An application that concatenates 2 videos (mpeg4 format) into a single video 1 of the video will be "the main" and will be the longer video and the second one will be the "secondary" hence the shortest one,
The source of the 2 videos could be from either the iphone's camera or iphone's file system.
The user will decide in which segment of the "main" video the "secondary" video will be concatenated. For example he/she can decide in which frame of the "main" video the "secondary" video will be embedded....make sure the application PRESENTS the frames (not all of of them of course but one for every 3 seconds from which the user can select where his/hers secondary video will be embedded).
Needless to say an audio should also be concatenated.
The video composition will be based on iOS4's AV foundation.
Attached are 3 slides describing the main requirement of this project.
The project has 2 phases the first one is the application itself. (the UI and graphics doesn't matter) the second one is a delivery of the source code.
