drm in francetv

[ludo]

Good evening,
I have a video :https://www.france.tv/enfants/six-huit-ans/tortues-ninja-les-chevaliers-d-ecaille/sais...chnodrome.html

le mpd:https://cloudingest.ftven.fr/3c05cd49b9666/269ac3a6-efcc-4b89-8ed4-64810da8aa29-171820...m/manifest.mpd

I can't find the license (and maybe the headers) to use http://108.181.133.95:8080/
Thank you for your help to explain me where to find license

First time seeing DRM on francetv content. Here is the key :

269ac3a6efcc4b898ed464810da8aa29:c9fd40e2225059bf1c172ad56e7927bd

Download command :

The license url :

https://api-drm.ftven.fr/v1/wvls/contentlicenseservice/v1/licenses

You have to add nv-authorizations in the header. Getting keys with CDRM or others projects like those one might not work due to geo restrictions.

I find the nv-authorizations but I have an error :ERROR
Wrong headers: while scanning a simple key in "<unicode string>", line 2, column 1: eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1 ... ^ could not find expected ':' in "<unicode string>", line 2, column 412: ... Eaz3rpGJmrfFFE14a_ciG4ayA1ZEUodM ^

You are using http://108.181.133.95:8080/ to get keys ? I never used that sorry

[ludo]

what tools do you use?

[aqzs]

I use pywidevine.

Here is a small script that wll give you download command based on the video url (with or without DRM) :

from pywidevine.cdm import Cdm
from pywidevine.device import Device
from pywidevine.pssh import PSSH
import requests
from slugify import slugify
import xml.etree.ElementTree as ET
import re

def getpssh(url_mpd):
    psshs = []
    response = requests.get(url_mpd)
    root = ET.fromstring(response.content)
    for i in range(20):
        for j in range(20):
            for k in range(20):
                for l in range(20):
                    try:
                        if root[i][j][k][l].text not in psshs and len(root[i][j][k][l].text) > 70 and len(root[i][j][k][l].text) < 190:
                            psshs.append(root[i][j][k][l].text)
                    except:
                        pass
    for pssh in psshs:
        return pssh

def getkey(pssh, lic_token):
    headers = {'nv-authorizations': lic_token}
    pssh = PSSH(pssh)
    lic_url = 'https://api-drm.ftven.fr/v1/wvls/contentlicenseservice/v1/licenses'
    device = Device.load(DEVICEPATH)
    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)
    keys = []
    for key in cdm.get_keys(session_id):
        if key.type=='CONTENT':
            keys.append(f"{key.kid.hex}:{key.key.hex()}")
    cdm.close(session_id)
    return keys


def getvideo(ID):

    data = requests.get(f'https://k7.ftven.fr/videos/{ID}', headers=headers, params=params).json()
    mpd_url = data['video']['url']
    name = slugify(data['meta']['title'] + '.' + data['meta']['pre_title'], separator='.', lowercase=False)
    if 'drm' in mpd_url:
        pssh = getpssh(mpd_url)
        TOKEN = requests.post('https://k7.ftven.fr/drm-token', headers=headers, params=(('v', '2'),), json={"id":ID,"drm_type":"widevine","license_type":"online"}).json()['token']
        key = getkey(pssh, TOKEN)
        print(f"""N_m3u8DL-RE "{mpd_url}" --save-name "{name}" --select-video best --select-audio all --select-subtitle all -mt -M format=mkv  --log-level OFF --key """ + ' --key '.join(key))
    else:
        print(f"""N_m3u8DL-RE "{mpd_url}" --save-name "{name}" --select-video best --select-audio all --select-subtitle all -mt -M format=mkv  --log-level OFF""")

# urlvid = 'https://www.france.tv/enfants/six-huit-ans/tortues-ninja-les-chevaliers-d-ecaille/saison-1/6137147-irma-se-fait-remarquer.html'
DEVICEPATH = "device.wvd"
urlvid = input('Video url: ')
r = requests.get(urlvid)
matches = re.findall(r'"videoId":\s*"(.*?)"', r.text)
if matches:
    videoid = matches[0]
    getvideo(videoid)

You can use this much simpler script if you just want the keys :

from pywidevine.cdm import Cdm
from pywidevine.device import Device
from pywidevine.pssh import PSSH
import requests
lic_token = input('token: ')
headers = {'nv-authorizations': lic_token}
pssh = input("PSSH? ")
pssh = PSSH(pssh)
lic_url = 'https://api-drm.ftven.fr/v1/wvls/contentlicenseservice/v1/licenses'
device = Device.load("device.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)

[ludo]

the script not work : python3.10 pywidevine.py
Traceback (most recent call last):
File "/home/Bureau/N_m3u8DL-RE_Beta_linux-x64/pywidevine.py", line 1, in <module>

The script works for sure. Rename it other than pywidevine, it's the name of the library you are using, you shouldn't name a file the same as a lib, it's confusing for python. Since you never used pywidevine before install it using :

pip install pywidevine

In the code I provided you also have to change the path of device.wvd with your own one. You can get a CDM following this thread : https://forum.videohelp.com/threads/408031-Dumping-Your-own-L3-CDM-with-Android-Studio or grabbing one from here : https://forum.videohelp.com/threads/413719-Ready-to-use-CDMs-available-here%21

I use second link I download private key client id
the script :import sys

from pywidevine import Device

if len(sys.argv) < 2:
print(f'usage: {sys.argv[0]} <private-key-file> <client-id-blob> or {sys.argv[0]} <file.wvd>')
sys.exit(1)

if len(sys.argv) >= 3:

with open(sys.argv[1], 'rb') as f:
private_key = f.read()
with open(sys.argv[2], 'rb') as f:
client_id = f.read()

device = Device(
private_key=private_key,
client_id=client_id,
type_=Device.Types['ANDROID'],
security_level=3,
flags=None)

else:
device = Device.load(sys.argv[1])

print(device)

I have an error: python3.10 device private_key.pem client_id.bin
Traceback (most recent call last):
