FaceTime is by far the most popular video calling system available for mobile terminals, Apple Lossless Audio CODEC (ALAC), releasing it for its devices in 2010 along with iPhone 4. If you were ever interested in finding out how this system was created, well an engineer from the Apple Lossless Audio CODEC (ALAC), revealed in the trial between Samsung si Apple Lossless Audio CODEC (ALAC), the details behind the creation process of this system. The base code of FaceTime was created in 2007 when he created a prototype that allowed making voice calls between a Mac and an iPhone.
Garcia and four other engineers spent essentially all of their time on the project, and various other teams worked on pieces related to the technology. Apple's core audio team did the audio backend, dealing with the microphone and speaker, Garcia said. The video codec team was also involved, as was the application team, "which draws pretty buttons and things like that," he said.
Continuing the development process, in 2008 Apple engineers managed to make the first video calls between a Mac and an iPhone, but FaceTime would evolve differently. To launch Game Center in 2009, the Apple company asked the engineers to develop an audio chat system for users and the code designed for this system would be the basis of FaceTime. Using the code written for the Game Center function, FaceTime would eventually have several tens of thousands of lines of code, but Steve Jobs was not satisfied with the initial prototypes.
Jobs wanted a system that would work without problems and without a complicated configuration method, so Apple engineers had to redo a good part of the system before it was available in its current form. Additional details about the process you will find here, plus information about Jobs' requirements for securing FaceTime.
