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 Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1698270 Title: Totem pauses and stutters during video playback even when CPU usage is low Status in GTK+: Fix Released Status in totem-pl-parser: Confirmed Status in clutter-1.0 package in Ubuntu: Won't Fix Status in clutter-gtk package in Ubuntu: Fix Released Status in gtk+3.0 package in Ubuntu: Fix Released Status in totem package in Ubuntu: Confirmed Status in totem-pl-parser package in Ubuntu: Fix Released Bug description: Totem pauses and stutters during video playback even when CPU usage is low. After figuring out how to play videos with full hardware accelerated decoding (e.g. <= 10% CPU), I was surprised to find Totem still pauses and stutters during playback. Other apps like Mplayer, VLC and even gst-play-1.0 never have this problem.
