[vlc] Having trouble defining a Universal Plug'n'Play interface

[Adam Stein]

Running vlc v2.0.10 on  a Fedora 19 system.  Tried to see a media server
on my home network (Universal Media Server to be specific) using the
Local Network/Universal Plug'n'Play choice in the Playlist.  Whey I try,
I get the following:

upnp services discovery: Initializing libupnp on '(null)' interface
upnp services discovery error: Initialization failed: UPNP_E_SOCKET_BIND
main services discovery error: no suitable services discovery module

A quick look at the code (upnp.cpp) that puts out this error message
shows that it's in an #ifdef block for IPV6.  I also see that I need to
specify the interface (it looks like each time I run vlc) using the
--miface option.

My ifconfig shows two interfaces, em1 and lo.  Thought lo might work
since UMS is running on the same machine.  Any way, neither work.  Still
get that initialization failed message (but at least it shows the
interface I specified in the 'Initializing libupnp' message).  All my
devices use IPV4.  What should I set the miface interface to to get vlc
to see media servers on my home network?
