unable to parse license - check protobufs

[marioeivissa]

    challengeb64 = str(base64.b64encode(wvdecrypt.get_challenge()), "utf-8")

    json_data = {
        'authorization_token': '##########',
        'license_request_data':challengeb64
    }

    widevine_license = requests.post(url=lic_url, headers=headers, json=json_data)

my friend can you explain please why the aut token is like json, and why did you put license_request_data:challenge64?, just to understand a little bit more thanks

just curious, what's the encrypt method of the challenge?

Good afternoon, I get this error unable to parse license, I have the mpd and I have removed all the headers and I don't get keys. Can someone help me?

[Obo]

That error message is quite unfortunate, because it simply expresses that the library couldn't acquire a license. The cause is usually missing or wrong headers, authentication, ...

Switch to the more "modern" WKS-KEYS scripts that make use of the pywidevine library - found here: https://forum.videohelp.com/threads/411862-Beyond-WKS-KEYS

You'll get more precise error messages in return...

After downloading some videos the script says , unable to parse license , integrity error , how should i solve this ?

[clarses]

Hello, I am getting the same error. No matter what I have tried for days, it has not given me the code. I cannot understand where I am making a mistake or why it is not converting the code.
I tried all the software shared in the forum but the result was always unsuccessful for me. After entering pssh and license url with wks-keys, I always encounter the same error.

I need your helps

[Obo]

If you want help, you'll at least need to provide details. "Doesn't work" and "I've tried everything" isn't a good base for requesting help.

Also: read through the suggestions made even here in this thread, e.g. #34. And consider using some of the newer tools offered here in the forum, especially this one: https://forum.videohelp.com/threads/416316-%5BRelease%5D-WidevineProxy2-Extension-Bypa...s-Lic-wrapping

Or one of the other from the pinned threads.

I downloaded and tried all the software fixed in the forum but I did not get any successful results. My aim is not to download a video, just to watch a live broadcast via reproductor. Finally, I tried the wks here, but this time I get this error: https://forum.videohelp.com/threads/411509-WKS_KEYS-updated-protobuf-to-version-4
license request failed:
b'{"errorDetail":"token contains an invalid number of segments","errorCode":"validationError"}'

Sorry if I'm bothering everyone. I just thought maybe I could benefit from your experiences and achieve something. Thanks
