Bug#990083: kodi: Kodi hangs on transitions between playlist items with spinning wheel and no control

[Fabrice Quenneville]

Package: kodi
Version: 2:19.1+dfsg2-1
Severity: important
X-Debbugs-Cc: fabquen...@gmail.com

Dear Maintainer,


* What led up to the situation?

Updated to version 2:19.1+dfsg2-1 and now kodi hangs with a spinning wheel after every playlist video, also starting any video is now slower to start since update

* What exactly did you do (or not do) that was effective (or ineffective)?
pkill kodi does nothing
pkill -9 kodi works
controls within kodi dont work while wheen is spinning indefinetely
After waiting a while it goes to main menu, freezes and sometimes after a while kill gnome and return me to gnome login

* What was the outcome of this action?
If I kill kodi manualy I can just reopen it and play any video

* What outcome did you expect instead?
The next video playing

Other info:
My kodi starts on boot
My videos are all on system mounted NFS share and the network / shares work while kodi goes awire
I have the Extras, Youtube, WatchedList and BingBackground add-ons installed

Hi Vasyl / maintainers

I just got other errors from that NAS so I am starting to run diagnostics but it will take awhile to troubleshoot and it is quite late here. But everything is pointing to my NAS partially failing at the same time as I updated Kodi. I will update as soon as I can / have definitive information.

Thanks

Hi Fabrice!

Does the file '/mnt/media/TV Shows (en)/Seinfeld (1989)/Season 3/Seinfeld.S03E19.The.Limo.720p.WEBrip.AAC.EN-SUB.x264-[MULVAcoded].mkv' play for you correctly every time you start it not via playlist?

From the logs I see that VAAPI on Intel integrated video (I suppose it is an integrated video) starts spewing 'COutput:StateMachine' errors.

I am going to forward the bug to upstream and ask FernetMenta or ksooo about that StateMachine state. In my experience, these errors originate either from buffer jitter or from improperly-encoded mediafile.

Hello

So I've got my NAS back on and tested, everything is fine there and Kodi crashed again on a transition. I think rebooting the NAS when I suspected it was the source of the Kodi issues is what caused my NAS issues... But just a remount of the subvolumes after an errorless check and some btrfs diagnostics and no errors found... The only thing I could see is a few machines on my network saturating the NAS and simultaneous backups but it's never been an issue before with much more load than now.

So I've had two events since:

• The first one I was not ready so I only captured a regular log: 2021-06-20-04∶22∶27 PM-kodi.log
• Just now, where It froze on a transition and exited userspace bringing the OS back to a gnome login screen. 2021-06-20-19∶30 PM-kodi2.log This time I was waiting for it and had a file explorer ready on the problematic PC and another PC on the same part of my network. While the problematic PC was temporarily frozen so I could not test opening a video on another app, I was able to open one on the other PC with no problem. (I opened a random video as I didn't remember what was next on kodi.)
• As soon as I could get the log (sftp was also not responding on the kodi machine) I also tested the problematic video file and there's nothing wrong with the video file that had just crashed userspace.
• And when I logged in there was no sound but that video file was working fine. (sorry for the two logs I opened two kodi instances for a few seconds by error.). 2021-06-20-19∶50 PM-kodi.log and 2021-06-20-19∶52 PM-kodi.log

After a reboot everything is back to normal. 

Thanks

Hi,

I have shut down my NAS as something strange is happening on it. But since my NAS is off I have been watching YouTube through the KODI add-on and I also get some similar crashes.

I will try to generate meaningful logs in the next few days when I get some time.

Thank you

Hi Fabrice!

Just curious: can you please use Kodi's built-in functionality to access NFS agare, not system mount and see if it helps?
Maybe create a backup of Kodi profile & try mounting in userspace.

Hello,

I have done extensive testing and stress tested my setup and was not able to reproduce the bug again.

I suggest you close this bug, sorry to have wasted your time.

I suspect something wrong happened on my NAS and the client NFS didn't like it and crashed on transitions. And in the steps i took one must have corrected the issue as I can no longer reproduce the problem.

I do get crashes sometimes opening menus but that is a whole different issue that I believe is already tracked from looking at the project on GitHub.

Thanks
