 No, as long as you stay within GStreamer, the per-frame timestamps are used 
and the framerate doesn't really matter.  It's only when you mux it into a 
file again that the framerate is used.  Maybe you're storing it in an AVI 
file, that doesn't have per-frame timestamps so when you play it from the 
file it uses the 100fps value.

 You could fix the rtspsrc to extract the framerate from the SDP message...

 Regards,
 Arnout
