No, you shouldn't do that, because the downstream object (usually a 
"MPEG4ESVideoRTPSink") assumes that data is fed to it one frame at a 
time.  (If you feed it more than one frame at a time, the resulting 
output RTP packets might not be compliant with the standard payload 
format, and might therefore end up being misinterpreted by a 
receiving client.)

A "MPEG4VideoStreamDiscreteFramer" should be fed exactly one MPEG-4 
video frame at a time.
