You first need to download the video and audio somehow, then use mp4decrypt.

You don't need two keys, only one (the one that is NOT KID).

Check the track of the video/audio with mediainfo and just use

mp4decrypt.exe --key 1:blablabla --show-progress video.mp4 video_dec.mp4

the 1 in 1:blabla should be changed with the track number and blabla with key of course.

ID is what you need, usually 1, as it is.

this worked

mp4decrypt.exe --key 1:8bf589882c53ec6d71d5efa506bd4696 --show-progress video.mp4 video_dec.mp4

What software do you extract MPD file on this video? I use ffmpeg to extract but don't work...

[lomero]

see notaghost post: your error is --key 1:.........
correct syntax is:

mp4decrypt --key <id>:<k> --show-progress encrypted.mp4 <input> <output>

try and post here your comment

Still error...

[lomero]

oh my god.
input.mp4 is the real name of your video? my string above is example only....
write on your command the REAL name of your video, extension also. same thing for output extension.
if u have lollypot.ts (input) final output is: blablabla.ts

It doesn't work because you need to find a modified youtube-dl that evades DRM.
His thing worked because he probably has a modified version of youtube-dl that you won't find on this site.

yt-dlp should work

- download yt-dlp.exe

- list video and audio streams:

yt-dlp -F --allow-unplayable-formats "https://manifest.prod.boltdns.net/manifest/v1/dash/live-baseurl/bccenc/5219833342001/2258ecb1-d01d-4616-a2bb-477c7b200b2b/2s/manifest.mpd?fastly_token=NjA3OTgzNTVfMDViNmE5ZmY4ODBlODkzYjgxYTFjMDg2YWVkODcwNDI2NmFiY2I2NGQxNDc4OWViM2FhNGM4NmIyYmZhZTliYw%3D%3D"

rename the downloaded file to 'video.mp4'

- download best audio:

yt-dlp -f bestaudio --allow-unplayable-formats "https://manifest.prod.boltdns.net/manifest/v1/dash/live-baseurl/bccenc/5219833342001/2258ecb1-d01d-4616-a2bb-477c7b200b2b/2s/manifest.mpd?fastly_token=NjA3OTgzNTVfMDViNmE5ZmY4ODBlODkzYjgxYTFjMDg2YWVkODcwNDI2NmFiY2I2NGQxNDc4OWViM2FhNGM4NmIyYmZhZTliYw%3D%3D"

rename the downloaded file to 'audio.m4a'

- decrypt video:

mp4decrypt --key ab549bb0526b43c39659cb5dcd94cce1:8bf589882c53ec6d71d5efa506bd4696 video.mp4 video_decrypted.mp4

- decrypt audio:

Interesting. Can anyone explain why this works, since yt-dlp is not supposed to go around DRM?
So, this --allow-unplayable-formats is basically a switch to evade DRM?

[lomero]

yes. is a workaround.

[yuusakuri]

Could you please tell me how to get the key?

[lomero]

wedevine decryptor extension. old version of chrome (not actual version) or other chromium browser (better).
then console tab after play vids.

[yuusakuri]

Thank you!
I installed the extension on Chromium and succeeded in getting the key.

[lomero]

yes work.
also we have other browser chromium based like slimget, or vivaldi, or brave. all very nice. and all similar but different.
only latest chrome version don't show key (wedevine ext is blocked bowser side).

[yuusakuri]

The following message is displayed on the console.

Can't verify license request signature; either the platform is wrong or the key has changed!

Only a few days ago I was able to get the key.
The browser is Chromium and Brave installed from Chocolatey. The OS is Windows 10 2004.

You first need to download the video and audio somehow, then use mp4decrypt.

You don't need two keys, only one (the one that is NOT KID).

Check the track of the video/audio with mediainfo and just use

mp4decrypt.exe --key 1:blablabla --show-progress video.mp4 video_dec.mp4

the 1 in 1:blabla should be changed with the track number and blabla with key of course.

Please help me it only say "ERROR: invalid argument for --key option" whats wrong, and can you help me? i use this code

mp4decrypt.exe --key 839c239f-e07b-41ab-aa1d-1b9207cf0061 --key 839c239f-e07b-41ab-aa1d-1b9207cf0061 --key 839c239f-e07b-41ab-aa1d-1b9207cf0061 Video.mp4 Videodecrypt.mp4

There are no dashes in KID:KEY.
This is a dash -
You have that.
Also, that thing you have with dashes is probably KID only. You are missing the KEY part from KID:KEY.
Read the sticky threads.
