An Amazon movie (free with ads)

[CrymanChen]

Guys, I'm posting a new thread to try to seek help from y'all. It's about the Amazon.

Straight to the point, the movie is free to watch. [John Wick 3 - Parabellum](https://www.amazon.com/gp/video/detail/B07SZZNFRM)

PSSH:

License:

https://atv-ps.amazon.com/cdp/catalog/GetPlaybackResources

For convenience, I copied & sorted the cURL of the license request -> [cURL information](https://telegra.ph/cURL-information-05-26)

the main WV_Function is as below:

def WV_Function(pssh, lic_url, cert_b64=None):
    wvdecrypt = WvDecrypt(init_data_b64=pssh, cert_data_b64=cert_b64, device=deviceconfig.device_android_generic)
    challengeb64 = str(b64encode(wvdecrypt.get_challenge()),"utf-8")
    data = {"widevine2Challenge":challengeb64,"includeHdcpTestKeyInLicense":"true"}
    widevine_license = requests.post(url=lic_url, headers=headers.headers, params=headers.params, cookies=headers.cookies, json=data)
    
    print(f'\nLicense Body: {widevine_license.request.body}')
    print(f'Status code: <{widevine_license.status_code}>')
    print(f'License Response: {widevine_license.content}')

    license_b64 = b64encode(widevine_license.content)
    wvdecrypt.update_license(license_b64)
    Correct, keyswvdecrypt = wvdecrypt.start_process()
    if Correct:
        return Correct, keyswvdecrypt   
correct, keys = WV_Function(pssh, lic_url)

I added printing the Request Body and the Response to debug, and as I expected, there are some problems:

The server returned this:

{"Output":{"__type":"com.amazon.coral.service#UnknownOperationException"},"Version":"1.0"}

Any advice & help would be appreciated.

Not really sure if even the free things are okay to discuss, but I'd change 'json=data' to 'data=data'.

Also I don't use str(...challenge...)', I use b64encode(...).decode(). Maybe both work fine.

You'll also need to interpret the json that comes back.

Free contents which means that everyone can access are OK to discuss.

But I still wonder why this error occurred.

You can use Kigo Amazon Downloader, you can find it cracked, just Google it. With this software you can download any free video from Amazon encrypted and ready to play.

Are you sure it's free to watch?

It says "rent 3.99$, buy 13.99$"
