Downloading wrong playlist [bug]

[kevin-hanselman]

I am trying to downloading this playlist:

http://www.youtube.com/playlist?list=PLMCmkNmxw6Z9eduM7BZjSEh7HiU543Ig0

I have tried:

youtube-dl http://www.youtube.com/playlist?list=PLMCmkNmxw6Z9eduM7BZjSEh7HiU543Ig0

youtube-dl PLMCmkNmxw6Z9eduM7BZjSEh7HiU543Ig0

youtube-dl http://www.youtube.com/view_play_list?p=PLMCmkNmxw6Z9eduM7BZjSEh7HiU543Ig0

All of them start downloading a 100 video playlist that starts with Gangnam Style...

I have tried downloading a few other playlists and they work just fine, which leads me to believe there is a potential bug in the program. If not, am I just doing something wrong?

Hm, it is a bug related to the PL prefix that we strip.

Here we have to include it; sometimes we must not include it; sometimes including it changes the page layout. Great.

The playlist you referenced has been modified significantly. Do you have a new testcase for this problem? Should be solved anyways though.

@FiloSottile commited a fix to my issue. I cleared my playlist because I successfully downloaded those videos.

[FiloSottile]

The issue was not related to playlist content, but to the fact that the web
interface required the PL prefix, while the API eats it also without.

The official docs say that it is mandatory now, so (I think) that I edited
the regex to include it.

Note: that playlist is still a good test target, have a look at

and

That's a long random character string to get matched to YouTube Daily Top Tracks playlist. What are the chances? 😃
