I have the RB5 Dev Kit, which comes with 2 cameras. A large wide angle camera and a smaller camera.
I was able to access the large camera with
gst-launch-1.0 -v -e qtiqmmfsrc name=qmmf qmmf.video_1 ! video/x-h264,format=NV12,width=1920,height=1080,framerate=30/1 ! h264parse config-interval=-1 ! mpegtsmux name=muxer ! queue ! tcpserversink host=0.0.0.0 port=8888
Thanks in advance.
