From your posted image, you are filtering on the Network. Try Filter for init or maybe e+ on the Console while using the tampermonkey addon with eme logger javascrpt.

from urn:uuid and KID you can get pssh

from urn:uuid and KID you can get pssh

do you mean this one?

uuid?cb=540751a6-89de-4f9f-75ae-ed6db4f88221

default_KID="00000000-0000-0000-0000-000003211933"

Then what to do next~?

I setup tampermonkey and add eme logger javascrpt, then reload the video. The code I found is correct?

The way you provided is effective, but one problem is that my ch4 py can not caculate the code.
