Help build gst-launch commands

[rbattu]

I guess the gdkpixbufoverlay is for the images only , I was able to set a
logo using this plugin as below.

gst-launch-1.0 -v tcpclientsrc host=192.168.0.102 port=5000 ! gdpdepay !
rtph264depay ! avdec_h264 ! videoconvert ! gdkpixbufoverlay
location=gstreamer-logo.svg offset-x=20 offset-y=20 ! autovideosink
sync=false

I too was struggling to put a time with clockoverlay, I enabled debug level3
and see the below errors, Any help is appreciated

gst-launch-1.0 -v --gst-debug=3 tcpclientsrc host=192.168.0.102 port=5000 !
gdpdepay ! rtph264depay ! avdec_h264 ! videoconvert ! gdkpixbufoverlay
location=gstreamer-logo.svg offset-x=20 offset-y=20  ! clockoverlay
halignment=1 valignment=2 time-format="%H:%M:%S" ! xvimagesink
