Thank you very much.
Disabling DRMPRIME in the expert settings solved the problem for me.
I wasn't aware that the hardware decoders can have such an impact on system stability. If the decoder stops playing my (maybe broken/non-standard) ile -> ok. But, freezing the whole RPi4?
Below is a picture of this "100" with a ring.
Is this from RPi4 firmware? Is it from Kodi? Or from LibreELEC?
Any idea?
(The picture shows the start of a movie. I then skipped to 9min 28sec, but the "100" shows up and sound and picture freezes)
Dear LibreELEC experts.
A few weeks ago, my Raspberry Pi 4 (2GB, "Full Armor" case, original 3A power supply) started to freeze when playing (skipping through) h264 videos.
It always starts with a white "100" and a blue circle around in the middle of the TV. Then, after a few seconds the picture+sound completely freezes and my remote ssh session is stopped ("Timeout, server libreelec not responding.").
I could not find out (Wiki/search) what the "100" is telling me.
Please, help.
Michael
PS: a few things that I tried.
* The problem appears with LibreELEC versions 9.2.latest and 11.0.3
* I copied the .m4v file to the µSD card and the freeze also happens when playing from smb (1GBit/s LAN; Ubuntu 22.04LTS fileserver) and when playing from µSD card of the RPi4
* The .m4v file plays fine on a Windows 10 PC and a Linux notebook with VLC
* I wrote (dd) the LibreELEC 11.0.3 image on a different SanDisk Ultra µSD card. The same freeze happens.
* beeing logged in remotely via ssh I triggered by skipping through the .m4v (left-clicking with the mouse on the time bar) the "100" and the following freeze
