I've launched a new project: PodcastMaker. TLDR: It is a program that converts YouTube channels into real podcast feeds complete with video enclosures.
Feel free to contribute, submit bugs, or just let me know how its working for you. PodcastMaker is released into the Public Domain and uses the Unlicense, just like
youtube-dl. Feel free to fork it, build things with it, whatever you want to do. This code is truly unencumbered. Go have fun. Or not.
