I want my app to mirror the display of my iPad 2 to my Mac.
I have published the _airplay._tcp service and am listening on the port 7100. The app shows in the AirPlay menu and the Mirroring option is also there. Video and audio streaming work perfectly.
But I don't know how to decode the FairPlay encryption (POST /fp-setup) to support AirPlay mirroring. I have taken reference from http://www.aorensoftware.com/blog/2011/08/20/exploring-airplay-mirroring-internals/. If anyone has any idea on how to do that, please tell me.
Check out AirServer -> they've already done this and it works flawlessly (almost)..
They are using AES encryption, -- partially right. But very long code in fp-setup handshaking,(First FP-SETUP, Second FP-SETUP, fpaeskey encryption) and also the real decryption part is Apple's customized module.
