Stream RTSP from h264 /dev/video src

[dor.forer]

I managed to fix it using:

How to send video stream over UDP network by RTP

$./test-launch "videotestsrc is-live=true ! video/x-raw, width=1920, height=1080, framerate=20/1 ! nvvidconv ! video/x-raw(memory:NVMM), width=1920, height=1080, framerate=20/1, format=UYVY8 ! omxh264enc insert-vui=true insert-sps-pps=1 ! video/x-h264, stream-format=byte-stream, alignment=au ! h264parse ! rtph264pay name=pay0 pt=96 ! " stream ready at rtsp://127.0.0.1:8554/test

But I need a guide on how to stream h264 src, and not a YUYV src like shown in the guide.
Thanks.
