I’ve never seen the fourcc JJPG before. A web and usenet search turned up nothing. Do you know the program/application that produced the file? (it can be something like a CAD program or a webcam)
Also you can try making copies of the file and attempting to change the fourcc to MJPG. I wonder if it could be some proprietary flavor of motion-jpeg. (other examples include Ljpg for lead motion-jpeg, CJPG for creative, GJPG for grandtech, IJPG for intergraph, mJPG (a version that came out before the MJPG standard was finalized), and WJPG (Winbond?))
