[Live-devel] Failed to join group: Invalid IP Address

[Ashfaque]

Thanks a lot Ross. I added route and it worked fine.. Now able to stream between platform to iPad.

But there is another issue we are facing after streaming is started, Wifi connection is getting disconnected after streaming for some 5 minutes duration (ping response fails).
We are doubting the application as the devices are able to ping for a long duration also(when streaming application is not started).

Console print (Not sure whether it will help).

Can you please provide some inputs on this.

/* Debug prints on connection lost on console */

  It shows following error messages:

  00:07:36 Groupsock(8: 232.202.29.84, 18888, 255): failed to join group: setsockopt(IP_ADD_MEMBERSHIP) error: No such device

It sounds like you don't have any multicast route set up on this device.  (The code uses multicast, initially, to figure out the system's own IP address.) 

Make sure that you have a route for 224.0.0.0/4 set up on your network interface.  Then the code should work.
