corrupted stream after decrypting

[antik85]

I can't figure out what am I doing wrong with this. I already got these keys:

0100ac7ed511383d2bd98cd4b7f3ca9b:be68c413f0e147f4cf8a50fd7c10b82f

I use this command:

I selected to download only the 720p video, all audios and all subtitles. I'm getting these errors:

If you check it with mediainfo, they apparently are unencrypted, but still they are unplayable. At this point I'm not sure if they are corrupted, still encrypted, or what. I have also tried to download them with yt-dlp, decrypt them with mp4decrypt, but I had no luck either. I don't see where's my error, hope you can help me please to see where's my mistake, I want to learn. Thanks.

where are the keys?

I don't understand... where or how did you get those KID's? I could only get the 4 indicated KID-KEY with WKS-KEYS.

Discussing paid videos is already against the rules.
For @Frieren's reply, s/he is talking about those missing keys, because we can't find these key ids in what you gave us.
And as for your question, try decrypting them manually or do not mux them beforehand, i.e. to download the video & audio, then decrypt them manually.

The KID:KEYS I provided have been obtained with WKS-KEYS, also the same results using the CDM-Project extension:

I have inspected now the mpd and I found those KID's that Frieren said, anyway they don't show up in either WKS-KEYS or The CDM-project extension, so... I don't know how to continue.

Well I finally could solve it by myself . I'll leave it here in case anyone needs it.

The problem is that for some reason (that I still don't understand), either when you use EME Logger or the CDM-Project extension, you get a wrong PSSH, which takes you to get a wrong KID-KEY pair, resulting in an unplayable video after decrypting.

The solution is to inspect the mpd and find there the correct PSSH for the desired resolution, in my case, 720p. Take that new PSSH, use it in WKS-KEYS, and you'll get the real working keys:
