[solved] need information on widevine drm

[reel]

Hello. I am new to widevine drm. I have been working on the widevine drm system for a while now. I have used the python pywidevine project to send a license request to the license url. The server responded with -1010 error. I assume that is caused by me using CDM which is for android. I have some questions:

1. Are there any browsers out there that expose the decryption keys?
2. Can python pywidevine project be used to send an Android app/app platform license request and receive a proper license response instead of error?

It seems it is as I assumed that the issue was using the Android CDM. I did not know about Chrome CDM. I asked Novia about this site's widevine drm earlier and he mentioned Chrome API without the CDM part. So, that threw me off. When he mentioned the Chrome CDM below I went and searched and found about it. Thanks. I am currently trying to find a working Chrome CDM. If anyone got a working one and does not mind sharing please feel free to PM. Thank you.

In general:

1. No.
2. Yes.

There are sites that require you to use a L1 CDM or CDM with valid VMP, but if this applies to the site you are trying: I don't know. Usually sending correct headers is crucial for the license request.

1010 error means "Invalid track type.", whatever exactly that means...

Edited.

I've already told you that you need chrome cdm,web doesn't support android devices,app side does!

Issue is solved.

This website doesn't even use widevine license. Content is obtained via : https://h5vv6.video.qq.com/getvinfo which is encrypted (base64 + encryption) (m3u8 is in raw here, that is why you can't find it in network tab). Try to look at : e.onGetInfoOver = function(t)

Even when trying with chromecdm I'm getting :
