Would require full debug logs (see below) and also mediainfo of the file you try to play.
To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.
Depending on the used skin you have to set the settings-level to standard or higher, in summary:
enable debug logging at settings->system->logging
reboot the OSMC device twice(!)
reproduce the issue
upload the log set (all configs and logs!) either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here
Thanks for your understanding. We hope that we can help you get up and running again shortly.
Additionally you don’t have adjust display frame rate enabled in your player settings so your also asking it to do additionally work there. If you wanted to play that particular file as is then you really would be best served with a Vero or RPi 4. If you want to stick with the hardware you have you will want to stick with h.264/AVC files.
Thats why… No problem, I am now aware to have everything in h.264 or convert it and call it a day.
To upgrade unfortunately I am waiting for months for RPi 4 for my 3D printer, so another one looks like next year and Vero is out of my budget. So I am stuck with this, it is slow, sometimes buffering, but it works (if it is not h.265).
