As you can see I have used

gst-launch-1.0 rtspsrc location=rtsp://10.1.97.12/media/video1 latency=2 ! rtph264depay ! h264parse ! queue ! omxh264dec ! nvvidconv ! xvimagesink
and I have success for this step.

also:

ffmpeg -thread_queue_size 512-i "rtsp://10.1.97.12/media/video1 -vcodec rawvideo -vf scale=1280:960 -f v4l2 threads 0 -pix_fmt yuyv422 /dev/video0
