Stuttering (some) videos, from NAS and even USB


#1

Hi everyone,

I have a RPi 3 plugged into my TV through HDMI, OSMC installed and a NAS with my media files.
This is my first installation.

When i play some video files i get stutters every about 2-3 minutes : the sound is ok but the image slows down and then accelerates ! It depends which file i play.

I tried OMX, MMAL, from the NAS, from a USB key… I don’t know what to do ! Of course the file plays well on my computer with VLC player.

My logs https://paste.osmc.tv/arirunosat

Do you need media info of this file (and maybe of a file which plays well…) ?

Thanks a lot !!

Best too if you can provide media info & a clip of the video with the stutter. Also, if you can keep it at 200-300MB that would be swell :smile:

Your log shows that you’re running a kernel that doesn’t seem to have come from OSMC.

Nov 03 18:16:42 OSMC_Orey kernel: Linux version 4.14.83v7-aufs (max@lynx) (gcc version 8.2.0 (Buildroot 2018.08-gbbba56f1-dirty)) #1 SMP Wed Nov 28 22:52:43 CET 2018

Could you explain what it is, and why you think it’s not the cause of your problem?

I really don’t know, i installed OSMC through Berryboot.

OSMC image available on this page https://berryboot.alexgoldcheidt.com/search-downloads/?dl_cat=0&dl_search=osmc

I’m a newbie :confused:

Well that would explain it. Try to reinstall from the Official OSMC download page


#11

Berryboot is not supported.
It changes kernel and firmware so we cannot offer any support.

Use NOOBS if you need multiple OS support.

Hi dillthedog,

OSMC re-installed, using NOOBS.

Same issue… My new logs :

Thank you again :slight_smile:

I suspect your encode is bad. Have you tried other files or is the problem only with the GoT files?


#19

Hi bmillham,

I’m playing other files right now (The Walkind Dead, some movies…), so far so good !
The problem seems to only happen with some GoT files (some in SD quality, none in 720p quality).

i’ll keep testing tomorrow with other files…
Thanks !!


#20

If you could get a sample of one of the problem files (1 minute or so) that could help find out the problem.


#21

Here the file https://www.dropbox.com/s/u5aeggdx6jntlyg/GoTout.avi?dl=0

Same issue with it…


#22

The file plays fine on my Pi3B+ with Leia v18 if and only if I deactivate OMX and MMAL hw acceleration support at settings -> player -> video. I think this is a typical sign that something is wrong with the coding.

Thank you JimKnopf, it works !!!
I thought it was necessary to activate at least one hw acceleration :thinking:
