how to get source host/port from udpsink
Locked
 
|
Is there anyway to get the source host/port from udpsink? I need to receive data on a udp port process it and send a response back to the original sender. I don't know the source host/port when the pipeline is created, so I can't set the destination host/port on the udpsrc until after I receive the first packet and retrieve the source host/port.

I would think the source host would be a property of a UDP packet and
not a listening UDP socket :) On Mon, Apr 19, 2010 at 6:34 PM, Attila RS <[hidden email]> wrote: > Is there anyway to get the source host/port from udpsink?

Well typically when you receive from a socket the host binding or sockaddr is separate from the actual received buffer. It does look like udpsrc is using GstNetBuffer instead of GstBuffer and the source addr/port is is added to the buffer. The down stream element should be able to cast the received buffer as a GstNetBuffer and extract the source addr/port.
