Efficient File Structure for Real time 3GPP/MP4 Movie Capture
Video is typically captured in 3GPP/MP4 file format on personal devices like Cell-phones, Tablets, DSC, etc. These file formats link to audio and video units in the header, making header size variable to the actual duration of video capture. This paper explains these schemes along with newer scheme that places of header towards end of movie file eliminating limitation of capture duration or additional post-processing or complexity of multiple files. The proposed scheme is implemented in C5X DSP resulting simpler system with enhancement of 3GPP/MP4 movie multiplexor.
