Corrupt Video after 30 seconds

[Jimhaddon]

Hi.

My Raspberry Pi 3 has started having issues with playing videos. Specifically it looks like the video is corrupt after playing for around 30 seconds. The video itself is not corrupt as it plays fine on other devices. The pi is connected via ethernet cable and videos that previously played fine now do not.

Here’s my debug log…

Does anyone have ideas as to what could be causing this? To me it looks like a hardware issue with the pi.

Share the mediainfo of the file.
Also ensure your network is still fine with iperf3 or try to play the file from USB.

I tried playing the video from USB and it works fine.

Then check your network with iperf3

[How To] Check Network Performance with iperf3

Sometimes it is important to check the network performance between your OSMC Device and the device providing your media (NAS, Server, PC). Especially when you are connected via wireless the throughput variations can harm you viewing experience. This short How To should give you the required information how to install iperf3 and how to run the respective tests. When doing these tests it is suggested to have a simple setup (single switch between Sender and Receiver and avoid other traffic on the …

Looks ok, may still be a corrupt file that only occurs via network.

Check Mediainfo via https://videosam.pl/ and share here

I noticed that if I increase the buffer sIze, the corruption happens later. E.g. 40 seconds instead of 30.

Also 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.

What are you sharing your files from? There is another thread where a few people are having issues with Kodi based NFS paths. You might try a system mount and see if that gets rid of the issue. If that doesn’t do the trick I would test it with a stock config.txt and without the cache mod in your advancedsettings.xml.

And full mediainfo as requested by fzinken please?

[Jimhaddon]

Thank you. Justtto confirm that setting up the nfs share via fstab works fine. Not sure why the old method stopped working.

[darwindesign]

Glad to hear. You can do a path substitution to automatically redirect your current library to use this system mount. Instructions can be found in this thread…

[HowTo] Repairing File Paths with Path Substitution

This guide is intended only as a more in depth instruction for manipulating file paths either for broken links or performance modification. For other applications of path substitution you can consult Kodi’s wiki on the subject. At its core, path substitution is a simple concept. You are simply adding <from> and <to> tags to an advancedsettings.xml file that specify a part of a file path that will get replaced, and the new path that will be replacing it. Kodi will use this whenever it is trying …

What is hosting your files if you don’t mind?

It’s OMV on 3 raspberry pi 3 with a hdd connected via USB.
