NFS from synology
Good morning

I do currently have some trouble with nfs exports from synology

I do have 2 NAS

- Qnap with fedora 27 on it
Code:
[jyl@QNAP ~]$ cat /etc/exports
/mnt/USB4/Documentaires *(ro,all_squash,insecure)
/mnt/USB4/Series *(ro,all_squash,insecure)
/mnt/USB4/Musique *(ro,all_squash,insecure)
/home/jyl/Videos/Films *(ro,all_squash,insecure)
It works perfectly as a source

and Synology DS 110J
Code:
Enfants> cat /etc/exports
/volume1/video    *(ro,async,no_wdelay,crossmnt,insecure,all_squash,insecure_locks,sec=sys,an​onuid=1024,anongid=100)

I can add the source, access it, but after a couple of seconds kodi crashes and restarts.
I do also have kodi on my laptop (fedora 27 XFCE), and it works.

I tried to spot errors in the logs, but nothing relevant, either in kodi or syslog. Any idea on what's going on?

thanks. :-)

I do not own any NAS, so I'm unsure if I can help, but I have some questions

1) Debug messages in Kodi enabled?

2) How are shares mounted on NAS (inside Kodi, from /etc/fstab, autofs) ?

3) Any useful infos in dmesg output?

RE: NFS from synology
Try enabling "Allow connections from non-privileged ports":

There are only 10 types of people in the world: those who understand binary, and those who don't

The rule is correct.

On Xbian I've enabled logging and debugging, and before it crashes:

The error occurs when I try to navigate in a folder
On my laptop I tried the following:
- access the NAS directly from the nfs share, seems ok, I have the icon preview and type of file, duration, etc...
- Access the NAS through the xbian upnp server, no icon preview, nor information.

My guess is that kodi trying to generate the preview icon for every file and it can't. Is there any way to disable that? I don't care about preview, I'd just like to have a list of files.

The error occurs when I try to navigate in a folder
On my laptop I tried the following:
- access the NAS directly from the nfs share, seems ok, I have the icon preview and type of file, duration, etc...
- Access the NAS through the xbian upnp server, no icon preview, nor information.

My guess is that kodi trying to generate the preview icon for every file and it can't. Is there any way to disable that? I don't care about preview, I'd just like to have a list of files.

Have you already tried this? FYI, this has move to Settings / Media -> Video

Are you using OMXplayer or VideoPlayer (MMAL) acceleration?

Can you disable "Use GPU for jpeg acceleration" if it is enabled

And, on the other NAS, are there same type of videos (rmvb)?

RE: NFS from synology
That's it!

1) I've disabled the option "extract icons and video information" from parameters/media/video (advanced mode)
The bug is gone.

2) I've then moved the rmvb files into a dedicated folder, and reenabled the "icons and video information" option
Everything is fine until I try to access the folder with the rmvb files inside.

3) I've copied the rmvb folder to the other nas, same faulty behavior.

4) After investigating deeper, it appears that a single file makes kodi hang (le voyage de chihiro). the other RMVB, they just can't be read.

5) everything is working fine, and has always been on the kodi installed on my laptop's fedora.

conclusion
This file format (rmvb) is now deprecated.
Since there is no point tilting against windmills I'm going to remove these files from the nas and reencode them with handbrake.

If anybody is interested by deeper investigation, I can provide a download link to the rmvb files.

Thank you very much. Smile

Yes, please. Will see what Kodi Leia is doing with that file

@Chiron
Kodi Leia Alpha 2 does not have any problems showing thumbnails of this file
(OMX disabled, MMAL enabled)
... and VideoPlayer with MMAL enabled perfectly plays this video
... and Kodi Krypton (17.6) crashing immediately when accessing folder containing this video.
