The code works only with AP and STA but not with STA only

Thanks for the video stream app. However I find this:
When I set for clients "ns3::StaWifiMac", and for server "ns3::ApWifiMac", then only it works.
But it doesnot when I set all nodes as "ns3::StaWifiMac". I want to set client server in adhoc mode(MANET). What to do?
It gives me an output:
Frame list size: 0
