Description

I think Linkedin-Learning has changed its website design again, which is making youtube-dl unable to download any playlists from the website. I was trying the following among others.

youtube-dl --cookies cookies.txt https://www.linkedin.com/learning/c-plus-plus-essential-training-2

It fails for every course on Linkedin-Learning. I have an active subscription and I can view the videos online, but having downloaded the cookies after logging in, I wanted to have the course offline. Seems like youtube-dl fails to help me there.

version 2019.08.13 works for me, using firefox and This Cookie Addon to extract the cookie.txt file. Then use this code to download FULL COURSE videos well organized into specific chapters as subfolders into the Main folder: youtube-dl.exe --verbose --cookies .\cookies.txt "https://www.linkedin.com/learning/giving-your-elevator-pitch" -o "%(playlist)s/%(chapter_number)s - %(chapter)s/%(playlist_index)s - %(title)s.%(ext)s" --write-sub
