Need help decrypting cloudfront video and audio

[lazur9]

I downloaded the video and audio, and then used mp4decrypt but couldn't decrypt the files.

Here are the URLs for the video and audio:

https://d1v1gqjht5uu1.cloudfront.net/media/ITRifYwX2b3xV/3c4f1988/video_8838_1080_227.mp4

https://d1v1gqjht5uu1.cloudfront.net/media/ITRifYwX2b3xV/3c4f1988/audio_1413_0_128.mp4

The key used: 5277cc9cc08b5c58b6e12d5e72e8bac0:956dfe5cc16de4fe9 d61f9f657396876

I think the key is wrong and it would be helpful if you could provide new keys for this.

P.S. I am new to this so don't have enough knowledge on how to create L3 CDM. Also, can a single key decrypt all of the videos from a playlist from Cloudfront?

i think the key is not correct

kid from your video
using mp4dump

better share your video url here

This is the .mpd url:

https://d1v1gqjht5uu1.cloudfront.net/media/ITRifYwX2b3xV/3c4f1988/stream.mpd

Video and audio stream have different KIDs, respectively: 8f3bf9972afd53898924e104ec749a99 and 57ed68551be559b3959dd5f823fc16da, so the key you provided is not the right one. Post the video page url.

The videos are from an online course so it's not visible without logging in.

your key is wrong
that is why you can't decrypt your video & audio
you have to find the right key

Alright thanks, I have some doubts I want to clarify as I am a newbie on this.

1. Can the videos be decrypted later if I don't have access to them? TBH my subscription is ending in a few days and I need to download them ASAP.

2. I can try setting up a L3 CDM but if I don't have access to the page later, I don't think I can decrypt the files.

The video can be decrypted later if the pssh doesn't change, all depend in cloudfront. But to get the key you will need a subscription, so decrypting would no be possible in few days.
You can try getting your own L3 CDM, get one from the forum, or since as you said you are a "newbie" you could end up sharing account id password in private message.
To get your own L3 CDM follow : https://forum.videohelp.com/threads/408031-Dumping-Your-own-L3-CDM-with-Android-Studio
You can send a private message if you want to try the third option

The thing is, I have to download over 100s of videos and need keys for them. Even if someone is willing to help it will take time. I saved some videos with screen recording but it will take me a month to complete all videos, out of desperation I came here to test this method.

With a script it would not take that much time. Send me a pm if you want

Open your developer tools, in the Elements tab, look for the "player.vdocipher.com/v2" url (I'm 99% certain this is the case) and post it here, or send it to me in private.

aqzs is helping me with this.

I'm experiencing CDM blocking, I get : {"code":2042,"message":"Android system updates or update Chrome browser to play this video"}
I saw on others posts that "It is said that CDMs from emulators do not work on VdoCipher... It is worth debating."

I got my CDM from android emulator since I don't own an android device. My CDM(s) aren't leaked and works with every other services so it might be from the side of vdocipher who block android emulators (or old android version)

If someone knows how to deal with vdocipher..

yes you need proper CDM from real device

I don't own one since I don't have an android device.. I'm ready to give 10 CDM from android emulator for 1 from a real device but nobody would trade

@lazur9 have a subscription which expires on 6th, he would like to scrap the website before.. I'm able to make a script to scrap everything but i can't decrypt..

I have a custom script working for vdocipher (adapted from https://github.com/Diazole/vdocipher-dl) but the problem is my CDM

I have made some advancements but I would like to know : how to use a response like that ? :

Hmm; not sure - in my scripts I have this:

    if content_type.startswith('application/json') or content_type.startswith('text/plain'):
        match = re.search(r'"(CAIS.*?)"', license.content.decode('utf-8'))
        if match:
            license_content = match.group(1)

    # parse license challenge
    cdm.parse_license(session_id, license_content)

But that's for the case the response contains CAIS, I don't know what exactly CAUS is used for. (And to complete what I know: CAES is what the challenge data begins with.)
