Yang Jiwen, Hello 

you can use dynudpsink instead of udpsink. and then you can g_object_set socket in the element.

Hi,
Thanks for your suggestion, I added SO_REUSEADDR and bind.. something in function gst_multiudpsink_init_send yesterday and it works. I think it's better to add a source port property for it in future. To set the sender's source port freely in udpsink is quite useful especially in some P2P applications, for NAT stuff. 

Regards,
Yang

May be you can pass a file descriptor with the 'fd' property.

To manage RTP you will probably have to manage RTCP, so two contigous 
port numbers. Using external fd throught udpsink you are able to do
that.

Regards.
