Forcing a specific demux based on a filename's extension can be done in
src/input/demux.c . It doesn't seem possible to change the jpeg demux
code (modules/demux/image.c) easily to automatically detect such files
since they just look like regular jpeg files with some extra headers
according to http://developer.mobotix.com/docs/mxpeg_frame.html .
