VideoPlayer crashes a few seconds after starting to play a video at times

Help and Support Raspberry Pi

Hello OSMC team,

I have an issue with the VideoPlayer which seems to sporadically crash every once in a while and I hope you can help to try figure out wjy this is happening.

This happens sometimes when I start a video, When this happens “ps aux” runs but it hang at what it’s probably the process that is hanging.

Tried restarting kodi, althought technically it’s the VideoPlayer that is causing the issue so the stuck images remains on the screen until the power to the Rpi is removed and re-applyied.

Full log included here:
removed

I only recently replaced the minisd card so I think it’s unlikely to be an issue with reading on the card.

Solution:
Soft reboot doesn’t work , plsae remove and re-apply the power.

Thanks for your help.

How do you power the device?

Your crash is an out-of-memory killer.
You didn’t have debug enabled when capturing the log, so diagnosis is limited.
I did spot:

                                              <network>
                                                <buffermode>1</buffermode>
                                                <cachemembuffersize>20</cachemembuffersize>
                                                <readbufferfactor>157286400</readbufferfactor>
                                              </network>

Looks like your cachemembuffersize and readbufferfactor are swapped…
And the names of the tags have changed on kodi 17.
http://kodi.wiki/view/HOW-TO%3AModify_the_video_cache

You also have many banned repos/add-ons installed, so you are unlikely to get help here.
Please remove and confirm if problem still occurs.

Thanks for pointing out the wrong sub network tags, I’ve swapped the values around, and removed most unsupported addon i think.

5

Do you have a new log after the changes?

6

That there’s a kernel panic, aka “oops”.

7

the issue didn’t occur that often to begin with but sometimes was quite regular.

Maybe was the erroneous/swapped readbufferfactor and cachemembuffersize which could have caused the out of memory issue.

I haven’t seen the issue since, so it’s looking good so far, I’ll update you and provide more logs if the issue persists, which should be obvious in the next few days.
