AW: AW: AW: Video streaming with one frame per 3 seconds

[Bernhard Graaf]

You should mux the audio also. In your pipeline you have only the videopart.

As I told you, I don't know anything about ksvideosrc and it sounds like
only video source.
Muxing of audio and video is something like:

gst-launch-1.0 videosrc ! videoconvert ! tsmux name=mux ! sinkelement
audiosrc ! audioconvert ! .mux

I don't see any audiosource in your pipeline. If ksvideosrc has also
audio-pads, it could be something like:

gst-launch-1.0 ksvideosrc name=src ! videoconvert ! tsmux name=mux !
tcpclientsink .src ! audioconvert ! .mux

If I use these pipelines(without muxing):

*gst-launch-1.0 ksvideosrc  ! videoconvert !
"video/x-raw,format=(string)I420,width=320,height=240,framerate=(fraction)25
/1"
! queue max-size-buffers=70 
! gdppay ! tcpclientsink port=7887

gst-launch-1.0 tcpserversrc port=7887 ! gdpdepay ! decodebin ! queue !
autovideosink*

then I get nice fps rate, so this works!

But I need video and audio muxing for my app, so how I can do this with nice
fps rate?
