dynamic videomixing

[Sérgio Agostinho]

Paste the console output of your pipeline

gst-launch-1.0 -v tcpclientsrc host='192.168.1.4' port=12000 ! queue2 !
decodebin name=decoder decoder. ! queue ! audioconvert ! audioresample !
pulsesink   decoder. !  queue ! videoconvert ! xvimagesink

and also with the videomixer

gst-launch-1.0 -v tcpclientsrc host='192.168.1.4' port=12000 ! queue2 !
decodebin name=decoder decoder. ! queue ! audioconvert ! audioresample !
pulsesink   decoder. !  queue ! videoconvert ! videomixer ! xvimagesink
