New udemy mpd streams error!

[Sadomasochist]

Hi it seems they have changed something! So I can no longer download udemy encrypted videos! I know how to get keys and decrypt them but I cant even seem to download encrypted ones.

Help me download it via yt-dlp or Nm3u8DL-RE.

[stabbedbybrick]

Try including --referer and/or --user-agent with yt-dlp. If that doesn't work, try "--cookies-from-browser chrome".

If all else fails, you can simply download the mpd and open it locally with N_m3u8DL-RE:

Try including --referer and/or --user-agent with yt-dlp. If that doesn't work, try "--cookies-from-browser chrome".

If all else fails, you can simply download the mpd and open it locally with N_m3u8DL-RE:

For referer n UA in yt-dlp and cookies from chrome.

ERROR: [udemy:course] assets: Unable to download webpage: HTTP Error 403: Forbidden (caused by <HTTPError 403: 'Forbidden'>); please report this issue on https://github.com/yt-dlp/yt-dlp/issues?q= , filling out the appropriate issue template. Confirm you are on the latest version using yt-dlp -U



All else failed yes downloading it locally helps and works but very redundant for my downloader script to function!

If anyone can figure out! Let me know! Thanks!

I have the same problem, hope someone has a solution

I'm unable to get the keys, I get 403, any clue?
I dumped a CDM from Android studio, set the headers including the cookie values
Does it work with udemy?

Andriod studio thingy may work for tpd keys but it seems their chrome api has cloudfare issue for everyone. Wait till they fix it! or check the telegram group where they sell extensions, they offer free trial for one hour! so make use of it! If it is only few courses!

[Sadomasochist]

Just check if your cdm is revoked or not! just install pywidevine (pip install pywidevine) - make sure the scripts folder is in the env path! Then use pywidevine test pathtoyourwvd! it if is parsed then your wvd works!
