I found the code on a French forum.

https://www55.zippyshare.com/v/bZNmE2S8/file.html

[ElCap]

how are you running it when you see the error?

[Tiflo 62]

Running using python3 app.py

[Tiflo 62]

I run the webpage and after completing the pssh, url and build info here is the error message:

You should recheck the url (video link) and find the license link with the POST method, the get method link is wrong.

[Tiflo 62]

Thank you for your help.

I checked but with "widev" or "license" as keywords I only found this url:

https://rbm-rtbf.live.ott.irdeto.com/licenseServer/widevine/v1/rbm-rtbf/license

[Attachment 66919 - Click to enlarge]

[ElCap]

you need to copy the full url with the query parameters
right click license request - copy link address

[Tiflo 62]

Thank you ElCap, it works now!
Thanks to lomero for helping me by PM too!

Hello to all the respected mods and members of the forum.
Need some help in decryption of the DRM Protected video.

Iam trying to download this : https://www.rtbf.be/auvio/detail_moto-gp-gp-japon?id=2942471

As per the relevant instructions provided by @[ss]vegeta and all other members, i have managed to get hold of the encrypted audio and video, but when joining the same using ffmpeg, the result is the video is all blanked out and only the audio is playing in the background. This is the error i get:

[gadumuc]

I think the audio codec ext must be m4a

from
ffmpeg.exe -i cv_dec.mp4 -i ca_dec.mp4 -c copy final.mp4

to
ffmpeg.exe -i cv_dec.mp4 -i ca_dec.m4a -c copy final.mp4

check the files you downloaded for correct extensions

getting the same error even after doing this, i.e. :

Anything else you suggest? or is there something with the decryption that didn't go well, and hence maybe i need to try again to decrypt? Thanks

Key is correct. Everything downloads fine, decrypts fine with the key you got.
The only conclusion is: there's a bug in the latest ffmpeg version you appear to be using.
So, try an older ffmpeg.
Like this one, for example.
https://we.tl/t-JYLVdUJEJh
If this is the case, don't just be happy with the fix of your problem, go the extra mile and report the bug to the developer of that ffmpeg.

Hmm, I downloaded the exact version of your ffmpeg, still decrypts fine.
Maybe you should try to redownload the video. What's the size of the encrypted video and of the decrypted one?

[Attachment 67008 - Click to enlarge]

Video sizes are same as seen in your screenshots. But by using your ffmpeg, it somehow works. Thanks again for helping out.

Further, video also got successfully decrypted using @karapuz method. So, a thank to him as well.

As per your advise i have reported the bug to the developer.

[dabou]

How have you been able to fully succeed by running locally `python3 app.py` ?

I grab the PSSH data from the mpd file (using chrome console - network where files are filtered using "mpd") under the following tag

<MPD ...
  <Period ...
     <AdaptationSet ...
        <ContentProtection
        schemeIdUri="urn:uuid:EDEF8BA9-79D6-4ACE-A3C8-27DCD51D21ED">
        <cenc:pssh>AAAAXHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADwIARIQeDLff7vYQ....</cenc:pssh>
      </ContentProtection>

I verified the PSSH base84 using - https://integration.widevine.com/diagnostics and got

{
	"algorithm":"AESCTR",
	"keyIds":["eDLff7vYQIKfuaFVLv5iOA=="],
	"provider":"usp-cenc",
	"contentId":"ZURMZmY3dllRSUtmdWFGVkx2NWlPQT09",
	"trackType":"",
	"policy":""
}

I got the license URL using Chrome console - network and full request (= copy link address).

But when I click on the "send" button, I got the error "No CDM found". How can fix that ? Do we have to run a CDM server locally - how ?

How can we pass "build info" within the screen ?

hi

for some reason getwvkeys.cc stopped letting me in, so I am not able to retrieve decryption key for the movie below;

https://auvio.rtbf.be/media/flair-de-famille-rouge-sang-3008483

Can anybody share alternate method for obtaining this key?

TIA

Simply use wks-keys

try this key :

Good afternoon, forum!

I am a complete newbie with a very limited use case or knowledge of how to extract and decrypt video files from websites. The rtbf.be website holds a rare performance from one of my favorite 80s synthpop groups. If it's not too much trouble, would one of the forum members kindly download the video linked below in the best available quality (I believe it's 720p)?

https://auvio.rtbf.be/media/ligne-rock-2651474

I've asked another member privately for help, but their prior working method didn't work.

"Normally, right-clicking on the video and "Inspector" within Edge (or Chrome, or Firefox), I should be getting a .mpd url, a cssh contained in the .mpd, and a .lic url, all of which I then use to make a key. Still works for any news flash, but not for this "Soft Cell" video... All I found is the .mpd url. The rest must be hidden or something... This is interesting..."

Thank you very much! I look forward to any response!

Firstly identify MPD URL for example via StreamDetector plugin in Firefox.

Then check available streams:

Here you go: https://mega.nz/file/vvQhFBLQ#7SnAbfZQEEhCTyqUBCRi2bNYpz6DYFoxCQ6pnoDLLtc

The video wasn't even encrypted. I guess the person you asked was so focused on getting the key that the forgot to give it a test run beforehand
