FreeTube is a feature-rich and user-friendly YouTube client with a focus on privacy.
A massive thanks to @LuanRT for providing the fix regarding to the extraction of the deciphering functions. Also, big thanks to @PikachuEXE for coming up with a potential alternative solution!
Unfortunately the only invidious instance I've been able to rely on doesn't enable the API endpoints. The admin is a real trooper though. I'm not sure if it's the flagship.
I wish MPC had a linux version. One of the few pieces of Windows-only software (along with foobar2000) that I actually miss.
A few months back I decided to fuck around and see if I could get it working in wine, and it seemed to work OK, but pretty jank. Too jank to consider seriously using.
I used haruna and it works. The instructions on the FreeTube GitHub could be clearer though. Depending on if you're using FreeTube and or the external player as flatpak there are different ways to get it working.
I think I either tried that or didn't want to bother lol. I guess it felt slightly less janky to click on another backend on nadeko. Gonna update freetube for sure though. I probably shouldn't care to proxy videos that much.
