Jerk when playing video

Help and Support Raspberry Pi
1

Hello.
First of all sorry for my English…

I have playback problems on video : there are some jerk (image stop and restart very quickly).

Hardware : Raspberry Pi 2
Version : OSMC 2018.12-1 - Version : OSMC running Kodi 17.6 -> no problem
update to : OSMC 2019.04-1 - Version : OSMC running Kodi 18.2-RC1 -> jerk problem
fresh install of : OSMC_TGT_rbp2_20190623.img -> same problem

As you can see the only thing changing is the OSMC version. Just in case, Raspberry Pi is connected to TV on HDMI port, network, and a powered USB hub for a 2.5" HDD. No additional card.

I don’t check with all my video files, but with 2 files coming from the same source : French TV broadcast recorded with a VBox XTi-3442.
Perhaps there is a specific codec for these streams.

To repeat the problem I just have to play the video, problem appears from the begining. Tell me if you need the video file to reproduce the problem.

You can find here the stream information get with mediainfo :

Thanks for your work (I use Kodi on OSMC every on Rasperry Pi since 5 years) and to help me to resolve this problem.

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

  • reproduce the issue

  • upload the log set 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.

I tried this but I have the URL https://paste.osmc.tv/<html> when I enabled “all configs and logs”.
I flashed a new SD card and this time it’s OK :

Try Settings -> Player -> Videos -> Adjust display refresh rate -> On start/stop

Thanks for your answer.
I tried with the “On start/stop” option but I still have the jerk problem (perhaps a little bit different, but not less).
You can find logs at : https://paste.osmc.tv/cuzasokayo
I tried also with “Always” option but there is no difference.

Il faut activer l’option “Ajuster le taux de rafraichissement d’affichage”. Testé sur 2019-11-1.
Cette option n’était pas activée sur la version 2019.04-1 et pourtant je n’avais pas ce problème d’image saccadée.
Pour information le Raspberry Pi 2B est connecté sur un téléviseur Samsung UE32F6400.

English please!

Google Translate:

“You must activate the option “Adjust the display refresh rate”. Tested on 2019-11-1.
This option was not activated on the version 2019.04-1 and yet I did not have this problem of jerky image.
For information, the Raspberry Pi 2B is connected to a Samsung UE32F6400 television.”

Do you have motion plus enabled on your TV?

Thanks Tom.
