  joubert linked to an article outlining the specs that make up FaceTime. The same article is also linked in an answer on the SO page you linked to yourself. The pieces used in FaceTime are all listed there. I'm sure Apple will release some docs on how to tie them all together for FaceTime compat, but that will take time. Be patient. Till then here are links to the various specs: h.264: http://www.itu.int/rec/T-REC-H.264-200305-S http://www.itu.int/rec/T-REC-H.264-200305-S aac: http://www.arm.com/files/pdf/PRD10-GENC-001288-4-0.pdf http://www.arm.com/files/pdf/PRD10-GENC-001288-4-0.pdf sip: http://tools.ietf.org/html/rfc3261 http://tools.ietf.org/html/rfc3261 turn: http://tools.ietf.org/html/rfc5766 http://tools.ietf.org/html/rfc5766 rtp: http://tools.ietf.org/html/rfc3550 http://tools.ietf.org/html/rfc3550 srtp: http://tools.ietf.org/html/rfc3711 http://tools.ietf.org/html/rfc3711
