How to forward muxed video-audio to tcp sink

[Bart Koppe]

Today there's no problem. Hmm, any tips to make it more stable? I did add
aacparse to be sure..

gst-launch-1.0 v4l2src device=/dev/video1 !
video/x-h264,width=1280,height=720,framerate=30/1 ! h264parse ! \
muxout. \
pulsesrc device="alsa_input.pci-0000_00_1b.0.analog-stereo" \
! queue ! audioconvert ! voaacenc bitrate=65536 ! aacparse ! \
muxout. \
mpegtsmux name=muxout ! queue ! tcpserversink host=192.168.2.13 port=5000

Thanks!
