I Think im almost there

MPD
License URL

I have used EME logger for the PSSH ;

The length should be OK, a similar streaming platform (actually almost same company) uses the same system.

But the result is 5 Keys to decrypt
None of them work.

Also tried from MP4DUMP and the INIT mp4
That PSSH gives the same keys for this video

I think the result for this platform should be one key so either the PSSH or the License URL is incorrect
I cannot find any more POSTS to licensing URLs so this could be correct

Can someone give me a last push ? Perhaps the PSSH is wrong ?

Thank you

Thank you

shouldn't you use all 5 ?

mp4decrypt --key 1 --key 2 --key 3 --key 4 --key 5

Hmm I have tried that but it did not seem to work in my XstreamCli program
Turns out, works when i use mp4decrypt

Glad I god the key part right though

SO, yes thank you for the right direction

You are decrypting the video and audio separately right ?

And then merging to 2 decrypted parts to make the complete output file ?

Correct!

Last time someone got 5 keys and coudn't decrypt, most likely means that the keys are for the lower resolutions of the videos and you need L1 or other tricks for 720p and 1080p.
He got these keys

you need to check if the kids match the video kid

211ee9e4-24c8-4cb8-a58b-e209846b888b
this is the KID for the 1920x1080 version

in the MPD there's this

346p 2df24eb4-b806-43aa-8f6b-17908327ea76
416p d3764689-3e25-400f-a785-176e57acfde5
554p 7bbd2d48-b156-4522-85ef-5e1a3ee95a0a

692p 18df605c-bb8b-497a-86b3-bcffe60f93e6
1038p 211ee9e4-24c8-4cb8-a58b-e209846b888b

audio 1e61abb3-5339-4651-add1-e6fa0d2c9022

basically,, you dont have the keys for 692p and 1038p and you need L1 for those probably

In your MPD you have 6 KIDs
Compare them with the keys you got.

Ah yes, that helps me understand some more
If i generate the keys (5) it will decrypt 1080P video and the seperate audio track so im happy
