Wowza™ media server software can be run in a mode where Datagram (UDP unicast and multicast) ports can be shared between incoming streams. This enables multiple SDP files to share video or audio channels, a single SDP file to be loaded by several application instances, or a single MPEG-TS stream to be loaded and different PIDs be referenced using query parameters.
To turn on Datagram port sharing, edit [install-dir]/conf/Server.xml and set <RTP>/<DatagramPortSharing> to true. Datagram port sharing is off by default.
