Unfortunately it's generally difficult to tell.  One thing you can do 
is look at the original JPEG header (i.e., before you strip it away 
for streaming), and compare it to the synthetic JPEG header that 
"JPEGVideoRTPSource" would prepend to each incoming frame (see the 
function "createJPEGHeader()" in "liveMedia/JPEGVideoRTPSource.cpp").

Also, if you have a RTSP server already working with your JPEG 
source, you can run "openRTSP -m" on it, to write each incoming frame 
(each preprended with a synthetic JPEG header) to a file.  You can 
then try viewing these files in an image browser.
