By the way: Here is what Fedora guys told me about integrating Ring packages into Gnome Software repositories.
> I'm interest in GNU Ring's communication solution.https://ring.cx/en > https://ring.cx/en/about/practical > "I see that FFMPEG is mentioned on Ring's website. FFMPEG isn't permissible in Fedora because the USA's patent system is crap, so it's packaged in RPM Fusion instead. Anyone who wants to package Ring will have to do it in RPM Fusion (or another add-on repository), unless Ring can function without FFMPEG. Björn Persson"
