ytpod is a YouTube channel RSS generator compatible with Apple Podcasts or other players like AntennaPod.
There’s a public instance hosted on fly.io that can serve as an example. Basically, to obtain a feed of a YouTube source, one can just forward the YouTube path, for example, a feed from the author’s channel can be obtained via:
https://ytpod.fly.dev/youtube/feed/@lordawesomeguy
https://ytpod.fly.dev/youtube/feed/user/lordawesomeguy
https://ytpod.fly.dev/youtube/feed/channel/UCGFSAnRMBuCeEIiAAlKzdfg
This service fetches RSS feed from YouTube and enriches it with direct audio streams. Keep in mind that the code quality is rather poor because it is nothing more than a hacky weekend project.
