The first thing to check is whether your current video mode (run 'xrandr') matches the video file's frame rate to at least two decimal places. If it doesn't then there will be frame skips several times per minute.
Separately, since you're using unsupported 'kisak' graphics packages that are not from the Ubuntu archive, we can't support the system or accept bug reports from it in that state. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2093176 Title: Video Stutter all players tried Status in Ubuntu: Invalid Bug description: When playing a video file with frame rate that matches the refresh rate of the monitor there is a stutter every couple of seconds (5-10) 50hz playing 50fps video 60hz playing 60fps video 24hz playing 24fps video (this one was tested on a nother system running arc a310) The lower the refresh rate is, the more obvious the stutter is. Easiest way to see it is to play a tearing test video that has vertical bars running across the screen. Seems that at regular intervals a previous frame is shown, its like the internal frequency calculation is off and corrects itself every couple of seconds. This happens with all players that I tried - Kodi, mpv, smplayer, also happens in chrome and firefox when playing a youtube video. Tested it on 2 systems - this one is integrated intel graphics, second system is newer - with a intel arc A310 video card - both systems does exactly the same thing.
