromium
For the update report, we had another webex meeting today. I try chromium initially, it showed situation similar to the one mentioned above. After that, I try chrome, it initially comes out very well. After an uncertain time point the CPU run up more than 100%. After I kill the process, the webex was closed. After that, I reload the browser without close it. Everything went smoothly for at least 2 hours. So far, the only thing I did different from the previous report is that I only turn on chrome but not both chrome and chromium. Not really sure if it is correlated to the situation. Also not really sure what the difference is between the initial open of webex meeting in chrome and reload one. Should I give bug reports for both high cpu usage (initially) and the low cpu usage (after reload) next time, if I encounter the same situation? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872390 Title: 193% CPU usage while using webex with chromium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1872390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1872390] Re: 193% CPU usage while using webex with chromium
Neither chromium nor chrome on linux are gpu video decoding capable. You have to use Brave for this ( with limitations) I guess Webex use Webrtc ( So may be VP8 ) Check the last section of chrome://gpu/ to know what decoding is supported. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872390 Title: 193% CPU usage while using webex with chromium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1872390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1872390] Re: 193% CPU usage while using webex with chromium
Thank you for your help. Yes, it is an bug report about Webex meeting. I enable hardware-accelerated video decoding on chromium (80.0.3987.163, official build, 64-bit) by editing chrome://flags. But, it still use around 200 % CPU. Noticeably, the process did not turn down when I close the tab of webex meeting. The functions enabled was listed below. "Graphics Feature Status Canvas: Hardware accelerated Flash: Hardware accelerated Flash Stage3D: Hardware accelerated Flash Stage3D Baseline profile: Hardware accelerated Compositing: Hardware accelerated Multiple Raster Threads: Enabled Out-of-process Rasterization: Hardware accelerated OpenGL: Enabled Hardware Protected Video Decode: Hardware accelerated Rasterization: Hardware accelerated Skia Renderer: Enabled Video Decode: Hardware accelerated Viz Display Compositor: Enabled Vulkan: Enabled WebGL: Hardware accelerated WebGL2: Hardware accelerated" I also try chrome (81.0.4044.122, official build, 64-bit) and enable hardware-accelerated video decoding. It use around 105 % CPU. The functions enabled was listed below.

[Bug 1872390] Re: 193% CPU usage while using webex with chromium
I assume you mean Webex Meetings? I'm not able to create a test meeting here to confirm the problem, but IĀ suppose this might have to do with chromium not enabling hardware-accelerated video decoding on linux. Can you by any chance test this with the Chrome deb package (https://www.google.com/chrome/) and confirm whether it is similarly affected? ** Changed in: chromium-browser (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872390 Title: 193% CPU usage while using webex with chromium To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1872390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
