Udpsink doesn't send anything

[José Luis Segura Lucas]

Good morning from Spain!

Today I was trying to send a raw video over the network using udpsink -> udpsrc connection.

On the receiver side, I ran this pipleine:

$ gst-launch-0.10 udpsrc ! filesink location="/tmp/file"

If I look at my listening ports with netstat, I saw the UDP port 4951 (as expected).

When I run (on my computer or on any other computer on my network) the "sender":

$ gst-launch-0.10 videotestsrc ! udpsink host=my_network_ip

Nothing happens. I use Wireshark to look at the network traffic generated on the server side and the client, but nothing is sent/received.

I tried with the example seen on http://www.gstreamer.net/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-udpsrc.html (using only audio instead video), but I get nothing too :-(

Can anybody help me?

Thanks in advance

The maximum udp packet size is 65535 bytes. Video frames are usually
much bigger than that and can't be sent over the network with udp like
that. You need to split the video packets with RTP or make them smaller
by compressing them.
