It does not work anymore, I'm receiving the following error:

There appears to have been a YouTube API change, same issue with the original code: https://github.com/Tyrrrz/YoutubeExplode/issues/179

DominicMaas commented 5 years ago

Looks like the folks at youtube-dl did this: https://github.com/rg3/youtube-dl/commit/2511eee215c2a66020ae927c86face826f48ba8e

I think I may have fixed it, what video did it break on? (so I can test to see if it now works).

Or this video: https://www.youtube.com/watch?v=YQHsXMglC9A

DominicMaas commented 5 years ago

I've performed some tests with those videos (and a few others), everything seems to work. I'll publish a new version shortly for you to double check.

Edit: Published.

davidgalarza commented 5 years ago

Yes, I've verified it, this works perfectly.

DominicMaas commented 5 years ago

Awesome!

htetwaiyan commented 5 years ago

I change the regex in stream-info-parser line(16) to like that int.tryParse(RegExp(r'([a-zA-Z0-9_-]{11})').firstMatch(parseUrl()).group(1)); is workout

htetwaiyan commented 5 years ago

I want to know how to download with video and audio stream together
