WV Keys Don't Work

[origamimagor]

Hello,

There is a video I want to download, respectively decrypt. I am able to download the video, I am able to get PSSH, license and WV keys, but I don't know why, these keys don't work and video is still unplayable.

The link for the video is here, but it is important to note, that you will need Czech VPN to get access. Then you have to wait when the commercial ends. And the MPD is time limited, it will expires soon after the launch:

Please, can you help me, what I am doing wrong?

Thank you very much in advance.

Could not reproduce. Key 26a0524b869a512fb81f3efd916c173e is used for decryption of both video and audio. The others are irrelevant.

To check whether it's the right kid:key, just open up the MPD and find all the KIDs.

there is no KID in mpd.

if there's no KID in MPD, there will be PSSH which can be used to derive KID
