Why does UDPSink multiplex all the streams from the same port together?

[debruyn]

Good day,

I am currently developing a system that has multiple UDPSinks that sends to
the same port( Due to project restrictions). I am curious to know why
UDPSink multiplex all the streams from the same port together? I would think
that once a source has made a connection with a sink that It won't connect
to another senders address. I am doing this in c++ 11, but for debugging
these are my pipelines:

Two UDP hosts:
gst-launch-1.0 rtspsrc
location=rtsp://10.15.1.15:554//Streaming/Channels/101 user-id=admin
user-pw=admin123  ! udpsink host=10.15.1.139 port=5555
gst-launch-1.0 rtspsrc
location=rtsp://10.15.1.16:554//Streaming/Channels/101 user-id=admin
user-pw=admin123  ! udpsink host=10.15.1.139 port=5555

One UDP Client:
gst-launch-1.0 udpsrc port=5555 caps="application/x-rtp" name=UDP1 !
rtpjitterbuffer ! rtph264depay ! avdec_h264 ! theoraenc ! oggmux !
shout2send ip=10.15.1.139 port=8000 password=hackme mount=/test.ogg

When viewing test.ogg i notice that both streams are multplexed together,
thus the streams flicker between each other.
Any explination would be appreciated
