Hi guys,

I've got a problem. I've made new installations on two media center. Both running Debian (minimal install with xfce).
I have jitter on both systems (difference is only Intel i3 / i5). Before this new installation I used Ubuntu 16.04 and had no jitter.

Debug Log:

The jitter is constantly and looks like this (numbers are frame numbers)

...1 2 3 4 4 5 6 8 9 1 2 3 4 4 5 6 8 9...

It seems like 1 frame (nr. 4) is paused/doubled, and "later" (half a second maybe) 1 frame (nr. 7) is jumped over. I can see this very intense on smooth camera panning.

Kernel:
"uname -a" => Linux debian-pvr-tv 4.11.0-2-amd64 #1 SMP Debian 4.11.11-1 (2017-07-17) x86_64 GNU/Linux

my "apt/sources.list" has the additional entry (for Kodi 17.3 instead of 17.1):

deb ftp://ftp.deb-multimedia.org stretch main contrib non-free

It doesn't matter if it is a movie with 23,976fps or live-tv with 50fps.

Debug-Log is deleted...

I hope someone knows what causes the problem.

Greetings, Pyro

Maybe this is a hint?

You run an unsupported build. Krypton was never intended to be used with FFmpeg != 3.1

Ok, thanks for the hint.

I will look how I can downgrade ffmpeg on debian...hopefully this is the cause for the jitter.

I've installed Xubuntu 17.04, with the official PPA
deb http://ppa.launchpad.net/team-xbmc/ppa/ubuntu zesty main
deb-src http://ppa.launchpad.net/team-xbmc/ppa/ubuntu zesty main

Still the same like above. And...I don't think its the TV, because the Samsung TV and the Benq Projector are showing the same behaviour.

...any other ideas?

[wsnipex]

new log would be a good idea. Also, did you try nightlies yet?

New Debug Log: https://pastebin.com/zh6MPwTa

Nope, didn't tried nightlies; next item on my todo list.

Same on Nightly Build

Just for your info:
Fresh install with Ubuntu (LXDE) 16.04 LTS, the official KODI 17.3, everything runs smooth now, no jitter.
Maybe the problem is the kernel, or intel-driver?

I like Linux, but ain't a pro, so I can't investigate further, sorry.
