Graphical Stuttering Debian Kodi

jmgibson1981 · 08-28-2018, 06:05 AM

I recently migrated my server / htpc to Debian Stable. I have all my services up and running, better than ever to be honest. One thing remains.

When I play a video playlist on Kodi, the first video file plays perfectly every single time no matter which video I pick first. After that each video that plays in order is jittery and stuttering about. The audio is flawless, just the video glitches all over the place. This tells me it isn't a codec issue.

I have tried both AmdGpu & Radeon, neither with success. I've tried backporting the kernel, and the firmware with no success. As I got the same result with both drivers I'm thinking it could be something else, but have no clue what to look for. All I know is that this is annoying. It isn't a common problem I've found as video playlists don't seem to be something many people use. Google has been little help. I've tried every suggestion I've found about disabling hardware decoding, sync settings, and so forth.

I haven't a clue where to go next.

*EDIT* Forgot hardware info. Running commands > ssh

That inxi indicates that you may be going to have problems with your video card - or are you using basic integrated video?

I've loaded the manufacturers driver for my rather basic, but separate video card.
inxi -Gx gives

Why? Kabini is 5 years old. Inxi -Gxx really should be run from an X session to be most informative.
