The video player can be accessed through - https://plum-maxie-29.tiiny.site/

I have tried using WidevineProxy2 browser extension it does not get any keys.

I'm facing similar issue, but unlike the one that is mentioned on this thread, the video is AES-128 encrypted
https://breezy-cyan.tiiny.site

(there are 2 demo free to watch videos both using AES-128 encryption, one can create an account using temp mail for testing)

[2nHxWW6GkN1l916N3ayz8HQoi]

Your link is messed up for some reason. The 2 videos are here
https://www.parmaracademy.in/courses/56-parmar-english-batch

I have no idea how to extract the key but here are your videos since I just skipped over their hls aes mechanism with js injection.
https://www.swisstransfer.com/d/1a98a0cd-3aba-435d-afdf-fb29a33cb5f5

It's best you wait for a kind capable user to write a script for you since that's the proper easy to use solution

which streaming link you are using to get it download? the visible one is not working as it showing 8sec duration

[2nHxWW6GkN1l916N3ayz8HQoi]

which streaming link you are using to get it download?

None.

I don't know the decryption key, nor any mp4 URLs hidden in html. Uh, I don't think I made myself clear in the prev comment. By js injection I mean that I put my own code in their page, set the video to 8x-16x speed, and download their decrypted fragments one by one. I let the site do the decrypting client side since I can't understand their hls mechanism and do it myself. One video downloads in 15 min.

If it still doesn't make sense here's an example where I apply this strategy, just the code inserted and the context is different since there isn't 1 general working solution
https://forum.videohelp.com/threads/412993-how-to-download-a-video-of-higher-quality-f...x)#post2719620

Even if its' effective, it's convoluted and tedious. That's why I don't recommend it.

hi, i have a script.. it's downloading and decrypting, but the problem is i am not getting the audio, can you check the issue?? i am not good in python btw

[2nHxWW6GkN1l916N3ayz8HQoi]

Sure, you can post the script here or if you don't intend to publish it, private is good too.
Add use case example as well to know how to run it

Regarding the m3u8 url, just look for

and change it to

yes they are using AES-128 similar to graphy/spayee. I have sent a pm to larley since he has a repository on github regarding AES decryption.

Block the anti-debugger using ublock origin rule:

parmaracademy.in##+js(set, Function.prototype.constructor, function() { return function() {}; })
player.akamai.net.in##+js(set, Function.prototype.constructor, function() { return function() {}; })

Get the key and playlist directly from developer console (may have to wait very long due to errors):

var player = videojs.getPlayers()[Object.keys(videojs.getPlayers())[0]];
console.log(player.tech().hls.playlists.media_.segments);

The site is using video from akamai.net.in which is using appx.co.in and someone has already written script for such platform:

Hi, thanks for your response, how did you find the key here exactly? The anti debugger script that you sent doesn't work for me , and if I disabled breakpoints, I will not be able to set the breakpoint at the memory address. Is there any updated version of the ublock script?

[Attachment 88020 - Click to enlarge]

Also the github repository you mentioned, required "kstr" and "jstr" values which needed to be decrypted, but for me it shows empty kstr, any clue whats going on?
