[Release] Widevine L3 Guesser Extension-Works in 2024 Firefox/Chrome All OS

[white_snake]

Hi,

I´m trying to get the keys from the provider NOS.TV from Portugal.

It doesn´t work, i know that is not some kind of bug neither errors, but something is missing.

Reading the networks packets i see that the error 401 Unauthorized is present.

Here´s the info

Try with only the nv-authorizations header. The right license url should be:

https://nos71zv1.anycast.nagra.com/NOS71ZV1/wvls/contentlicenseservice/v1/licenses

Response should be in json, although that's not your problem (yet).

Also this is not the right thread to post your problem to, find another thread that talks about NOS, open another one, or PM me.

in order to work properly I have to send complete json because it contains if I remember correctly the PID, but I am not sure

[Announcement]

Started beta test of new version of this extension🎉
After beta testing has done, I will focus be on developing new version, and legacy versions will not be actively developed.
You can try new extension here:
https://github.com/FoxRefire/wvg/tree/next

In new version, it dropped WVCore.Server and works with Pyodide+Pywidevine.
Therefore, extension works standalone and doesn't need external API setup.


Of cource, you can still continue using of legacy version after beta testing is done here:https://github.com/FoxRefire/wvg/tree/legacy

I am confused about the file called device.wvd, where do I get that at? or is it one of the files like device_client_id_blob or device_private_key and just rename one of them to device.wvd? thanks

Try use this generate a wvd file

pip install pywidevine
pywidevine create-device -t ANDROID -l 3 -k device_private_key -c device_client_id_blob

@FoxRefire,
Go to your profile settings and turn off all PM's. This is an easy fix and I think that it will benefit you.


Thanks for the share and your patience.

[FoxRefire]

Does that include the DM I sent you?

[FoxRefire]

> Does that include the DM I sent you?
Nope,I appreciate you for providing the scheme for the old version of the extension and for your suggestions of UI improvement.
However, I am not going to merge your UI improvement suggestions into my code, as I was a bit unsatisfied with them.

[FoxRefire]

[Announcement]
DRMToday scheme has also been added to the new version of the extension.
https://github.com/FoxRefire/wvg/commit/f98c2b1781770c96d507f7800d87689fa1e305b0

My version of your "legacy" extension attempts to automatically select the correct license server, do you want that code snipper or not needed?

[skipmack46]

@FoxRefire any thoughts about adding sites that has M3u8 + Keys to the guesser to pull from those type of streams? thanks

[FoxRefire]

The stream type, such as MPD or M3U8, does not matter if the extension is available at the site or not.
What is important is whether the license wrapping scheme used by the license server is supported by the extension.
https://online.familyclub.jp/s/jno/page/live_player_test
For example, this site uses m3u8 for its streaming format, however which uses common licensing scheme, so extension is available to use.

And Rule 2, You must submit scheme when specific website inclusion request.
Schemes is in python/schemes directory.

the extension is available to use, it displays the PSSH and License server, but when I click on guesser, it will not display the key, the Guesser works on other sites that have MPD, and not this site that uses M3u8 so far. any help on this would be great.

Works on my side.If not for you, this is bug.
Read the rules in the first post and do what you should do.

[skipmack46]

I never said that site you posted didn't work, I am saying the one I am trying to get to work with M3u8 + keys is not working.

Yes,Automatic detection of license URLs is one of the features I plan to add in the future.
Thanks Karoolus.
