[FFmpeg-user] Multicast UDP Port Issues

I have a multicast stream containing six programs coming into my office over
one single udp port. 

I am able to map the programs, and run multiple instances of ffmpeg using
the same port without a port binding error by using the option ?reuse=1.

Now, my problem is that when I push these streams back out to our broadcast
server, only one stream can be watched.  It seems to be the last ffmpeg
instance that I run is the one that is viewable.  The other streams just
dont show up.

Here is my code...

/root/bin/ffmpeg -loglevel 0 -re -i
-map 0:p:2 -async 2 -acodec libfdk_aac -vcodec libx264 -threads 2 -f flv
rtmp:// </dev/null> /dev/null 2>&1 &

What do i do to correct this issue?
