How to forward muxed video-audio to tcp sink

[Bart Koppe]

Hi,

At first I got tcpserversink working with mpegtsmux.

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 ! \
muxout. \
mpegtsmux name=muxout ! queue ! tcpserversink host=192.168.2.13 port=5000

client: cvlc tcp://192.168.2.13:5000

I played the stream (video+audio) for quite long. When I got back I wanted
to start including tee for hdd saving. But then I found out the audio
piping was not working anymore. Only if I use matroskamux (because i used
it earlier) and save to disk i get audio, but then only for a bit.  But
mpegtsmux with tcpservsink gicves no audio anymore.

I'm expecting some faulty syntax from me?

vlc says:
[0x7f3b08001d58] ts demux error: MPEG-4 descriptor not found

Thanks!
