I'm really not sure what changed to make 4K video so stuttery now in totem. The CPU is fairly low and goes through the roof only if I uninstall VAAPI. So VAAPI is working, and it works smoothly in mpv too.
Since I could last play 4K smoothly in totem there has been: * A mesa update 17.2 -> 18.0 * A Xorg update 1.19.5 -> 1.19.6 * Kernel updates * Hardware changes (I changed from a Haswell to Kaby Lake desktop) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1698270 Title: Totem pauses and stutters during video playback even when CPU usage is low To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/1698270/+subscriptions -- desktop-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
