Problems with cdrm-project.com

[corvo4791]

Hello, everyone.

I need to download a video from a website just to upload it on YouTube as a private video and generate automatic subtitles. I need to do it because I'm Italian and the video would be more understandable for me with subtitles. I downloaded the video but the image is totally black and there's no audio. I thought that's because of Digital rights management (DRM) and I'm trying to learn how to unlock this content.

I followed the procedure shown in this video (use FIREFOX to open it): https://web.archive.org/web/20220301190239/https://streamable.com/umoszy

but https://cdrm-project.com/ always returns me this error: Error 400: Custom Data is Required
There's no mention of this error in the FAQ and the cdrm-project Discord server is dead.

These are my values:

I feel that I'm next to the solution but I missed something.
I also read this thread: https://forum.videohelp.com/threads/409260-Need-help-with-lic-drmtoday-com-license-server but I failed anyway.

Any Help?

Thanks.

Url?

[corvo4791]

Url?

URL of the video you mean?

This is the MPD: https://video.watchcorridor.com/2204f46a-2145-4045-9dfd-d1aa22874301/dash/68031d39-7d2...d6b93df0dc.mpd
and this is the mp4: https://video.watchcorridor.com/2204f46a-2145-4045-9dfd-d1aa22874301/dash/68031d39-7d2...df0dc_3840.mp4

but I wrote it as: https://kms.watchcorridor.com/v1/widevine

why did you change the license url?
that extra query parameter is most likely the custom data thats required.

from decoding that base64 data - the cd value expired a bit over 2hours ago - Wednesday, April 26, 2023 9:29:49 AM GMT
try refreshing the page to get a new license url and use the full url this time

again another same post ....

I used both full and changed url and both returns different error messages.

I did the procedure again and I get a generic Error 500:

I put here all the data. Please, check yourself. Thanks for your help.

Your PSSH is wrong, that's why you're getting errors.

I followed the video step by step, what did I wrong?
Can you help me to find the right PSSH?

edit: I also opened the .MPD file with Notepad and the PSSH is clearly written inside it and it is exactly the same I already posted here. Why you say it's wrong?

edit 2:
I also tried to obtain the PSSH using KID. I've found it in the .MPD file and it's value is: 34d45f3d-5844-46ba-bb49-2c4478b1f4d2
I used this tool https://tools.axinom.com/generators/PsshBox and I used as SYSTEM ID the code I've found in the name of the MP4 file I downloaded with YTDLP = 68031d39-7d2e-4164-992d-70d6b93df0dc
The PSSH obtained is different than the first one but, when I use it, it returns this error: PSSH ERROR unable to parse init data

New PSSH = AAAAO3Bzc2gAAAAAaAMdOX0uQWSZLXDWuT3w3AAAABvfh3jl/d37nzjj7jptr5tvj37ZzjjvxvV/h3Y=

Nice work, you almost got it. System ID is EDEF8BA9-79D6-4ACE-A3C8-27DCD51D21ED, just select it in the dropdown menu. Then put Key ID in the other box and Generate.

Thanks, everyone, for the help, really, but I'm here to learn a method. I need to know how to obtain stuff and not just obtain it.

How did you obtain that SYSTEM ID ?
Which dropdown menu are you talking about?
Which KEY ID are you talking about?

Don't talk as I already know what's this stuff. I'm totally new to this.

Thanks.

On https://tools.axinom.com/generators/PsshBox, if you click inside the System ID box there is a dropdown menu. Select the one for Widevine.

In the Key ID box below, you paste the KID from the MPD. Then press Generate and you've got a valid PSSH.

Now do us all a favor and read through the forum and educate yourself. There's only so much spoon feeding people can do.

With this final hint, I accomplished my task. Thank you so much.
