Looking at your post and what I entered at the command line, it turns out I got the commands mixed up! My mistake was missing out a “-”. It should have been: grab-log -A or grab-log --all not what I entered grab-log -all!
I’ll try and recreate the error and reupload my logs.
It happened again and I got the command correct this time!
I had to restart OSMC as running the grab-logs command on the crash did nothing. The reboot was around 0748. This time it crashing while seeking through a YouTube video, yesterday it was a file on a NFS mount.
As you logfile is full of platinum errors I would suggest you temporary disable that if you really want to do troubleshooting on your seeking crash as it is impossible to see the failures with all that platinum messages.
Well you have installed some banned repository which most likely installed it for you. Suggest a clean start without the repository and see if that solves your issues.
I have the same problem when streaming and sometimes playing local video files. I never had a problem up until April’s update. Here’s my log file: http://paste.osmc.io/nosovubehu
Tried disabling OMXplayer but made no difference
Is “ERROR: CDVDMsgGeneralSynchronize - timeout” causing the crash??
