More than one video publisher in a multicast enabled netgroup

Question

I wonder what will happen if more than one members of
a netgroup publish video and audio with the same stream name at the same time; and all the members of the netgroup play the very same stream. the video will come in one by one or whatever? By the way, the the netgroup enables multicast
                groupSpecifier.multicastEnabled = true;
                groupSpecifier.postingEnabled = true;
                groupSpecifier.serverChannelEnabled = true;
The scenario is quite common in a video conference room.
Thanks in advance

if more than one stream is published to a group with the same name, then the data for all of the streams will flow through the group.  however, each subscriber to that named stream will select/latch onto just one of them.  there's no way to control which one each subscriber selects, though.  if they're all active, then the first one from which a subscriber receives any data wins.  if the stream onto which a subscriber has latched goes idle, then the subscriber will un-latch and selection will again be up-for-grabs to the first of the streams from which data is received.
each time a subscriber latches onto a new/different stream, you'll get a NetStream.MulticastStream.Reset NetStatusEvent.NET_STATUS event.  you won't get one of those if the subscriber un-latches but then reselects the same stream.
if you're concerned with rogue publishers in a group, same name or not, consider adding a publish password to the group specification.
