The current version of pycriusm has some unknown problems. I'll try to fix it when free.

Do you know how to get a key using Iridium-SR ?

I am looking for information about packetIds.json and StarRail.proto.

reprod case: decoding CS_Chap03_Act150_f.usm will yield corrupted video (audio is ok).

Interestingly short looping clips like CS_ChapLoop03_Act0080_f.usm works fine.

yeah, because it's not encrypted.
