I'm sorry but your suggestions didn't work:

>>> import pygst                                                      
>>> pygst.require("0.10")                                             
>>> import gst                                                        
>>> import gobject                                                    
>>> pipeline = gst.Pipeline("rtp-pipeline")                    
>>> source=gst.element_factory_make("udpsrc")
>>> source.set_property("port",2546)                   
>>> source.set_property("timeout",5000000)
>>> caps=gst.Caps("application/x-rtp, media=(string)video, payload=(int)121, clock-rate=(int)90000, encoding-name=(string)MP4V-ES, profile-level-id=(string)1")                                                                  
>>>depay=gst.element_factory_make("rtpmp4vdepay")                                 
>>>pay=gst.element_factory_make("rtpmp4vpay")
>>>destination=gst.element_factory_make("multiudpsink")
>>>destination.set_property("clients",'192.168.2.102:6000')
>>>pipeline.add(source,depay,pay,destination)
>>>gst.element_link_many(source,depay,pay,destination)              
True                                                                            
>>> pipeline.set_state(gst.STATE_PLAYING)
>>> pipeline.get_state()[1].value_name
'GST_STATE_PLAYING'
>>> for i in pipeline.elements():
...    if 'rtpmp4vpay' in str(i.get_name()):
...        pay=i                            
...
>>> pay
<__main__.GstRtpMP4VPay object (rtpmp4vpay0) at 0x1515d20>
>>> for j in pay.src_pads(): print str(j.get_property('caps'))
...
None
>>> for j in pay.src_pads(): print str(j.get_caps())
...
application/x-rtp, media=(string)video, payload=(int)[ 96, 127 ],
clock-rate=(int)[ 1, 2147483647 ], encoding-name=(string)MP4V-ES
>>> for j in pay.src_pads(): print str(j.get_negotiated_caps())
...
None


If I use the caps from gst-lauch to build the sdp I can see the video, so the
pipeline really works

thanks
Nicola
