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

------------ test.sdp ---------
o=- 22714557 1 IN IP4
t=0 0
m=audio 1234 RTP/AVP 100
c=IN IP4
a=rtcp:9 IN IP4
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.
