Help with RTS Play decription keys

[George7]

Hi,

First, I want to thank everyone for their help with CDM and decryption (specifically Cedric8528, A_n_g_e_l_a and [ss]vegeta.
While i've succeed in obtaining a CDM from an Android Emulator and in getting proper keys with WKS-KEYS to decrypt the files from some sites I have a hard time with RTS.ch and need some help.

params = {

data = '\b\x04'

response = requests.post(
    'https://srg.live.ott.irdeto.com/licenseServer/widevine/v1/SRG/license',
    params=params,
    headers=headers,
    data=data,
)

On others streaming site i usually get an 'Authorization Bearer' token that is also part of the header but i can't find any in the Dev Tools network tab on RTS.
If I try with CDRM-Project, I get the following Error 403: {"code":130301,"message":"Content is not available in this location."}
Obviously i did something wrong and would appreciate if someone can point me in the right direction.

Kind regards,

Use your own CDM and maybe WKS and decrypt yourself. this site is very easy. Not all sites uses Auth token and etc.

Your keys:

Thank you but I'm not asking for keys. I just want to know where my mistake is in the info i provided and where to look for what i need to decrypt.

For RTS, you don't need a header, PSSH and license are enough.

Edit : And a good VPN of course ^^

You need to make the request from Switzerland, the Lic server only works from there it seems. So your error indicates you are not there or your VPN gets detected.

Thank you very munch for the hint, i've used an empty header and it worked perfectly. I made it more difficult than it was

HEADER.PY

import requests

headers = {
}
