Normally that probably works over GVFS but mpv doesn't use that. It is probably worth opening an issue on https://github.com/flatpak/xdg-desktop-portal saying that selecting a file on an sftp mount does not work.

Workaround until the portal access is solved:

flatpak override --filesystem=xdg-run/gvfs io.github.GnomeMpv

--filesystem=host does not include any of the stuff in the xdg-run directory.

I just upgrade from Ubuntu 20.04 to 20.10 and get the same error:

Playback was terminated abnormally. Reason: loading failed.

I tried sudo flatpak override --filesystem=xdg-run/gvfs io.github.GnomeMpv but
can't play videos over LAN. Any fix ? I tried both Flatpak and apt repository

@aindriu80: Try running the command again with the current app ID: sudo flatpak override --filesystem=xdg-run/gvfs io.github.celluloid_player.Celluloid.

@aindriu80: Try running the command again with the current app ID: sudo flatpak override --filesystem=xdg-run/gvfs io.github.celluloid_player.Celluloid.

no luck. I've tried reinstalled it with:

sudo add-apt-repository ppa:xuzhen666/gnome-mpv
sudo apt update
sudo apt install celluloid

I noticed that I can play videos on the network by going into Celluloid, clicking on the + on the top right hand side and selecting a file to play. I was trying to play a video through Dolphin file explorer when I got the error

Playback was terminated abmormally. Reason loading failed.

Yes i found this on ubuntu 21.10 today too. It is only the flatpak version. It worked with the PPA install yesterday. Be fort i installed the flatpak version
