download / decrypt protected video

[misiek]

Could anyone help me solve the problem of how to download a DRM-protected video?
There are a lot of posts on the forum and information on how to do it, unfortunately I can't understand it (sometimes the tips are too "general", for example :
use "such a tool" or "check this..."

so one by one: I can download the video using available tools, e.g. IDM, but the video and sound are unrecognizable / not showing in a player ( VLC )
if I run the command , tips from : https://forum.videohelp.com/threads/401172-Everyone-can-help-me-fix-error-on-mp4decrypt#post2709674
(I don't remember where and how I got this key, there were so many threads ... maybe F12 dev tools / inspect ? )

mp4decrypt.exe --key 1:v8vxqWHOeBivVOjEFF6EBhWadY1nmmOQ0hZGEBxR0FI=

the video is now visible but is "blurred" (see attachment)

I already know how to download the manifest.mpd file (attached as txt - error during uplad ),
what do I need to do next to download the video file and decode it correctly to be able to watch it?
maybe there is already post/page that explains in detail step by step: what is needed (tool and keys/codes etc.)
(recording the screen is very troublesome, thank you in advance for any tips/hints)

how should I use them in the next step?

[iamghost]

you got the wrong key
video URL?

[Imai]

try this PSSH:

AAAATXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAC0IARIQv66MxoRmrqsKjPRDt6SwCBoNY3lmcm93eXBvbHNhdCIIgJ4AAAAAAAA=

[misiek]

thank you for reply ,
so we have "another brick in the wall", ( we are one step further )
by the way, I have the question why we chose this entry of PSSH , there are more similar in mpd file
Is there a rule that we should always take entries that .... with... after... ? ( in in this case it is the second entry in the order) see piture
[Attachment 75759 - Click to enlarge],
and now the most important question:
what should I do now in the next step, and Is there anything else that we need to have, to decode the video?

[iamghost]

https://cdrm-project.com/
https://keysdb.net/
http://108.181.133.95:8080/
or wks-keys


[Attachment 75760 - Click to enlarge]


add pssh, license URL, and header

[imr_saleh]

use this pssh

AAAATXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAC0IARIQv66MxoRmrqsKjPRDt6SwCBoNY3lmcm93eXBvbHNhdCIIgJ4AAAAAAAA=

[misiek]

Well, now I have a question, why this entry PSSH ?
(this one is third in order in mpd file ), what is the difference between what imr_saleh suggests and what recommended earlier Imai
( different track / bitrate ? )
Ok , I will try with keysdb / cdrm ( we can read a lot about this on this forum )
but I did not find a precise explanation of how to use it and where to read the necessary entries,
e.g. I'm not sure if the License url in my case is ? [ https://b2c-www.redefine.pl/rpc/drm/ ]
If not , please provide info where can I read it.

my experience not that good but I know the basics.

Usually PSSH is short and you can see the end of it.

Next thing you need to do is search for the license URL so you can send the request
try search for (lic, license, wv, widevine, drm)

[Attachment 75763 - Click to enlarge]
once you find use one of this:

keysDB is a widevine
so use widevine pssh

[misiek]

Wow,
getting closer to the finale (it's getting more and more exciting)
but what was I doing wrong?
In the Headers field I pasted a very long entry from the website (dev tools, DRM , right click , copy as cURL, then convert it on the website https://curlconverter.com/#, as I understand it, we leave it as it is - > right ?
only :

accept: "*/*"
content-length: "316"
Connection: keep-alive

unfortunately it still throws an error
Error 400: 400: UnicodeDecodeError
maybe it has to do with the regional settings of the computer/browser-chrome (Poland)

However, you managed to download 5 sets of keys, so now the last (I hope ) question
how to use them / which one? / all ?

wrong keys, use with cached key they store keys with wrong license URL

[Attachment 75769 - Click to enlarge]

you can see different lic url with same keys you post

Update :
If I did everything correctly, then... I get this error

[Attachment 75765 - Click to enlarge]

use yaml
removed import requests and header =
like this

{
'authority': 'licensing.bitmovin.com',
'accept': '*/*',
'accept-language': 'en-GB,en-US;q=0.9,en;q=0.8',
'content-type': 'text/plain;charset=UTF-8',
}

[imr_saleh]

iv'e used this site: http://108.181.133.95:8080/
However none of these keys work, perhaps an incompatible license url

in devtools search for widevine, license, proxy, auth, token
you need to find the correct license url

Wow !!!!
Im very impressed
thank you very much, so it works ...
Can I ask you for "technical details" ( I need to prepare questions )

[misiek]

Update:
----------
Unfortunately, the solution provided by iamghost ( thanks ) was made using a special tool that cannot be used on a "mass scale"
I need to get the entire season of the series, about 150 episodes, therefore I need to understand "technicals" and do it using available tools
(cdrm-poject ) and get the decryption key
Because I am a beginner, so let's summarize it
I will present the current situation (please correct if something is wrong )
=============================================

I cannot provide a direct link to the video because it requires logging in, and the video is not available outside Poland,
but we have address of mafifest file (mpd)

https://ipla-e3-17.pluscdn.pl/p/vm2dash/8d/8d939608a7a7715a7a23564094570af54f192dba/manifest.mpd

filling the form ( cdrm-project )


[Attachment 75779 - Click to enlarge]

1) PSSH , getting from mpd file

[Attachment 75780 - Click to enlarge]
2) License URL , was it read correctly? (I've seen different opinions on this forum, so I want to make sure again)

https://b2c-www.redefine.pl/rpc/drm/

[Attachment 75781 - Click to enlarge]

3) Header
- > here I have the biggest problem, how to fill / what format
(conversion via https://curlconverter.com/ or http://yaml-online-parser.appspot.com/ ?)
and most importantly, where to get it ?
iamghost told that "I need right-click / copy as CURL .. etc ( picture )

[Attachment 75782 - Click to enlarge]

additional problem: which entry should I use? (there are different entries )
additionally, someone suggests using YAML, but there is an error there.. ( picture )

[Attachment 75783 - Click to enlarge]
additionally, if we try to generate a request on cdrm-project, we get an error ( picture )
I noticed that : (colon) is not accepted

[Attachment 75784 - Click to enlarge]

so how to do it to get key:

bfae8cc68466aeab0a8cf443b7a4b008:4ffa1edad4234f9a0da55a358d76479d

the first part 'bfae...008' is available in the mpd file )

Thanks,

use StreamFab check PM

[iamghost]

use StreamFab check PM

you can use streamfab, i have been check to see if it work,

yeah they do.


[Attachment 75786 - Click to enlarge]

[misiek]

OK. I will,
I will let you know if it works satisfactorily - thanks

[misiek]

( update )
Hi,
it works (with some limitations), e.g. downloading transfer ( max 12 MB/s )
and the inability to select an audio track (I can only download the lowest 64 kb/s (just for the needs of this series),
however, if someone told me the secret of how to fill out the form for the decode key (in especially the "Header" field)
using the cdrm-project website, it would be very nice ,
I know that the topic has been discussed hundreds of times on this forum, but unfortunately I have not found a comprehensive answer on how to do it
(maybe I was looking in the wrong place )

Thank you all for your help and tips

[labamba]

@iamghost @Silv3r is my understanding correct that streamfab should work on sites that require login? I'd like to download movie from app.filmbox.com. this site requires logining in. i downloaded streamfab, went to the web page, entered credentials, started playing movie and nothing gets detected in streamfab. should it be? I have mtd file for the movie and pssh. not sure what to do next. someone in another thread advised to look for "proxy". I have one but it points to "https://widevine-dash.ezdrm.com/proxy?pX=003389" and nothing is there ("HTTP Get Method Not Supported").

License server requests are always POST
