yt-dlp: Cannot download video from udemy
Hi there,
I got 403 error when downloading course from udemy business. I used command:
yt-dlp -u udemy@abc.com -p password -P '~/Downloads' -o '%(playlist)s/%(chapter_number)s - %(chapter)s/%(title)s.%(ext)s' https://abc.udemy.com/course/ielts-vocab-builder-002/
I’m sure that the username/password in command is correct. Please see the log:
[debug] Command-line config: ['-u', 'PRIVATE', '-p', 'PRIVATE', '-P', "'~/Downloads'", '-o', "'%(playlist)s/%(chapter_number)s", '-', "%(chapter)s/%(title)s.%(ext)s'", 'https://abc.udemy.com/course/ielts-vocab-builder-002/', '-v']

I was just playing around with this and found a simple work-around, namely
--cookies-from-browser firefoxI don’t know that firefox is a necessary argument, but I think the cloudflare issue must be getting proc’d by some difference in
--cookies-from-browserand--cookies. It seems plausible udemy may be directly parsing the cookies files for the header linesI have not tried to modify the netscape-formatted cookies file to see if it changes behavior, just a shot in the dark.
Account shared. Answer from pukkandan: Cloudflare captcha is causing the issue. Will need to investigate further to find a solution
The workaround from @gamedazed provided few days ago does not work for me. Also it seems that Udemy Business is using AWS CloudFront now. It stopped working all of a sudden around May 14th / May 15th (relative to sun).
I want to watch Udemy video on mpv for studying and note-taking. I tested
2022.06.29and found some issues and workaround.udemy.py:L168-L171Udemy login popup is updated. So it needs to be updated. But after a few successful logins, I couldn’t log in. Udemy just returnend the login popup html. I don’t know why. Maybe Udemy restriction?
yt-dlpneeds to be updated inudemy.py:L132-L139udemy.py:L205_real_extractpasses wrongcourse_idto_download_lecture. It always gets403 Forbidden. Ifcourse_idis correct,yt-dlpwill download video properly. I wanted to make a PR but I couldn’t fix the 3 because I couldn’t pass playlist url which has realcourse_idto_real_extract.same issue using version
2022.05.18with v2021.10.22 I only get the “course: Unable to download webpage” error:
