gstreamer command Issue.

Thanks Yair!
Below is the command working fine

# gst-launch-1.0 pylonsrc ! "video/x-raw, format=GRAY8, width=1280,
height=720" ! identity silent=0 ! videoconvert ! autovideosink

My goal is to run this command inside rtsp media server test-launch binary
as I want to stream it on a webpage. But when I run this I am getting the
following error while playing it in vlc player.

#  * ./test-launch "( gst-launch-1.0 pylonsrc ! video/x-raw, format=GRAY8,
width=1280, height=720 ! identity silent=0 ! videoconvert ! identity
silent=0 ! x264enc ! identity silent=0 ! rtph264pay name=pay0 pt=96 )"*

stream ready at rtsp://127.0.0.1:8554/test

-------- When I try to play the stream (rtsp://127.0.0.1:8554/test) in vlc
Below error happens ---------

x264 [error]: baseline profile doesn't support 4:4:4

x264 [error]: baseline profile doesn't support 4:4:4

Thanks,
Issac
