widevine-l3-guesser VS widevine-L3-WEB-DL-Script

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.

try using this

i know that in an older version of this script it would show each bitrate in the mpd, but now it should just choose the highest one

Ive tried using this but it I just cant get it to work

While I haven't used it I believe that's what this does.

if it uses widevine https://github.com/parnexcodes/widevine-L3-WEB-DL-Script

here u go

gonna link this script, makes downloading from a lot of sites much easier

Note from OP: I got this script to work with Amazon. Once the Widevine guesser successfully brute forces the key, copy every line that has a key, and make sure to grab the content_key_decryption.js:251 part too. Then in the folder make a file called "key.txt" and paste them in. Each line should be in the format of "content_key_decryption.js:251 WidevineDecryptor: Found key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx (KID=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx)" After that I checked the mpd files like in the above tutorial to make sure it has matching KIDs, and then copied the link to that one to use in the script.

Script Updated : https://github.com/parnexcodes/widevine-L3-WEB-DL-Script Instructions have changed , check readme.
