Auvio - get KEY

[stef157]

Hello everyone!

As an introduction, I want to tell you that I spent several hours experimenting after reading various articles on the forum and other sites.

This concerns the Auvio platform (accessible for free with an account in Belgium) - https://auvio.rtbf.be/emission/trentenaires-24976.

When I look at the HTTP requests, I was able to find the MPD file.
I was able to (I think) find the license file.
And in the MPD file, I extracted the PSSH string.

On this website, https://cdrm-project.com, I entered the information, but I'm getting an "init data" error.

Could you please indicate my mistake or what I could have done to obtain the encryption keys (there are 24 episodes in the second season)?

Thank you for already taking the time to read me!

Thanks

but I'm getting an "init data" error.

Could you please indicate my mistake or what I could have done to obtain the encryption keys (there are 24 episodes in the second season)?

Here is the key for episode n°1 : --key 08da377b4de048fca343bc3cc92d02b8:20503f4148a274235 20107437421a917
And here the link for your episode : https://www.transfernow.net/dl/20240422TKYIELOy.
To obtain the key you need a CDM (read sticky threads how to obtain one with android emulator or grab one from the forum) and you can use the following script :

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

import requests

headers = {'accept': '*/*', 'accept-language': 'fr-FR,fr;q=0.9', 'origin': 'https://auvio.rtbf.be', 'priority': 'u=1, i',  'referer': 'https://auvio.rtbf.be/', 'sec-ch-ua': '"Chromium";v="124", "Brave";v="124", "Not-A.Brand";v="99"', 'sec-ch-ua-mobile': '?0', 'sec-ch-ua-platform': '"macOS"', 'sec-fetch-dest': 'empty', 'sec-fetch-mode': 'cors', 'sec-fetch-site': 'cross-site', 'sec-gpc': '1', 'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 Safari/537.36',}

params = (
    ('contentId', CONTENTID),
    ('keyId', KEYID),
    ('ls_session', TOKEN),
)

pssh = input("PSSH? ")
pssh = PSSH(pssh)
lic_url = 'https://rbm-rtbf.live.ott.irdeto.com/licenseServer/widevine/v1/rbm-rtbf/license'

device = Device.load(r"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, params=params, 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 need the replace device.wvd with your own one and change CONTENTID, KEYID, TOKEN that can be found in the licence request :

I could make a script to do all the work but I don't have time tonight (send me a pm if you want that I make one)

[white_snake]

Cdrm-project actually worked with it. You only need to input PSSH, which in this case is:

and license url:

https://rbm-rtbf.live.ott.irdeto.com/licenseServer/widevine/v1/rbm-rtbf/license?contentId=3026178_6BA97Bb&keyId=08da377b-4de0-48fc-a343-bc3cc92d02b8&ls_session=eyJ0....truncated

No headers needed.

params = (
    ('contentId', CONTENTID),
    ('keyId', KEYID),
    ('ls_session', TOKEN),
)

You need the replace device.wvd with your own one and change CONTENTID, KEYID, TOKEN that can be found in the licence request :

[Attachment 78546 - Click to enlarge]

But why would you pass the CONTENTID, KEYID, and TOKEN parameters separately like that when you could just take input for the whole license url, which already contains all of them? Seems like a clunky way to do it in my eyes, unless you were to expand the code to process urls in batch (or to have the page url as input).

Hello white_snake,
Hello aqzs,

Thanks for you help !

I understand what's my error with CDRM - I don't take the "good" PSSH…
I've tried with the correct one and it's OK, so I'll do for the other one.

@white_snake, all the link is the first season - not the second one.

@white_snake and @aqzs, it seem that there is a modification on the files.
Now, each MPD doesn't content the PSSH and the license work with "OPTION" method and not anymore with a "POST".

The name of the file is not licence anymore, but play.

Could you confirme that it's correct and not just I'm doing it bad ?

Thanks

Nope, everything is exactly the same as I described yesterday. You seem a little confused, make sure to read the sticky threads in this section of the forum to have a better understanding of how this works.

Ok, I'm definitely doing this wrong.
Are you able and kind enough to extract the episodes of the second season for me?

Thank you for implication and help

I thought you meant you needed the first season this whole time, my bad.

Then you're right about these links being different, but the good news is that the second season videos have no DRM at all, you can just grab the .mpd url and feed it to N_m3u8DL-RE or any other downloader:

The Stream Detector browser extension might be helpful here or you could even try to use yt-dlp and give it the page url directly, maybe with cookies:

yt-dlp --cookies-from-browser chrome https://auvio.rtbf.be/media/trentenaires-trentenaires-s02-3173922

Great, thank you for the information and the time taken to explain everything to me.
It is very pleasant.
