Problème protobufs

[alex007]

Hi

I tried to uses WKS KEY in command line

But when I start this commande I have :

unable to parse license - check protobufs



PSSH: AAAAMHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABAiCDE0MD MyODI5SOPclZsG
License URL: https://widevine-proxy-m.prod.p.tf1.fr/proxy?id=14032829&rn=1&ssc=403cc620-f384-49b2-a...4&e=1698569221

My URL of my mpd file is : https://vod-das.cdn-0.diff.tf1.fr/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJjaXAiOiI5MS4...m/14032829.mpd


Thank you for your help

And what is in headers.py? My guess would be nothing. Read information in the stickies at the top of this forum's page, especially https://forum.videohelp.com/threads/407216-Decryption-The-Dungeon-of-Despair

This is the content of my file headers.py

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/119.0',
    'Accept': '*/*',
    'Accept-Language': 'fr-FR,fr;q=0.5',
    # 'Accept-Encoding': 'gzip, deflate, br',
    'Referer': 'https://prod-player.tf1.fr/',
    'Origin': 'https://prod-player.tf1.fr',

}

It's probably missing a relevant header. What's the video URL? From mpd and license URL alone it's quite hard to verify.

Edit: @cedric8528 obviously is right - should've tried that first by myself. In that case something more fundamentally is wrong at your side, because it doesn't matter what you put in headers here.

You don't need headers to get keys

Hi Cedric

Thank you but I have the same problem.

How do you genrate key?

What version of WIN-KEY do you need?

[lomero]

maybe your cdm is dead ...

[cedric8528]

works with all versions of WKS-Keys

If you are not in france, maybe it's a problem of VPN....

and as Lomero says ...also your Cdm..

[alex007]

I live in france. I have not a VPN

How to reinstall CDM if he is dead ?

[Obo]

Works from outside France (at least from Germany)...

[cedric8528]

put new cdm files inside

[alex007]

I have this version
https://files.videohelp.com/u/301890/WKS-KEYS.zip

Where do you find a new file for CDM ?

[Obo]

Look at the links in User @Karoolus signature.

As an alternative to the wks-keys scripts "l3.py" script you could use the following standalone script, which utilizes the official pywidevine module (pip install pywidevine):

import requests, sys, headers
from pywidevine import (
    Device,
    Cdm,
    PSSH
)

def obtain_keys(pssh, url, headers, params, cookies):
    device = Device.load('my.wvd')
    cdm = Cdm.from_device(device)
    session_id = cdm.open()
    challenge = cdm.get_license_challenge(session_id, PSSH(pssh))
    license = requests.post(url     = url,
                            data    = challenge,
                            headers = headers,
                            params  = params,
                            cookies = cookies)
    license.raise_for_status()
    cdm.parse_license(session_id, license.content)
    keys = cdm.get_keys(session_id)
    cdm.close(session_id)
    decryption_keys = [f'{key.kid.hex}:{key.key.hex()}' for key in keys if key.type == 'CONTENT']
    return decryption_keys

if len(sys.argv) > 1:
    pssh = get_pssh(sys.argv[1])
else:
    pssh = headers.pssh # input('\nPSSH: ')

lic_url = headers.lic_url # input('License URL: ')
try:
    params = headers.params
except:
    params = {}

try:
    cookies = headers.cookies
except:
    cookies = {}

keys = obtain_keys(pssh, lic_url, headers.headers, params, cookies)

for key in keys:
    print('--key ' + key + ' \\')

It also relies on the headers.py script containing the headers array along with possibly cookies, params and pssh variables. PSSH can be passed as command line parameter as well. You'd need to build your own my.wvd file by using the "pywidevine" script which gets installed by "pip install pywidevine". After that you can throw away the rest of the wks-keys scripts.

You'll find more information about the pywidevine module here: https://forum.videohelp.com/threads/411862-Beyond-WKS-KEYS

It work great.
I changed cdm

Thank for responses
