Firefox and Chrome/Chromium use software video decoding by default. They might also have "hardware acceleration" options for you to try, but to the best of my knowledge they don't do properly efficient hardware decoding. So this is a bug (two bugs) in the web browsers.
For a proper future solution see: https://chromium-review.googlesource.com/c/chromium/src/+/532294 For a simple workaround that works today, see: https://wiki.ubuntu.com/IntelQuickSyncVideo#YouTube Another issue you will find is that Gnome Shell (especially Wayland sessions) stutters and drops frames more than it should. And this problem will be visible in your videos too. I have a list of causes for that: https://trello.com/c/Q6JYXPPs Many people report better performance using Xorg sessions, for now. ** Summary changed: - Video processing on GPU with Wayland drops too many frames + Video playback in Google Chrome or Mozilla Firefox with Wayland drops too many frames -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1796013 Title: Video playback in Google Chrome or Mozilla Firefox with Wayland drops too many frames To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1796013/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
