Not sure if this should be filed under dolphin, or kio-fuse. Navigating to a remote folder with multimedia files, like sound/video doesn't allow me to play the previews in the preview pane in Dolphin.
How are you navigating to the folder? Via Dolphin? Can you verify whether the path shown in the URL navigator is a FUSE mount path or not? A screenshot would help me help you. :)

Thanks. This view isn't provided by kio-fuse at all; it's provided by the SMB kioslave. Can you go to Dolphin's config window > General > Previews and tell me what the value is in the spinbox for "Skip previews for remote files above". I suspect it says "No previews". :)
I've actually got that set to 10MB.
Okay so you're seeing a bug in the SMB ioslave then. Moving this over there. FWIW it works for me. I have mine set to 5 MB and I see previews on my Samba share for files under that size. What version of Dolphin are you using? And what distro are you using? For future reference, these are good pieces of information to add to the initial bug report. :)
For the record, we're talking about the same preview right? The pane on the right? The play button is what doesn't work for me. Dolphin 20.12.2 on Manjaro Operating System: Manjaro Linux KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernel Version: 5.10.14-1-MANJARO OS Type: 64-bit Processors: 12 × Intel® Core™ i7-9750H CPU @ 2.60GHz Memory: 15.5 GiB of RAM Graphics Processor: GeForce RTX 2060/PCIe/SSE2
Oh, the play button doesn't work? I thought you were talking about the fact that the icons don't have thumbnails. Reading through the text you wrote, I have no idea why I got that confused. I can confirm the real issue. Might be in Dolphin, or might be in the smb ioslave. Leaving it here for now.
Which phonon backend do you have installed?

Moving to pgst then, though I'm not sure that is even maintained. The KIO->phonon streaming interface isn't ideal but practically it should and does work for me with VLC. In fact, without knowing why pgst falls on the face I don't see how to improve the streaming interface in a fashion that would help the backend fix streaming and also it'd need someone to write the code in the backend. There could be an argument made that dolphin previews of non-local urls should be changed to run through kio-fuse thereby avoiding the bespoke streaming code entirely and likely fixing whatever is wrong with the backend for the purposes of this feature.
This backend for Phonon is no longer maintained or supported, and has not been for quite some time. Please use the VLC backend instead--which is the recommended and maintained replacement--and see if you can reproduce the issue there. If you can, please open a new bug report at https://bugs.kde.org/enter_bug.cgi?product=phonon-backend-vlc. Thanks a lot!
