Not really. [udpreceive~] is meant to receive from [udpsend~]. They send 
packets of audio samples along with the some parameters and a frame 
count. Unless your sender formats the data the same way, it just won't 
work. The thing to do would be send using a [udpsend~] in the Pi, or 
else find out what gstreamer is sending and write an external to decode 
that inside of Pd ;)
