Quick shout-out to Grayjay: An app to watch videos on any platform - reducing the power of individual services. The Software is open-source and can be found here: https://gitlab.futo.org/videostreaming/grayjay
I will test this out for myself and hope someone here finds this useful.
I tried to import my subscription from YouTube to the app but I got rate limited due to the large amount of channels. Is there a way around it?
You’ll probably want to report that to the devs. It is in alpha so there is a lot to add, fix, and tweak.
