The method is so simple:

1- List all of the audio and video formats in a MPD:

I suppose you've already downloaded yt-dlp... In the folder of "yt-dlp.exe", go to File > Open Windows Powershell and enter the following command:

./yt-dlp --list-formats --allow-unplayable-formats http://www.xxxxblablabla.mpd (link of your mpd)


2- Download the audio/video stream you want, by entering its ID which is listed by yt-dlp.

For example, if you want stream 8, the command will be like this:

./yt-dlp -f 8 --allow-unplayable-formats http://www.xxxxblablabla.mpd


Audio files are always downloaded very slower than video files. Be patient.

when do you input the keys is it you use mp4decrypter.

[ridibunda]

when do you input the keys is it you use mp4decrypter.

Powershell command-line template:

./mp4decrypt --key KID:KEY InputFile OutputFile


Example for a video file:

./mp4decrypt --key f22422630a704379b08e7f6ad6b70801:69e2113cbb00435cb 21b79f6d9d2c6e1 encrypted.mp4 decrypted.mp4


Rename the mp4 video file you downloaded as "encrypted". Place "mp4decrypt.exe" and "encrypted.mp4" in the same folder. You'll get the decrypted file in the same folder.

For audios, file extensions are "m4a".

Don't thank me, I'm just a messenger

Thank to members like [ss]vegeta. I learned from them.

Hola, no sé si me pudieras ayudar, tengo el .mpd, pero al realizar estos pasos no consigo obtener las claves para descifrar el audio encriptado.
¿Existe alguna forma de obtener las claves partiendo de la dirección .MPD?
Al poner ./yt-dlp -f 8 --allow-unplayable-formats [url del MPD]
Me apararece:
[generic] stream: Requesting header
WARNING: [generic] Falling back on generic information extractor.
Alguien sabe como se soluciona o si tiene solución?

Muchísimas gracias por toda vuestra ayuda.

Use Google Translate please. Write in English.

Here's what Joseitos said:

Hi, I don't know if you could help me, I have the .mpd, but when I do these steps I can't get the keys to decrypt the encrypted audio.
Is there any way to get the keys from the .MPD address?
By putting ./yt-dlp -f 8 --allow-unplayable-formats [MPD url]
It appears to me:
[generic] stream: Requesting header
WARNING: [generic] Falling back on generic information extractor.
Does anyone know how to fix it or if there is a solution?
Thank you very much for all your help.

You can't get keys from MPD.

To get keys, you need PSSH, license URL and license request headers. And a working (not-revoked) CDM, and a Python script or a website like http://getwvkeys.cc

I wrote how to find PSSH.

You can find license URL and headers in "Developer Tools" section (in a browser, Edge/Firefox/Opera)

And... "./yt-dlp -f 8 --allow-unplayable-formats" is just a random example. In your case, stream IDs will be different.

Thanks for the reply @ridibunda

First of all, thank you for how well you clarify each of the steps.
I suppose it is not as simple as it seems, although everything has its trick.
I've managed to get the PSSH inside the MPD, but I can't find the license URL and license request headers; When I access Inspect on Network from Chrome, the audio and video file appears, but I can't find any license URL data in the Header and it doesn't find anything if I filter by widevine.

This is what appears to me:

This is what I can get, then in the other tabs like the Response tab I get some encrypted lines but I can't copy them, when copying and pasting it doesn't paste anything.
I don't know if I can get anything with these data or if I should rest from trying.

Hi can you help me downloading from drm site (i have the permission to download from them obviously )

Yes, of course I can.
Yes, of course you have the permission FROM THEM to download something that has DIGITAL RIGHTS MANAGEMENT because they decided to manage their digital rights by allowing YOU SPECIFICALLY to download.

[JustTheWayItIs]

Vegeta, I have a DRM encrypted .mp4 video file and .m4a audio file.

Would you be able to please help me on how to decrypt these so I can watch the episode?

Thanks so much.

[[ss]vegeta]

Would you be able to please help me on how to decrypt these so I can watch the episode?

We need to get to the source of where the video can be watched. We need to gather some data like license url, headers and PSSH.
Unless we do at least that, we can't get the keys.
Send me login credentials for that site.

[ridibunda]

@Joseitos

To find request headers, go to Developer Tools > Network... Search for values like "widevine" "drm" "license" "lic" "cenc"... (Cenc is for MUBI).

You will find more than one. Once you find 2-3 lines with the same name like "cenc", take the one with the longest content-length. You'll see all content length values. You will also see the license URL there.

License URL can also be seen in Developer Tools > Console (with EME Logger script)

If you cannot find anything, reload the video playback, try again.

If you find nothing again, then it means they are hidden in site-design, so you will have to use a proper Python script to reach them.

Hey, So i have the MPD file and from it i get the PSSH and the KID and i download the files thru N_m3u8DL CLI. After that, i try using mp4decrypt and when i do that and it finishes i play the video and it is just a blank screen.

Am I doing something wrong? I am fairly new with this so please bear with me.

[k2000]

You have the key decryption when you use mp4decrypt.
If you don't have the keys, it won't work. You need a cdm and WKS-KEYS or the NotAGhost site to get the keys.

[knageh]

Thanks! That worked!. How do i do that with audio, or is this with video only?

[k2000]

The keys obtained are for Video and Audio but it happens that some site has no DRM on audio.

[knageh]

thanks for that but i ran into what i think is a problem when i put the pssh in the website it gives me multiple keys. which one is the correct one?

[ElCap]

thanks for that but i ran into what i think is a problem when i put the pssh in the website it gives me multiple keys. which one is the correct one?

does the response look something like this? (with a different license server than you put in)

Cached PSSH
License:https://widevine-proxy.appspot.com/proxy
PSSH:<pssh>

Time:<time>

<key 1>
<key 2>
<key 3>

if so, untick the Cache box and try again

[knageh]

It looks like that but i am pretty sure I am doing something wrong because I don't change the license URL. I Leave it to be the default one. How do i get the proper License URL from the MPD?

[lomero]

no from mpd.
play video and search on network tab

[lakis112]

i also need some help if you can,i am trying to download from a provider in my country that also uses drm protection,through the directions i read from here i got the pssh and licence from .mpd and then i used http://getwvkeys.cc/ and got 5 keys,when i try decrypt with mp4decrypter i have a new video but it doesnt seem to be correct,i need some help on if i am gothering the correct information please.

[mahdisky]

http://getwvkeys.cc/ is it work for udemy?

[Mirai]

Thanks to the kind folks here I managed to download and decrypt a widevine protected video.
While I managed to decrypt both video/audio files, I'm still missing the subtitles, this is one of the lines I found in the mpd file

<Representation codecs="stpp" startWithSAP="1" mimeType="application/mp4" bandwidth="4096" id="4" />

I googled "sstp" and sure enough it's a subtitle codec, yet after downloading the mpd via yt-dlp it only gives me two file formats, mp4 and m4a, without any subtitles, not even embedded in the video.

Here's the code I used to download the mpd file:

yt-dlp --allow-unplayable-formats "mpd"

Any help would be appreciated.

Thanks for the quick reply. I'm getting ERROR: [generic] manifest: This video is DRM protected.

I already have the wv key, perhaps I can implement it into the command somehow to bypass this message?

[[ss]vegeta]

No, that's not the problem.
Just add

--allow-u

alon with the other commands.

I tried this before, and yes it worked but it wasn't the desired result. I expanded on the issue here, I felt the issue needed it's own thread.
