two RTP streams + SDP
address must be multicast.

$ ./ffmpeg  -f dshow    -i video="eEver USB Video Device":audio="麥克風 (eEver USB Audio Device)"  -c:v copy -r 30 -an -f rtp   rtp://236.0.1.10:2000   -vn -c:a pcm_alaw  -f rtp  rtp://236.0.1.10:2001 >aa.sdp

spontaneous playback

 ./ffplay.exe -protocol_whitelist file,udp,rtsp,rtp  -i aa.sdp
