If you continue to paste logs from both machines maybe someone can see a pattern ...

okay, I'll try to provide a crash_log with debug on.

one question: should I run the newest nightly or leave it with the yesterday's one ?

- update -

crashlog with yesterdays nightly: http://ix.io/2NEN

last line from dmesg:

[ 254.928231] VideoPlayer[933]: segfault at 50 ip 00007f808ac9d2fa sp 00007f7ff27f2580 error 4 in libva.so.2.1000.0[7f808ac98000+2a000]

Latest nightly is always preferred (in best case the issue is fixed).

You can enable debug logging without overlay in advancedsettings.xml.

crash_log with LibreELEC-Generic.x86_64-9.80-nightly-20210128-fb96fe2:

Ubuntu Pastebin

- pastecrash didn't work (no link returned) -

dmesg's last line:

[ 4501.067910] VideoPlayer[938]: segfault at 7efdec003870 ip 00007efdec003870 sp 00007efdd57f0578 error 15

TvHeadend service.log:

Ubuntu Pastebin

hint:

on the above NUC connected to the same DigiBit with TvHeadend 4.3 running the same TV channel I also see in the web-IF Continuity error's, but so far (TV is running ~30 minutes) only 1.

Unfortunately ix.io silently fail if the file is too long. Use

Code

 pastecrash -c >~/crashlog_$(date -Iseconds).log

and post the file manually.

Regarding the VAAPI decoder errors you can try the older intel driver by creating:

Code: /storage/.config/kodi.conf:

MESA_LOADER_DRIVER_OVERRIDE=i965
LIBVA_DRIVER_NAME=i965

nightly-20210129-f41aa8c with the above kodi.conf

kodi.old.log:

Ubuntu Pastebin

why a kodi.old.log only ?

well, the box didn't crash (no crash log generated).

the running TV channel/broadcasting was just frozen.

no black screen or crash.

box was pingable, but no ssh into it anymore.

hard reset needed to get it live again.

It's again the same ffmpeg error message:

Code

2021-01-30 22:48:57.397 T:938     ERROR <general>: ffmpeg[0x320be90X]: [h264] get_buffer() failed
2021-01-30 22:48:57.397 T:938     ERROR <general>: ffmpeg[0x320be90X]: [h264] thread_get_buffer() failed
2021-01-30 22:48:57.397 T:938     ERROR <general>: ffmpeg[0x320be90X]: [h264] decode_slice_header error
2021-01-30 22:48:57.397 T:938     ERROR <general>: ffmpeg[0x320be90X]: [h264] no frame!

I have no idea which component fails on the broken video stream. You can try to open a kodi issue on github.
