[Udpcast] Udp-sender take 3

Sorry, was on vacation when you answered...  Setting the family fixed the bind problem.

Using async mode and a --max-bitrate I can get it to run if I assign two different IPs to --mcast-rdv-address and --mcast-data-address.

I'm now working on the getting the rate governor to work. 

It appears that udp-sender  gets to the broadcasting control message and stops even in async mode..

Command is:

udp-sender -f filename -- async --fec 8x8 --mcast-rdv-address --mcast-data-address -g ipe.so:ip=,port 1024

Did you supply an ip=xxx and a port=xxx value to --rategovernor?

Such as
 --rate-governor ipe.so:ip=,port=4000

If that doesn't help, try adding the following line before the bind call in ipe.c (line 218):

  me->recv.sin_family = AF_INET;

Currently, UDPCast only supports IPv4
