VLC and MPV cannot play video files from samba share

With a FreeboxPop server (see NOTE at the end: this is not limited to the Freebox server, but all samba shares are affected). It has an USB entry where I have put an external 2 GB drive containing mostly videos that I can thus access and play very well with an Android TV device (or with the phone etc).

But, to my surprise, on a rather old laptop running Kubuntu 22.04, while Dolphin can access that drive and make changes to it, video files cannot be played by the video players I normally use - VLC and MPV.

Photos are instantly opened by Gwenview.

PDFs are opened in Okular but the file is first copied on the computer it seems.

MPV gives this error:

mpv 'smb://freebox-server.local/Volume 2000Go/FILME/IT_2/---a-voir/A.Mezzanotte.Va.La.Ronda.Del.Piacere.1975.mkv'[ffmpeg] Protocol not found.

(Errors when loading file)

That might be ffmpeg-specific, but VLC is also unable to play:

Trying with Gwenview:

kf.kio.widgets: Failed to check which JobView API is supported "The name org.kde.kuiserver was not provided by any .service files"

Kodi allows the Freebox share location to be added, and then starts playing video (although sometimes it freezes).

I was also pleasantly surprised to see how old Xine plays very easily those videos (instantly!).

But other players also work, like Totem (Gnome's 'Videos') and Glide, installed as flatpak.

Testing in a live session of Ubuntu 22.04 (Gnome) the same problems are present with MPV and VLC - while the file manager (Nautilus) can access those files and the Gnome video player ('Videos', that's Totem I guess) can play the videos (after installing the needed codecs).

Are these problems related or should I treat them separately (MPV from VLC)?

NOTES AND UPDATES:

• kio-fuse is installed
• this is not limited (after more testing) to the Freeebox samba share, but to other samba shares too:for testing purposes I have created a samba share on my Android phone, and videos on the phone have the same problem with MPV and VLC on Kubuntu 22.04
• sharing the 'Movies' Android phone folder on FTP with Solid File Explorer, they can be played by VLC and MPV on this Kubuntu 22.04
• Beside Kodi, also SMPLayer, although using mpv as backend, can play fine the samba shared videos!
• Other mpv-based players, like Haruna and QMPlay2, don't work
