Is downloading from RMC Découverte is not possible anymore ?

[fl0b]

I'm trying to download a video but i'm not able to decrypt it.

I was able to download the video with the good length but no audio and video is still encrypted. Thank you for your help!

Hi,

For RMC, there's only one key

try this key:

aa8be47a53db29b0e0533b28450a1cbb:1a1027b7e1c097a80e4bd4522c8ea4e4

Keys generated with cdrm-project:

The keys cached by cdrm-project for rmc are not good you should only have one key as @IceM said.
Here is a script to retrieve the key :

from pywidevine.cdm import Cdm
from pywidevine.device import Device
from pywidevine.pssh import PSSH
import requests

headers = {
    'customdata': 'CUSTOMDATA',
}

pssh = input("PSSH? ")
pssh = PSSH(pssh)
lic_url = 'https://ws-backendtv.rmcbfmplay.com/asgard-drm-widevine/public/licence'

device = Device.load(r"file.wvd")
cdm = Cdm.from_device(device)
session_id = cdm.open()
challenge = cdm.get_license_challenge(session_id, pssh)

licence = requests.post(lic_url, headers = headers, data=challenge)
licence.raise_for_status()
cdm.parse_license(session_id, licence.content)

for key in cdm.get_keys(session_id):
    if key.type=='CONTENT':
        print(f"\n--key {key.kid.hex}:{key.key.hex()}")

cdm.close(session_id)

You have to get your own .wvd or find one on the forum and change the value of CUSTOMDATA in the header.
The key provided by @IceM is the right one.

Thank you @aqzs, i will try your script, i have to figure out how to generate this .wvd file but i saw a tutorial doing that using an android emulator, i will try that when i get some time.

My bad @IceM, a character at the end of the key was missing. Thank you for the list, i see that there's a bunch of CDMs do i have to write a script to to test them one by one ? is there a way to check the key without downloading the video ?

take 2 or 3 to test if they're not blacklisted

To test the validity of the key, the easiest way is to download the video in low resolution

[fl0b]

Good idea, i'll try that.

Hi! It used to work, but now, when I download videos using this key, the videos are completely scrambled... It looks like the key has changed... Could you tell me how to find the key of RMC BFM Play, please?

[cedric8528]

the key is always the same.

Thank you! The end of my key was wrong. I retried using the key you posted, and the video is now readable

Hi, do you know if the technique still works? Here it stopped working, with the same key. I'm truying to download this TV show. For instance, this command returns an error message, and the video is scrambled:

Just out of curiosity, how did you find the new key? Any tutorial?

[calande]

Thank you cedric8528, I bookmarked it. It's a procedure that takes a significant amount of time to go through, but I may resort to it in the future.

[cedric8528]

Yes a lot of time!

Just 2 minutes if you read carefully the post.

It's an addon like the other ones for your browser

Just install and put L3 cdm that you can find in this thread below

https://forum.videohelp.com/threads/417425-Real-Device-L3-Cdms

Launch your video and you will get keys and command to download.
