@maphew i believe that is a different library entirely so I'm a bit unclear if it fixes the root issue or replaces pytube with a different library when loading

We likely need to update our requirements.txt -- would definitely appreciate assistance here!

@RONNCC Thanks for the prompt attention. I didn't realize pytube & pytube3 are in a state of flux, once forked and now trying to come back together. The PR was just a naive implementation of the comments in #672. I'll see if I can find a way to help. There's also the fork-of-fork https://github.com/H4KKR/pytubeX.

A suggestion: create an issue out of the "actively calling for maintainers" part of the Readme. Pin it. Then reach out to folks like @H4KKR who have been active fixing bugs and making PRs in recent months.

(and: I'll close this PR after you've read it. It doesn't serve the right purpose)

I'm not really sure how they go together/work - need to dive into that more 😄

Good idea! Done in #698
