matroska is not suitable for streaming. it is intended that you can
seek in file when you open it. much better option is using RTP or
MPEG-TS. so try replace matroskamux/demux with mpegtsmux and
tsdemux.<br>

<div>Hi,<br>
</div>
Just still stuck how I can forward the matroskamux to
tcpserversink on its own, any advise here? How to make it
stream in stead of saving it to a file? (once I get there I
will use tee to do both)<br>
</div>
Thanks,<br>

<div>Hi,<br>
</div>
I've been experimenting with
gstreamer for a while now and
got quite far for my level of
experience :) <br>
</div>
So now I can capture video and
sound muxed together from my
C920 to a file!<br>
</div>
<br>
gst-launch-1.0 v4l2src
device=/dev/video1 !
video/x-h264,width=1280,height=720,framerate=30/1
! h264parse ! \<br>
muxout. \<br>
pulsesrc
device="alsa_input.usb-046d_HD_Pro_Webcam_C920_F1894590-02-C920.analog-stereo"
\<br>
! queue ! audioconvert ! voaacenc
bitrate=65536 ! \<br>
muxout. \<br>
matroskamux name=muxout
streamable=true ! \<br>
filesink location=muxed-long.mp4<br>
<br>
</div>
As a next step I would like to also
stream the muxed audio+video
directly to tcpserversink. <br>
</div>
<div>Any tips how to forward the mux
to tcp? (and still capture)<br>
</div>
<div><br>
