[MPlayer-users] how to set interface for rtsp?

[sean darcy]

I'm on a laptop connected by wireless - wlan0, trying to play a stream:

mplayer -rtsp-destination 10.10.11.170
  rtsp://server:1935/plp/mp4:Play-2004-300k.mp4

I'm getting a bunch of:

Unable to determine our source address: This computer has an invalid IP 
address: 0x0
Unable to determine our source address: This computer has an invalid IP 
address: 0x0
Unable to determine our source address: This computer has an invalid IP 
address: 0x0

and it doesn't play. FWIW, it does play using vlc as the client. I think 
one problem is that mplayer is not binding to wlan0, at least for the 
udp stream.

It negotiates with the rtsp server, but does not get/see the stream itself:
