How to download from 3voor12 Vpro?

[elektro]

For instance this clip: https://3voor12.vpro.nl/speel~WO_VPRO_20067330~ellie-goulding-live-at-pinkpop-2023~.html

I managed to get the MPD. The license server seems this one:

https://npo-drm-gateway.samgcloud.nepworldwide.nl/authentication

What's missing are the 2 keys. Inside the MPD it seems it's this KID:

cd381d253f68b3ac8c94e0525faaba1d

The PSSH is more confusing and I don't get what's the correct version. So, how do I get the other key? I need a working N_m3u8DL-RE command and I also need to understand what's the exact method to get other similar clips from that site.

I got the following:

KID

CD381D25-3F68-B3AC-8C94-E0525FAABA1D

PSSH

AAAAOHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABgSEM04HSU/aLOsjJTgUl+quh1I49yVmwY=

KEY

cd381d253f68b3ac8c94e0525faaba1d:b33b844c9e6421652e83f06018b494ea

This worked for me:

N_m3u8DL-RE -mt --key cd381d253f68b3ac8c94e0525faaba1d:b33b844c9e6421652e83f06018b494ea "https://npo-nl-ams-p28-am3.cdn.streamgate.nl/eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE3Njg1MjY1OTEsInVyaSI6Ilwvdm9kXC9ucG9cL3VzcFwvVEVTVFwvbnBvcGx1c1wvZGFzaF9jZW5jXC9XT19WUFJPXzIwMDY3MzMwXC9XT19WUFJPXzIwMDY3MzMwX3YxNjg3NDUyNjU5LmlzbSIsInZpZXdlciI6InZpZXdlciIsInJpZCI6IjY1N2MxM2QifQ.oKZv_ACm9d55oqJd3oCi6wTMvcIldVNwxvKOnFlb5Mo/vod/npo/usp/TEST/npoplus/dash_cenc/WO_VPRO_20067330/WO_VPRO_20067330_v1687452659.ism/stream.mpd" -M format=mp4 -H 'accept: */*' -H 'accept-language: en-GB,en-US;q=0.9,en;q=0.8,el;q=0.7' -H 'cache-control: no-cache' -H 'origin: https://3voor12.vpro.nl' -H 'pragma: no-cache' -H 'priority: u=1, i' -H 'referer: https://3voor12.vpro.nl/' -H 'sec-ch-ua: "Google Chrome";v="143", "Chromium";v="143", "Not A(Brand";v="24"' -H 'sec-ch-ua-mobile: ?0' -H 'sec-ch-ua-platform: "macOS"' -H 'sec-fetch-dest: empty' -H 'sec-fetch-mode: cors' -H 'sec-fetch-site: cross-site' -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/143.0.0.0 Safari/537.36' --save-name "Ellie Goulding-Live at Pinkpop 2023"

Thanks, it worked. With that PSSH I could generate the keys using a CDM as well. Now, how did you get that specific PSSH? It seems obfuscated in the MPD file.

Sorry, mistake on my part!

No problem. But can you explain how did you get that specific PSSH value which is different than the ones from the MPD? Did you use a Base64 decrypter (if yes, which one?)

Looking at it, used an old script which generates a PSSH based off the KID. In saying that, did go back and used the PSSH in the MPD and that worked as well. In CDRM-Project you do need to be quick to get the PSSH copied across as well as the licence URL before the token expires or else you will get an error.

You can always extract the PSSH from the downloaded mp4 - https://forum.videohelp.com/threads/414431-Getting-the-pssh-data-from-a-encrypted-mp4
