and I tried to change the "playlist?list=" to "view_play_list?list=" or "view_play_list?p=", it still didn't work

[friyal]

And if I turned the playlist to be public, it can find the playlist but tell me :
[youtube:playlist] playlist 'xxx': Collected 0 video ids (downloading 0 of them)

Thanks, we'll have a look at it. Do you see the same problem with

youtube-dl http://www.youtube.com/playlist?list=PL63F0C78739B09958 -v

?

[friyal]

No, I download http://www.youtube.com/playlist?list=PL63F0C78739B09958 successfully.

[phihag]

Mmm, can you make a public demo playlist that shows the problem? The initial failing request is the one to the youtube API, i.e. something like

https://gdata.youtube.com/feeds/api/playlists/PL63F0C78739B09958?max-results=50&start-index=0&v=2&alt=json&safeSearch=none

[friyal]

Oh, sorry, my fault, not yours. When I turned the playlist to be public, I didn't turn the videos to be public. So the problems stay here. But if you don't mind, may I ask if there is a way to retrieve private video's URL from a playlist when I'm the owner?

[jaimeMF]

I think that the extraction of private videos from privates videos is fixed (#1374), could you try with the latest version (higher than 2013.09.05), please?

[phihag]

With the switch to a different playlist extraction method, this should now all work. If it doesn't, please comment or open a new issue. Thanks!
