Sure, just create a test.sdp file as follows:

------------ test.sdp ---------
v=0
o=- 22714557 1 IN IP4 127.0.0.1
s=123123
t=0 0
m=audio 1234 RTP/AVP 100
c=IN IP4 192.168.1.34
a=rtcp:9 IN IP4 0.0.0.0
a=sendonly
a=rtcp-mux
a=rtcp-rsize
a=rtpmap:100 opus/48000/2
-------------------------------

and run:

ffmpeg -loglevel debug -protocol_whitelist file,udp,rtp -async 1 -i
test.sdp output.wav


After some seconds the process will exit.
