udemy-dl VS widevine-l3-guesser

Found something ir the AUR, but the last update was on 25/05/2021, and it point to this github link.

I tried this once a day, but always got 403 forbidden error. The udemy-dl repo has been archived, and the author won't support it any more. Can anyone here kindly help? Thank you!

If the course doesn't use DRM then https://github.com/r0oth3x49/udemy-dl otherwise https://github.com/Puyodead1/udemy-downloader and https://github.com/Satsuoni/widevine-l3-guesser with downgraded CDM to 2209 (might stop working on Udemy in the future though, but it still works for now)

Thanks for the response. I was looking at using Udemy-dl https://github.com/r0oth3x49/udemy-dl and downloading the courses using the access token in the cookies.txt file instead of logging in using my account details. Would this be safer? I might try using IDM and see if anything happens if I download 1 course

udemy-dl is a good option (here I published the steps)

Ever since Udemy encrypted their videos, most downloader have died. Most Notably Udeler https://github.com/FaisalUmair/udemy-downloader-gui and Udemy-dl https://github.com/r0oth3x49/udemy-dl

or you can try https://github.com/r0oth3x49/udemy-dl

Web-DL and Web-rip are different things done differently. Web-DL requires using scripts that utilize cdm keys to download the webstream. I have no idea if this script works anymore, but this script can (or could) extract l3 cdm keys to use for downloading https://github.com/Satsuoni/widevine-l3-guesser. Webrip involves using hdmi splitters to record the stream.

If they have DRM you need to find the keys using a Widevine Guesser, then download the encrypted file and decrypt it using either ffmpeg or mp4decrypt.

the widevinedumper script is a bit tricky, would be easier if you download the code for widevine-l3-guesser, open the content_key_decryption.js file, on line 106 you should see this, edit it with your own key, then add the extension to chrome

If the course doesn't use DRM then https://github.com/r0oth3x49/udemy-dl otherwise https://github.com/Puyodead1/udemy-downloader and https://github.com/Satsuoni/widevine-l3-guesser with downgraded CDM to 2209 (might stop working on Udemy in the future though, but it still works for now)

only downside is that you have to provide the decryption keys, the main way was using this extension https://github.com/Satsuoni/widevine-l3-guesser but google updated their DRM recently which broke it, not sure if it still works on udemy if you downgrade to the old CDM version or not.

> Is that even possible for Spotify at this point?

Spotify are using Widevine on their web client, which is considerably more annoying to deal with than the encryption method used in the files fetched by Psst.

Nothing is stopping them from only serving files from the endpoint that serves Widevine protected files.

Then again, Widevine L3 has been broken[0], Google just keeps rotating the private keys used in the content decryption module.
