Downloading from CDA.PL

[PepeForEver]

I will write what actions I performed:
1) First, I copied the folder with all the contents called "pywidevine" from the WKS-KEY folder to the folder "C:\Users\UserName\AppData\Local\Programs\Python\P ython312\Lib\site-packages\
2) From the android_generic folder I copied 2 files named: device_private_key , and device_client_id_blob
3) Then I wanted to create a WVD file by running on the command line:
pywidevine create-device -k "C:\Users\UserName\AppData\Local\Programs\Python\P ython312\Lib\site-packages\pywidevine\device_private_key" -c "C:\Users\UserName\AppData\Local\Programs\ Python\Python312\Lib\site-packages\pywidevine\device_client_id_blob" -t "ANDROID" -l 3 -o "C:\Users\UserName\AppData\Local\Programs\Python\P ython312\Lib\site-packages\WVD"
4) I received the message:
"Traceback (most recent call last):
File "<frozen runpy>", line 198, in _run_module_as_main
File "<frozen runpy>", line 88, in _run_code
File "C:\Users\UserName\AppData\Local\Programs\Python\P ython312\Scripts\pywidevine.exe\__main__.py", line 4, in <module>
ModuleNotFoundError: No module named 'pywidevine.main'
5) Please help for which I thank you in advance.

Yeah, you're doing it entirely wrong. You don't use an existing pywidevine from I dunno where, you install it fresh using pip install.

https://pypi.org/project/pywidevine/

Delete the old one from where you copied and install new.

Dump your own CDM and try with those. All the steps are detailed on the stickies.

Thank you for help, unfortunately, I have another problem and questions,
In your code "
WVD_FILE = "device_wvd_file.wvd" "should I give the path or just the file name? Should I change the name of this file to e.g. "google google_android_sdk_built_for_x86_v4.1.0-android_xxxxxxxx_xxxx_l3.wvd" i.e. the one that was generated? Because unfortunately I have problems again :/ thanks for answer.
Where should the .wvd file be placed?

[PepeForEver]

With a lot of help from 2nHxWW6GkN1l916N3ayz8HQoi I did some important things, but I managed to get something that is close to the final solution, i.e. I got PSSH, License URL, Manifest, link to .MPD file ,but unfortunately I get an error:
Traceback (most recent call last):
File "C:\Users\UserName\Downloads\DRM-xxxxx\DRM\CDA.py", line 141, in <module>

place the .wvd file in the same directory as the python script, rename it to device.wvd and in the script put 'devide.wvd' : device = Device.load(r"device.wvd")

If you named your CDM 'device.wvd' and placed it in the python code as 'device.wvd', then from the directory where you run the script you have to place the CDM.

You should have something like that :
device.wvd, cda.py in the same folder, open a cmd in this folder and run : python cda.py

The download command can be used without a VPN to avoid wasting data. The site uses Cloudflare protection but that can be bypassed by generating a cf_clearance cookie using an automated browser. The non-DRM content can be easily downloaded by looking at the network requests for a mp4 file.

What browser did you use to extract the mpd links?

In most browsers I have an mpd vp9 link - where I download files in webp format - which is useless.

If the script is not working for a specific case, provide the URL you are attempting. I have no idea what you're asking me.

Many thanks !!! to 2nHxWW6GkN1l916N3ayz8HQoi for his kind help! , brilliant script that works perfectly.
I have a question, is it possible to use the website https://cdrm-project.com/ , having PSSH, license URL, headers, custom data obtaining keys without your own CDM ( Free DRM content from CDA.PL ) ?

[2nHxWW6GkN1l916N3ayz8HQoi]

is it possible to use the website https://cdrm-project.com/ , having PSSH, license URL, headers, custom data obtaining keys without your own CDM?

Yes, it is possible. But out of principle, I won't add "magical" external APIs that make the job easier for the end-user. There will be more points where stuff could break unexpectedly and also people won't even care how to dump a CDM anymore, so I won't do that. If anyone else wants to modify this script to add that, then feel free to do it.

[PepeForEver]

Thanks for the detailed explanations!

MPD H264 can be obtained in the browser: Iridium browser, Microsoft Edge (Windows) / Mozilla Firefox (Linux). In other cases, the video loads from mpd webp.

Movies : https://www.cda.pl/video/18723067d0/vfilm

MPD H264 : https://vcze190.cda.pl/18723067/18723067.mpd - obtained from Microsoft edge
MPD WEBP (vp9) : https://vcze190.cda.pl/18723067vp9/18723067.mpd - obtained from Google chrome

Supposedly the same movie, but different MPD - depending on the browser or operating system.

Webp is more difficult to decrypt, connect and recreate.

[2nHxWW6GkN1l916N3ayz8HQoi]

MPD H264 can be obtained in the browser: Iridium browser, Microsoft Edge (Windows) / Mozilla Firefox (Linux). In other cases, the video loads from mpd webp.

If you take a look at the script you'll notice this line

browser = spw.firefox.launch(headless=True)

So I'm using firefox.

[peabody70]

How about this movie?

Open network requests. Filter for mp4. Select 720p quality. Take last request and copy the URL in a new tab. Right click save as video. It doesn't even use DRM.

Edit: I checked yt-dlp also. It works directly with that as well
