Hey everyone,
I'm quite new to the whole topic of downloading DRM content, but it's super exciting.
I found a movie, which is publicly accessibly that I would love to download:
https://www.freeform.com/movies-and-specials/659acbfb-17b8-4048-9644-2f891192093d
Here's what I did so far:
I tried to obtain the PSSH through EME, but that didn't work out. Instead I found the link to the MPD-manifest in the Network Developer Tab (filter for "mpd").
In this Manifest I find 24 Widevine pssh entries, however its the same 3 ones 8 times....
In my first attempt I downloaded the video & audio via yt-dlp.
Then, I used https://cdrm-project.com/ to generate the key by using the PSSH and License URL from the MPD-File.
Finally, I used mp4decrypt to decrypt the downloaded video and audio files.
Unfortunately, that didn't work out - the files are still not decrypted...
After playing around for some time, I realized something:
Each time, I download the manifest file again, it contains new PSSH entries, which are not the same as before...
After this observation I tried a new attempt. Now I used --dump-pages for yt-dlp to get access to the manifest file that yt-dlp uses for the file downloads.
That way, I should be able to access the exact PSSH that matches the downloaded video and audio...
With this new files and PSSH entries, I generated new keys and tried mp4decrypt.... but it didn't work out again.![]()
Now, I'm quite lost how to proceed here.
Can anyone help me out and point me what to do next?

Use 'Modified_eme_logger.js' and the extension of TamperMonkey for the browser

Where do I get the modified file?
I only that one https://greasyfork.org/en/scripts/373903-eme-logger
Or is that what you mean? -
Okay, so I tried to EME logger (https://greasyfork.org/en/scripts/373903-eme-logger) again and it still shows nothing in the console.
With other websites it works great however...
But apart from the EME logger issue, how do I work with those always changing pssh files?
How do I determine the correct key to decrypt the files?Last edited by curious2025; 6th May 2025 at 06:55.

The PSSH usually can also be read out from the encrypted file - it's part of the MOOV atom. Search this forum for scripts that can do it for you.

You're on the right track. You've done the hard work in getting the 3 keys. I use N_m3u8DL-RE which allows the keys to be put into the command line.
Code:N_m3u8DL-RE -mt --key eedb2b70154043f499692d31da9a1d4c:5432458bc32e976691f04b679154beb5 --key 59ec6cb9a2cb4bd68808cc323a332c40:6f4219223771eb4929e564ec3c16b8a5 --key 5b18e90dba4d42ccb83e608586e7ab42:08e87cb2e57d0ca972ada956114c811e "https://content-dtci.uplynk.com/ext/3605f191611c4f129693c83bd79c35b8/240dee26ce1b4d8fb559329ea66a14ad.mpd?cqs=qyboHVwhf25WFn6XLipnOPTaTbv3eDWJWy_uCHZAvtCtvikg19VFItWGM8eFUp9DpD6FWcrQfnDCTUuh4T4R4vMcqrlUNFSrEgFSf8TBcA6HxVsnIOSL2TXKElQ2UZs77GYFNFMZlxHzJmyU2V-kQiiP7lRsdtgvnUup2eN3wULqnJZ8YS5LKSia3S4_k35OmSv7kTOjehQIqLkYHjQ27V4aL4DbiGejTyZwlx2OBbFZOf5y_he-dksaa-rDnryInqMYD14QZGUJzn6HiYBar70KchCoecGGHB5vo76DhMGl6qFKoOc-rjp7fxxMfA7-KoWp3rWzN34skMNQ5b_gyP7Jq_1Tk6jru1GHBM4qfZOl-Our8tgfdeYlRhZKVWk3sZ-rnaTf3XJ8e8gzApEI1APOwQpvVdYEZrhZRwrgtTicev6MRHp4rrb0weCKZhGqPjphIgaEMYITOo2P9PaOlf3XP4Ty7Qq5DUrXwP6tva4SPQOBTXJ-AWLIgrbzRBwNY1ouUSPLeN1fQwHDBy5NEyX7T1iZ3v-6QFZAxqeJ9cj5u3fVKQo_6OVyVqkV9VM91twXkd0RYZEP3AappLVJGQ==&kid=1613528939cf4bb5915d23c702c3d1cf" -M format=mp4
