mpd decrypting problem [unable to parse license - check protobufs]

[thej911]

Hi I'm New to this and I'm trying to learn how to decrypt mpd so i start testing on the following link:

https://bitmovin.com/demos/drm

I got the mpd file link :

https://cdn.bitmovin.com/content/assets/art-of-motion_drm/mpds/11331.mpd

PSSH:

AAAAW3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADsIARIQ62dqu8s0Xpa7z2FmMPGj2hoNd2lkZXZpbmVfdGVzdCIQZmtqM2xqYVNkZmFsa3IzaioCSEQyAA==

license url:

https://licensing.bitmovin.com/licensing

the headers i used:

import requests

headers = {
    'authority': 'licensing.bitmovin.com',
    'accept': '*/*',
    'accept-language': 'en-US,en;q=0.9',
    'content-type': 'text/plain;charset=UTF-8',
    'origin': 'https://bitmovin.com',
    'referer': 'https://bitmovin.com/',
    'sec-ch-ua': '"Not_A Brand";v="99", "Google Chrome";v="109", "Chromium";v="109"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
    'sec-fetch-dest': 'empty',
    'sec-fetch-mode': 'cors',
    'sec-fetch-site': 'same-site',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/109.0.0.0 Safari/537.36',
}

data = '{"domain":"bitmovin.com","key":"29ba4a30-8b5e-4336-a7dd-c94ff3b25f30","version":"8.104.0"}'

response = requests.post('https://licensing.bitmovin.com/licensing', headers=headers, data=data)

when i try to decrypt i get the following message:

unable to parse license - check protobufs

I really want to learn this so please Can anybody please tell me what I'm doing wrong?

I think the License URL was wrong !

after using the following License URL:

https://cwip-shaka-proxy.appspot.com/no_auth

I got the following keys:

--key ccbf5fb4c2965be7aa130ffb3ba9fd73:9cc0c92044cb1d69433f5f5839a159df
--key 9bf0e9cf0d7b55aeb4b289a63bab8610:90f52fd8ca48717b21d0c2fed7a12ae1
