<DIV>Hi,all:</DIV>
<DIV> I have a problem about groupsock when I run live lib on my embeded linux system.</DIV>
<DIV> The program work fine until, recently, I run PPPoE on my embeded linux. The program print :</DIV>
<DIV> </DIV>
<DIV> "Unable to determine our source address: This computer has an invalid IP address : 0x0"</DIV>
<DIV> </DIV>
<DIV> Then, I found the print coming from GroupsockHelper.cpp and Groupsock.cpp. I don't know what's wrong with the program because there's no problem when I run Groupsock without PPPoE. And the system can also work with running PPPoE and unicast, but the printing ---- able to determine our source address: This computer has an invalid IP address : 0x0" ---- is still exist.</DIV>
<DIV> </DIV>
<DIV> When I run PPPoE and Groupsock, the video transport program shut down and print:</DIV>
<DIV> </DIV>
<DIV> "00:00:11 Groupsock(10:239.255.42.42,1234,7): failed to join group : setsockopt( IP_ADDR_MEMBERSHIP) error : No such device.</DIV>
<DIV> </DIV>
<DIV> Could you give me some suggestions?</DIV>
