Hello,
I am using LibreElec 11.0.4 on a Raspberry Pi 4 (official power supply). While playing videos (typically 1080p on Youtube, HW or SW), I experience sudden video pause, a brief screen tearing and eventually a system crash followed by a full reboot of LE. These problems happen after some time (typically 10 minutes) but the CPU and GPU temperatures seem fine (under 60°). If I stop the video player, wait a few minutes and start a new video, the video does not play, not until I fully reboot LE. The problem seem to be related to the network but I am not sure.
I tried to generate a debug log so I switched on the logging mode. Interestingly, the video problems happened much later. But after it happened and video playback stopped, I could not produce a log file, neither through the GUI (in the settings menu, LibreELEC → System) nor through SSH with pastekodi.
I unplugged the ethernet from the RPi 4 and plugged it again and then I was able to generate a log file but it had restarted...
Desperate, I tried the LibreElec 12 nightly and it solved the problem! Also, the image quality is now fantastic.
