You'll have to tell GStreamer a little more about the mjpeg stream by adding
a capsfilter that looks like:

souphttpsrc location=$uri !  "image/jpeg, framerate=$fps/1" ! jpegdec
! videorate ! sink

Obviously $fps is known outside of GStreamer and is probably already
part of the URI.
BTW, using multipartdemux after your http element could be a good idea.
