This project is awesome for "watch it later" or just when you're on flaky wifi and don't want to get stuck buffering every three seconds. Use 'pip install youtube-dl' if you're already set up for Python development — and you can use it in your own code just as easily, although features like batch downloading are already accessible through the CLI.

youtube-dl works great, constant updates make this best YouTube extractor out there and I've tried number of them. Currently use it as a core component on my site.

I've been using youtube-dl for some time, and it's great.
