CSI YUV Capture,nvvidconv latency

Thanks ShaneCCC,DaneLLL
I have two questions??

1-In the YUV method, I have almost a delay frame(30 to 50 millisec), If I use this sample, will the delay problem be solved?

2-How can I connect a multimedia sample to gstreamer library?
I want to transfer the video frame to the network and I need a udpserver and rtspserver of Gstreamer SDK!!
Is there an example of the connection between the two ??
