How to decrypt IQIYI client bbts

[forget]

This is the 4k link on the client side. The TS format was not encrypted for the first 6 minutes, and then the BBTS format was encrypted. I want to know what encryption method this is and which decryption method is used

To save you time, there is no public bbts decryptor for IQIYI; only a few have it.

But if you want to watch it offline, there's a manual method by nilaoda here: https://github.com/nilaoda/Blog/discussions/79

这是PC客户端帧绮映画 4K需要抓包，浏览器不提供此画质（The translation is not accurate. I am writing in Chinese and I don't know if you can understand it）

Thank you, got it
I am not proficient in Python, which makes it difficult for me. I have the latest version of QSV decryption to MP4 converter, but I also hope to manually decrypt it myself
