How to get the final url?
Because if i use "url" it does not work (403).
if I use url + &sig= s still 403

@Zibri this code is ~ 7 years old and I didn't tested it since then. You can expect that the YouTube "API" changed.

You should take a look into the youtube-dl command line project. See https://github.com/ytdl-org/youtube-dl

I know youtube-dl very well thanks...It was just a comment.Maybe a line of code can solve that.
