Then it looks like a libglib2.0-0 error, which is totem dependency. Maybe related to your hardware/mem.
Checking the totem settings, via dconf (dconf-editor), all the options here are 'off' except the first one 'autoload-chapters' (org.gnome.totem) Note: #4 expose glib error, but #6 says no error !!! Note2: is there some 'journalctl -b' related error when you double click on a mp4 video to be played via totem ? ** Package changed: gstreamer1.0 (Ubuntu) => glib2.0 (Ubuntu) ** Changed in: glib2.0 (Ubuntu) Status: Confirmed => Incomplete ** Also affects: totem (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gstreamer1.0 in Ubuntu. https://bugs.launchpad.net/bugs/1760274 Title: videos are stuttering extremely Status in glib2.0 package in Ubuntu: Incomplete Status in totem package in Ubuntu: New Bug description: I am using totem, stuttering are not in browser.
