Multiple Streams via UDP While Limiting Bandwidth

My goal is to send two video streams from one computer to another and limit
the bandwidth being used as much as possible. I have no problem doing this
in one pipeline if I just send each source to a different port. However, I
figured it would be better to mux the streams together when transmitting and
demux when receiving. I have tried using mpegtsmux and tsdemux, but I can't
find how to split the streams apart on the receiving end.
-Here is the transmitting pipeline:
gst.parse_launch('mpegtsmux name="muxer" ! udpsink host=' + self.homeIP + '
port=1234 v4l2src device=/dev/video' + str(self.cam) + ' ! video/x-raw-yuv,
framerate=' + str(self.fps) + '/1, width=640, height=480 ! x264enc pass=qual
quantizer=20 tune=zerolatency ! muxer. v4l2src device=/dev/video' +
str(self.cam + 1) + ' ! video/x-raw-yuv, framerate=' + str(self.fps) + '/1,
width=640, height=480 ! x264enc pass=qual quantizer=20 tune=zerolatency !
And here is a receiving pipeline that receives the video from the first
gst.parse_launch('udpsrc port=1234 caps="video/mpegts,
systemstream=(boolean)true, packetsize=(int)188" ! tsdemux ! ffdec_h264 !
I need to figure out how I can access both streams. Or is streaming to
separate ports fine?
