Maybe join forces with ytdl?

[akavel]

See: https://github.com/otium/ytdl - I've seen it show up some time ago. If not join forces, it would be helpful to at least provide info what are differences between your project and the other one.

@akavel this cli is liked the example for the core library https://github.com/dwarvesf/glod. If you are building your music streaming website, the command line tool to download media files or even a crawler ... you do not have to build it from scratch, glod is here to help.

And it may be the main difference that I can point out at the moment.
