Also tried running the following command (removed gst-launch-1.0)..with this parsing errors gone. but still not working.

$ GST_DEBUG=2 ./test-launch "( pylonsrc ! video/x-raw, format=GRAY8, width=1280, height=720 ! videoconvert ! x264enc ! rtph264pay name=pay0 pt=96 )"

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 )"

note, GRAY8 is not supported in x264 (or RTP in general)
so videoconvert will adapt it to another (RGBA), rtp/x264 compatible format.
this might bite you if you plan to manipulate the GRAY8, as GRAY8, upstream.

see
