AW: dynamic videomixing

[Bernhard Graaf]

Hi Sérgio,

 

Thanks for answering. I’m very happy for your first answer (in my mind there
was a very complex construction if not :-))

I will try the second and third answer (should reboot to development system,
so it takes a wile).

 

Bernhard

Hi Bernhard, 

 

I've tested the pipeline below and it works so the answer to your initial
question is, yes you can have only one sink pad in the video mixer

gst-launch-1.0 -ev v4l2src ! videomixer ! xvimagesink

 

Regarding the second question. 

gst_pad_link()
<http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/Gst
Pad.html#gst-pad-link>  returns the reason why the link failed, and it is
normally quite descriptive as you can see on 

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstP
ad.html#GstPadLinkReturn . Try to see what it is returning in your case.

 

Also have you tried to test your pipeline in gst-launch with the video
mixer?

 

Sérgio
