Abstract
Overview
ISO/IEC 14496-14:2020 defines the MP4 file format as a specific instance of the ISO Base Media File format (ISO/IEC 14496-12). This third-edition (2020) standard specifies how MPEG‑4 audio‑visual content and associated metadata are stored, identified and organized in MP4 container files. It covers the mapping of elementary streams, object descriptors, track management, synchronization, and additional MP4-specific boxes and fields used for interchange, editing and streaming workflows.
