Make sure jnn-pa.googleapis.com isn’t blocked anywhere in your network. It may perhaps be blocked in a filter list you have activated in uBO, DNS, VPN, Firewall, anti-virus, Firefox enhanced tracking protection, etc.

Appending (intext:“modlog” & “instances” & “docs” & “code” & “join lemmy”) to your search query will search most instances. Works with Google, Startpage, SearXNG afaik.

I think I also had this issue using Cinnamon once, but then I just used VLC instead. Never bothered to look into why. Worked fine in GNOME for me though.

I found a thread with a similar issue: https://forums.opensuse.org/t/flatpak-mpv-broken-since-20240306-snapshot/172981

There it seems the issue was audio. Try running the flatpak version with flatpak run io.mpv.Mpv --ao=pulse path-to-your-media-file

• On June 3rd, Chrome(ium) users will start being informed that their MV2 extensions will soon stop to function. uBlock Origin (and others) will lose the “Featured” badge.
• The remaining MV2 extensions will be gradually disabled in the “coming months”, with the last deadline being the beginning of next year. (Expect that uBO will probably not last that long).

What options do you have if you still want to use uBlock Origin?

• Firefox (and up to date forks) have no plans to end support for the webrequest API that uBO requires.
• Brave browser will allow MV2 extensions for now. I still have no info on if they are going to use their own store or require manual installation/updating of MV2 extensions.
• If you use Chrome. By enabling enterprise policy ExtensionManifestV2Availability, you should be able to extend support till June 2025.
• uBlock Origin Lite (uBOL) is a MV3 extension that is much more limited than uBO and is not intended to be a replacement for uBO. These limitations are described in detail in the FAQ for uBOL: https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-asked-questions-(FAQ)

Mint is known to use old software in its repositories as it’s based on Ubuntu LTS. The flatpak mpv should work though. flatpak install flathub io.mpv.Mpv and then run it with flatpak run io.mpv.Mpv https://www.youtube.com/watch?v=dQw4w9WgXcQ

If you don’t want to type flatpak run io.mpv.Mpv all the time, you can create an alias in your ~/.bashrc file. For example: alias play='flatpak run io.mpv.Mpv'. (After editing your bashrc file, run: source ~/.bashrc to activate the change). Then you can run it with play https://www.youtube.com/watch?v=dQw4w9WgXcQ.

Your mpv or vlc versions may be too old. Try updating them to the latest versions.
