What's 3GP?
3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for use on 3G mobile phones but can also be played on some 2G and 4G phones. The 3GP file format is structurally based on the ISO base media file format defined in ISO/IEC 14496-12 - MPEG-4 Part 12. 3GP is a container format very similar to MPEG-4 Part 14 (MP4), designed to decrease storage and bandwidth requirements in order to accommodate mobile phones. It stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC or HE-AAC.
