How to remove DRM after download file

[euphonic]

hello everyone.
I am totally newbie to this topic and it is causing me a huge problem.
Namely, from the website: cda.pl I want to download content protected by drm.
I download them using Internet Download Manager 6.41
But each file plays correctly only the first few seconds and the picture is still green.
The file has the correct weight and length.

Example link: https://www.cda.pl/video/262796134/vfilm

how can i decrypt it, i don't know anything about batch files or commands at all

I'm surprised IDM let you download anything at all. It typically halts immediately if the content is DRM protected. Either way, in order to decrypt, you need to retrieve decryption keys. How to do that is all over this forum. Spend some time reading and you'll get it. For the actual decryption part, you need a program like mp4decrypt. And yes, it's run through the command line. Don't be afraid of it, learn it. It's not hard.

For your example link specifically, if you already have the file saved to your hdd, you'd simply run a command like this:

mp4decrypt --key 61653262333039343331393831383733:36303336616430343734353534623934 nameofencryptedvideofile.mp4 nameofdecryptedvideofile.mp4

If none of this makes any sense at all to you, please spend some time reading through the forum. Everything you need to know is in here.

How can I get this key?
is it the same one for each movie from this server or for this especially movie in variable option quality (720,1080, etc)



BTW: my downloaded movie has been decrypted but have bad quality and no audio - source file has the same low bitrate and no audio

[stabbedbybrick]

Please read the sticky threads up top on how to get and work with keys.

The key will be different for each movie, but will work for all quality profiles and audio. I grabbed the 1080p version to check and it worked fine. The reason your file has bad quality/no audio is probably because you used IDM. It's a great downloader for simple videos, but for DRM media you need other tools like yt-dlp or N_m3u8DL-RE.

yes I read it, but without tutorial with screenshot is to complicated for me

[stabbedbybrick]

There are videos posted around the forum for other services that you could watch and apply to this one. But you can't escape the fact that you'll need to do some studying if you want to learn.

I understand it all. It's just foreign to me and I get discouraged quickly when something doesn't work out for me.
Certainly the method to create a CDM is out for me.
Unfortunately, I don't know much about the command line either, which also takes me back a hundred light years

Where to look:

pssh
KID
key

The stickies are the most simple way to explain how to get what you need. Unfortunatly is't not a simple process - it's not meant to be simple... thats the whole point of the services using DRM.

If those methods are too complicated for you then you are unlikely to be able to acheive what you want on your own. Your only remaining options are using 3rd party software if they support the service you require (anystream/Streamfab etc.) or torrents etc.

The process is actually simple: Using an Android emulator (a virtual Android device) to communicate with the lic server (WKS is the emulator)

What makes the process difficult: Site designs. Sometimes it becomes impossible to find the needed-things under Dev Tools.

if we talking about this sticky topic: https://forum.videohelp.com/threads/408031-Dumping-Your-own-L3-CDM-with-Android-Studio
no one mented about KID and key just two files device_client_id_blob and device_private_key or is this what I'm looking for

[T33V33]

device_client_id_blob and device_private_key <- this is your CDM... That thread is all about dumping you CDM. The other stickies then explain what to do next

[euphonic]

and where is KID and key?

EDT...

I'm downloading Android Studio now

I'll try

kid inside on mpd

key you get with python and some other stuff ... not easy to do (for beginners)

I can handle it with .mpd and passh and KID

I need to know now how to get keys from python and what? other stuff?

Now that you are aware of it, you can work on yourself to correct it.

I might be wrong, but it seams like Getwvkeys is not an option anymore (other people have also reported problems with accessing the Discord group as if it just magically faded from planet earth).

They stopped accepting new members a few weeks back.

The following link redirects you to a post from [ss]vegeta in a different thread on this forum. It includes a video on Drive that may (or may not) be helpful. I hope I am allowed to post links to different threads on this forum. If not pls tell me and I will edit this post ASAP.

This is slightly off topic, but I do wonder, why did you (and many other's) recommend Getwvkeys rather than CDRM-Project? Is this only due to preference or is there more to it. I did hear that CDRM-Project fails (gives invalid keys) more often than Getwvkeys, but is there more?

Along with PSSH and license, you need the custom token as a single header for this service. You'll find it as one of the headers of the license.

It should look like this:

ok, then download again your video with N_m3u8DL-RE

put ffmpeg and mp4decrypt on same folder with N_m3u8DL-RE

N_m3u8DL-RE -M format=mp4 --key 61653262333039343331393831383733:36303336616430343734353534623934 "https://vcze174.cda.pl/12076884vp9/12076884.mpd"

Thank You for code, but my codes for N_m3u8DL-RE and yt-dlp
are workin fine NOW!!
Now we have other errors - Streamfab

encoding with 'idna' codec failed (UnicodeError: label empty or too long) error
