DirecTV Stream DeviceID Mismatch Error

[Larsenv]

I'm trying to make a downloader to rip from DirecTV Stream. However, with my best efforts, I'm getting a error saying {"errorReason":"10062","description":"Mismatch in request information - Device","message":"DRM DeviceID Mismatch"}

What I don't understand is that the request headers match up to the device which Ive extracted the CDM from, which is Android on a emulator, I proxied the request from the emulator.

It seems to use a cert, and I added that to the mix, but it required headers for the cert.

Heres the request for the DRM license

headers = {
    "accept": "application/json",
    # 'accept-encoding': 'gzip, deflate, br, zstd',
    "accept-language": "en-US,en;q=0.9",
    "authorization": "<redacted>",
    "connection": "keep-alive",
    "content-type": "application/json",
    "flow_context": "activate_1730052493.396",
    "host": "api.cld.dtvce.com",
    "origin": "https://stream.directv.com",
    "referer": "https://stream.directv.com/",
    "sec-ch-ua": '"Chromium";v="130", "Microsoft Edge";v="130", "Not?A_Brand";v="99"',
    "sec-ch-ua-mobile": "?1",
    "sec-ch-ua-platform": '"Android"',
    "sec-fetch-dest": "empty",
    "sec-fetch-mode": "cors",
    "sec-fetch-site": "cross-site",
    "user-agent": "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/130.0.0.0 Mobile Safari/537.36 EdgA/130.0.0.0",
}

json_data = {
    "contentID": "4734",
    "contentType": "2",
    "identityCookie": "<redacted>",
    "authorizationToken": "<redacted>",
    "licenseChallenge": "<redacted>",
}

Here's the header for the cert

headers = {
    "accept": "*/*",
    # 'accept-encoding': 'gzip, deflate, br, zstd',
    "accept-language": "en-US,en;q=0.9",
    "connection": "keep-alive",
    "host": "stream.directv.com",
    "referer": "https://stream.directv.com/watchnow",
    "sec-ch-ua": '"Chromium";v="130", "Microsoft Edge";v="130", "Not?A_Brand";v="99"',
    "sec-ch-ua-mobile": "?1",
    "sec-ch-ua-platform": '"Android"',
    "sec-fetch-dest": "empty",
    "sec-fetch-mode": "cors",
    "sec-fetch-site": "same-origin",
    "user-agent": "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/130.0.0.0 Mobile Safari/537.36 EdgA/130.0.0.0",
}

Here's the code I wrote

def decrypt_content():
    license_url = "https://api.cld.dtvce.com/rights/management/mdrm/vgemultidrm/v1/widevine/license"

    # prepare pssh
    pssh = PSSH(
        "AAAAOHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABgSEBWvzdlJ4r7/P7MZ4yxCMV1I88aJmwY="
    )

    # load device
    device = Device.load(extracted_device)

    # load CDM from device
    cdm = Cdm.from_device(device)

    # open CDM session
    session_id = cdm.open()

    cert = requests.get(
        url="https://stream.directv.com/att.tv/wv/cert_license_widevine_com.bin",
        cookies=DRMHeader2.cookies,
        headers=DRMHeader2.headers,
    )

    print(cert.content)

    cert = cert.content

    cdm.set_service_certificate(
        certificate=cert,
        session_id=session_id,
    )

    # Generate the challenge
    challenge = cdm.get_license_challenge(session_id, pssh)

    DRMHeader.json_data["licenseChallenge"] = base64.b64encode(challenge).decode(
        "utf-8"
    )

    print(DRMHeader.json_data["licenseChallenge"])

    # send license challenge
    license = requests.post(
        url=license_url,
        headers=DRMHeader.headers,
        json=DRMHeader.json_data,
    )

    print(license.content)

    license = base64.b64decode(license.json()["licenseData"][0])

    print(license)

    # Replace invalid characters
    license = license.json()["license"].replace("-", "+").replace("_", "/")

    # Parse the license
    cdm.parse_license(session_id, license)

    # assign variable for returned keys
    returned_keys = ""
    for key in cdm.get_keys(session_id):
        if key.type != "SIGNING":
            returned_keys += f"{key.kid.hex}:{key.key.hex()}\n"

    # close session, disposes of session data
    cdm.close(session_id)

    # Return the keys
    return returned_keys

Remember, this is a paid service, so this thread is gone as soon as Baldrick discovers it.

I've had somebody request DirecTV support for WidevineFetch. All I wrote down here was "Widevine Device must be registered" and I remember that they sent some challenge (or similar) to the license server before playback to "register" the device first. This explains the "DRM DeviceID Mismatch" error you're encountering. I think WidevineProxy2 should work for DirecTV

[Larsenv]

Thanks, that seems to have done the trick to be able to get the key

Ive seen threads for paid services here, I didnt mean to break the rules, does it depend on what baldrick is able to find

[larley]

Actually yes, I think he's the only moderator on this forum, so only the threads that he's able to read can be locked

never mind
