Description

The rtp muxer takes multiple RTP streams having the same clock-rate and muxes into a single stream with a single SSRC.

gst-launch-1.0 rtpmux name=mux ! udpsink host=127.0.0.1 port=8888        \
             alsasrc ! alawenc ! rtppcmapay !                        \
             application/x-rtp, payload=8, rate=8000 ! mux.sink_0    \
             audiotestsrc is-live=1 !                                \
             mulawenc ! rtppcmupay !                                 \
             application/x-rtp, payload=0, rate=8000 ! mux.sink_1
In this example, an audio stream is captured from ALSA and another is generated, both are encoded into different payload types and muxed together so they can be sent on the same port.
