License Url dmax.de

[DLH007]

Hello,

i was able to learn myself which tools i need to download videos and get the relevant informations to decrypt videos. My first try with success was joyn.de, but i fail with https://dmax.de/. Im trying to get https://dmax.de/sendungen/helden-der-landwirtschaft, the first episode.

I already have video/audio, the pssh and license url. Im trying to get the keys with cdrm-project, but the license url is special.

URL: https://discovery-eur.conax.cloud/widevine/license
PSSH: AAAAYXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAEEIARIQUs BsehxxQoCbpD8dxkKnShoFQ29uYXgiJDAwMDAwM2U5LWM1OTUt MzRiYS0yNTQ1LWVlZDMwZTMxZWI0ZQ==


But they use a special header request, i dont understand. Without the right request, i get:

Error 500: {"status":"UNGRANTED_REQUEST","code":500,"errorCode":6001,"message":"Internal error"}

header:

OPTIONS /widevine/license HTTP/2

How to put this correct in cdrm?

Thanks

[lomero]

from lic url copy auth data and paste on headers

key

cdrm-project does not work because isn't in your country
so, add proxy or use python and your own cdm

cdrm:

Thanks both of you, but i do something wrong. I get the same key as iamghost, but my video doesnt play.

I decrypt and use

ffmpeg.exe -i video_dec.mp4 -i audio_dec.mp4 -c copy final.mp4

but ffmpeg say

[mov,mp4,m4a,3gp,3g2,mj2 @ 00000254df04ea00] Incorrect number of samples in encryption info
video_dec.mp4: Invalid data found when processing input
[mov,mp4,m4a,3gp,3g2,mj2 @ 00000254df26ff00] Incorrect number of samples in encryption info
audio_dec.mp4: Invalid data found when processing input

Im wondering, should it possible to play the decrypted files on their own? I can play them, but video without picture and audio without sound.

For the first Episode, use key found by Lomero

b40681515c11459893a26fc1d6aa1e06:83879c2fb33e05eaf7ce5b3e8d43860f

[DLH007]

Oh thanks, i overlooked the key from lomero. But why does @iamghost have a different key?

Video works now, now i have to learn how to get the keys myself.

[cedric8528]

I suppose that iamghost had found a key for another episode

[iamghost]

I suppose that iamghost had found a key for another episode

my key is for Episode 1, other key is for episode 9 i check

[cedric8528]

Sorry iamghost....wrong PSSH for me (from EP9)

So this is the good key

Try with N_m3u8DL-RE

N_m3u8DL-RE --key 52c06c7a1c7142809ba43f1dc642a74a:555c0929482f40ef16d04db175096a16 "https://dplaydk-prod-vod.akamaized.net/f174c974-1d7d-4bda-816c-a9ab77aa8460/dash_widevinePlayready_fmp4/hdntl=exp=1685980655~acl=/f174c974-1d7d-4bda-816c-a9ab77aa8460/dash_widevinePlayready_fmp4/*~data=hdntl~hmac=9cb5bd9f3387338ef95ef30a7f3c4848ac6e4665e8554ae65d2433a3a41fc22e/master.mpd" -M format=mp4

Put mp4decrypt and ffmpeg in the same folder

I miss the like button for posts .

Thank you very much.

@cedric, this information in code box a very useful

[DLH007]

Now i have own CDM, using l3.py and input pssh and lic url, give error

unable to parse license - check protobufs

Maybe wrong header? Any advice?

device_client_id_blob and device_private_key are from android studio pixel 6.

[iamghost]

no need all in header.py
look highlight on the right side,copy this in header.py (left side)

[DLH007]

Still the same error .
Maybe my CDM-Files are blacklisted?

[DLH007]

Its working now, have used wrong combination from pssh and preauthorization.

I like the forum, people are very helpful

[sk8ordi3]

all pages available this button "Alle Videos zur Sendung"
this makes all the video links visible and makes it easier to automate the process

Hello sk8ordi3,

i dont know how to use this script. I am a complete newbie at python.

[sk8ordi3]

Hello sk8ordi3,

i dont know how to use this script. I am a complete newbie at python.

copy the whole code into a text editor
save it as e.g.
something.py

then put it in the folder where you have the l3.py file

to run: (double click)
something.py

you will also need these exe's in the same folder:
N_m3u8DL-RE.exe
ffmpeg.exe
mp4decrypt.exe

[DLH007]

Wow

what a great script, thats nice and easy

Thank you very much
