<title>MPEG-4 systems</title>

Abstract

We briefly describe the process for creating an MP4 file and introduce the software tools used for the creation. Then, we describe the architecture of an MP4 player - Flavor Player - that implements the MPEG-4 Systems specification. The Flavor Player implements 2-D composition and depth ordering of objects, object animation, user interaction, MPEG-J, IPMP framework, and MP4 file support. Additionally, we describe a simplified version of the Flavor Player - Mild Flavor - that only implements the Object Descriptor Profile. Unlike the Flavor Player, Mild Flavor is also used to create and edit MP4 files in addition to playback.
