VLC Won't Play Video Files From NAS SMB Share With Dolphin

Hi,

I’ve been having trouble with one particular install where VLC refuses to play any video files if I try and play them from Dolphin. Haruna will play them from the same Dolphin instance though.

VLC was the native installed version. I’ve also uninstalled and installed the flatpak version and it too has the same issue.

The network share was created within Dolphin by adding to “Places” after navigating to the folder. Here’s the location
smb://qnap-ts453d.local/Shared Multimedia

With the native VLC version:

  • media playback fails trying to start from Dolphin by double clicking the file. I receive the following error message
VLC is unable to open the MRL 'smb://qnap-ts453d.local/Shared Multimedia/Movies/(Genre) Aliens/Abyss, The (1989) %5BAdventure.Mystery.Aliens%5D/The Abyss (1989) Uncut SE.mkv'. Check the log for details.
  • I get the same error message when trying to open the file with VLC already open and browsing to the same location.

The output of the log file (I went into VLC Settings/Preferences/Logger and created a log file) is

main: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
main: playlist is empty

With the Flatpak version, I get the same errors trying to play the file from Dolphin. However, if I open VLC first and navigate to the file from VLC, it will play.

In both instances, navigating to the “kio-fuse” location will play the file

run/usr/<guid>/kio-fuse-aNMxrz/smb/qnap-ts453d.local/Shared Multimedia/Movies/(Genre) Aliens/ Abyss, The (1989) \[Adventure.Mystery.Aliens\]/The Abyss (1989) Uncut SE.mkv

If I use SMB4K to mount the shares, the files play as well. It only seems to be an issue if you create the shares using “Places”.

I think it’s a bug as I don’t seem to have this issue on another older laptop install (hasn’t been updated in a while). This laptop is now running Ultramarine 44, but still had the issue in 43.

Any help would be appreciated.

It sounds like the issue described here:

The KDE dev at the end suggests using kio-fuse, which does indeed work for you.

But (both in that thread and in your experience) the behaviour doesn’t seem to be consistent across different distros / versions. So I’m not convinced this is fully understood.

Yes, it seems like a similar issue. I checked the file permissions through Dolphin - this particular file under Properties:

  • “Permissions” has nothing
  • “Advanced Permissions” has all of the checkboxes marked
  • “Remote Permissions”
    • Owner: Unix User\501
    • Group: QNAP-TS453D\everyone

And this would probably be the same for most of the files on the NAS

I know there where issues with Dolphin and access to NAS shares towards the end of Fedora 42 where it regressed in KDE-Frameworks version. Although it affected all apps trying to access it through Dolphin. Even Dolphin had access issues where it wouldn’t allow you to copy anything. They ended up fixing it in 5.19? 6.19? Not sure but it was a 19 LOL.

Should I maybe post the issue over at KDE also?

I’ll also have a look at a couple of other installs I have and see if the issue is there too (although I don’t think it is.
