Streaming audio and video RTP

[William Johnston]

You can only specify ports on element names. Try this:

gst-launch-1.0 -e \
         uridecodebin uri="file:///home/fedora/starwars.mov" \
         ! qtdemux name=demux  demux.audio_0 \
         ! queue \
         ! audioconvert \
         ! opusenc bandwidth=superwideband bitrate-type=vbr \
         ! rtpopuspay  \
         ! rtprtxqueue max-size-time=2000 max-size-packets=0 \
         ! udpsink host=www.playbacktc.com <http://www.playbacktc.com> 
port=5052 \
         demux.video_0 \
         ! queue \
         ! videorate ! video/x-raw, framerate=30000/1001 \
         ! videoconvert \
         ! x264enc tune=zerolatency speed-preset=1 dct8x8=true 
quantizer=17 pass=qual \
         ! rtph264pay \
         ! rtprtxqueue max-size-time=2000 max-size-packets=0 \
         ! rtpbin name=rb rb.send_rtp_sink_0 \
         ! udpsink host=www.playbacktc.com <http://www.playbacktc.com> 
port=5054 \
