help with decrypting flv live stream
VLC is somehow able to play the video, but it is partially corrupted, as shown above.

When attempting to play the stream on this website (https://bilibili.github.io/flv.js/demo/), I receive information regarding the decryption keys, as shown in the image below

By providing the `key_id` to the license URL, I am able to retrieve the decryption key:

https://jdrm-license-cf.@@@.com/api/v1/jdrm/th/GetEncryptKey?authKey=eyJhb..-pGokwDig5mMqz-E&key_id=16d994bf4f4111f0aac200163e323f7c

"message": "success",
"request_id": "",
"code": 1,
"data": {
"key_id": "16d994bf4f4111f0aac200163e323f7c",
"key": "8820975b219c432abe197a99cf395bed",
"enc_algo": "v1"
}
}

this python code should generate fresh URI from API (you may need middle east IP)
