Motion JPEG Chunk File Format

This document describes the motion JPEG chunk file format. The utility vid2mjpgc can be used to convert from Parallax .vid files to MJPEG chunk files. The utility avi2mjpgc can be used to convert from J300 .avi files to MJPEG chunk files. The utility movieToVid can be used to convert Parallax J_Movie files to .vid files which can then be used by the MJPEG File object or made into a MJPEG chunk file. The filename extension conventionally used for MJPEG chunk files is ".mjpgc".

The MJPEG chunk file contains 5 chunks:

  • Media Independent Header Chunk
  • MJPEG Header Chunk
  • Frame Time Table Chunk
  • Frame Offset Table Chunk
  • Data Segment Chunk
