The YouTube-webpage also has an option to export your subscriptions to an OPML-file (which can then be imported into an RSS Reader): Log into your YouTube-account, then go to "Manage Subscriptions", and then at the bottom of that page, there's a button for it.
(This is how it worked a few months ago. I actually don't have a YouTube-account anymore, so I can't check if it still works like that.)
On Android, I personally use SpaRSS [0] with it, which does work quite well, but it being available on F-Droid was pretty much essential to me, so if you don't care about FLOSS, you might be able to find an RSS Reader which integrates even better with this setup...

I threw it together (over a few hours) simply because I like watching stuff on youtube at 1.5x speed and the android app does not allow you to do it (whereas if you use VLC to play the downloaded video, you can increaseplayback speed)
It's also available on the play store [2] with youtube downloads disabled by default

For that reason I call it NewPipe/VLC, or as I've recently taken to calling it, NewPipe plus VLC.
