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.
