[Help] Video download decryption Unable to parse license - Check protobufs

[Bluesoul]

Hi Download Gurus,

I'm trying to download the following video, but i keep getting the error in l3.py (WKS-KEYS): unable to parse license - check protobufs.

Could someone please enlighten me? I've been hours trying without luck. Thank you so much in advance for your time



This is the video (You need to change location with VPN to India)

Hi,
your browser extension looks awesome, thank you for sharing it. I just installed it, could you share a guide/link of how to get the device file?

Thank you in advance!

Thanks for taking the time guys and look it up, could you tell me if this is the correct one?
I am filtering in Dev tools by "widevine".
if that "post" one is the correct one, what exactly do i need to copy? I just tried it with the same PSSH and copied the URL of the post file i am showing you in the pic but still get the same error:
unable to parse license - check protobufs

Thank you!

You need to update headers using curl of this url.

Awesome, thank you!

Could you help me with 2 questions please?

1. Do you happen to also know the best way to download after getting the keys with your extension?

2. Do I still need to emulate and get the files using android studio?

[Obo]

1. That's explained in the tutorial you mentioned in your first post.
2. No (should be clear if you read the tutorial...)

Also: if you continue to use WKS-KEYS as explained in the tutorial: don't copy the whole output of curlconverter into headers.py, but only the headers dict. No "import requests", no "requests.post". The headers.py file is included from l3.py, which you have to execute.

But clearly: I wouldn't bother using WKS-KEYS anymore. There are so many great tools out here in the forum you can use, and @larley's latest tool seems to be one of the easiest and best to use. Only use WKS-KEYS if you want to learn programming Python (even then: I wouldn't bother to extend WKS-KEYS...).

Thank you for your hints and you are right, with the extension it's much easier. If i do it with @larley's extension could you please tell me if i am getting it correctly?


1. itf i use @larley's extension, that means, i can skip steps 2-5 from this tutorial (https://forum.videohelp.com/threads/410399-Downloading-videos-from-Jiocinema-Step-by-Step-Guide)? If that's correct

2. I need a WDV file to chose in @larley's extension which has the private keys (files*.bin and *.pem) I got with the WVDumper from step 1 of the tutorial, how exactly could I do it if so?

Thank you in advance!

[larley]

1. Yes
2. Create a Widevine Device like so:

pywidevine create-device -k "path/to/device_private_key" -c "path/to/device_client_id_blob" -t "ANDROID" -l 3

[Bluesoul]

1. Yes
2. Create a Widevine Device like so:

pywidevine create-device -k "path/to/device_private_key" -c "path/to/device_client_id_blob" -t "ANDROID" -l 3

Awesome, thank you so much @larley, now it worked

I wanted to ask you:

1. What is the difference between using one of the CDM's you shared above and using the one i create with the android emulator in my own pc to load it in your extension?

2. Is it possible for you to make your extension also get the mpd url to copy it faster from there in a future version?

3. is there a way to batch download a serial without doing the whole process per episode? Or is there a more efficient way you already know of doing it?

Again thank you so much, your extension is the best!

[larley]

1. There's actually no difference between the CDMs itself, it's just easier to get them and there is a tiny chance that the public one might get revoked. There are also some physical device CDMs on here which you'd need for Peacock or DRMToday for example.
2. That's not possible because Chrome extensions for Manifest V3 don't have access to the webRequest API and MV2 will be revoked soon.
3. Not with this extension. You'd have to find some betch downloader script on this forum or ask somebody to do it for you (not me)

Gotcha, thank you mate. All the best
