Hikvision- What is the encryption used for RTSP Stream?

[radgid]

Hi,

I am able to capture the stream from NVR. The stream is encrypted (platform encryption key is set) The stream data are saved into the file (video1.mpeg).
I am not sure what is HikVision using for encryption of the RTSP stream.
I tried to decrypt the stream data with aes256 using my encryption key, but decrypted content is not mpeg or anything recognized by VLC player - so it seems I did not use proper decryption.
The tool I used for decryption is openssl:
openssl enc -d -aes-256-ecb -in video1.mpeg -out video-dec256.mpeg -nosalt -md sha256 -k MYSECUREKEY -nopad

Did someone tried decrypting the RTSP stream from HikVision already ?

Cheers,

I'm not aware of a solution to this.
You can disable the encryption.
