[Udemy] No video formats found #30382

Closed RevilionDev closed 2 years ago

RevilionDev commented 2 years ago

My Errors Output:

youtube_dl.utils.DownloadError: ERROR: No video formats found; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

Any Idea to fix this?

Udemy's "No video formats found" is duplicate of #29925. Maybe only you can do now is to ignore errors with -i.

I think this issue is caused by the fact that Udemy does not provide links for all the videos on of the project on the landing page of the project, only the first few. I was doing some research and I was able to get the it to work for the first few files that have links on the project page, but as soon as those links disappear youtube-dl stops working. Sounds like it may be out of youtube-dl's hands on this one, which is a bummer.

Example: https://www.udemy.com/course/understanding-typescript/

The course items aren't extracted from the page, but using the https://www.udemy.com/api-2.0/courses/%(course_id)s/cached-subscriber-curriculum-items API endpoint. Perhaps this returns different result sets depending on the login used, etc. Checking at the API site I also see that this API endpoint isn't documented; maybe https://www.udemy.com//api-2.0/courses/%(course_id)s/public-curriculum-items/ should be used instead.
