Hi everyone,

I'm newbie on gstreamer. I'm using nxp I.MX8 and i need your helps.

latency=0 name=src src. ! rtph264depay ! queue ! h264parse ! vpudec ! 
videoconvert ! videoscale ! waylandsink window-width=352 window-height=288"

This command runs succesfully in terminal. But i want to write C code of 
this command and i tried this. Attached code in this mail. The problem 
of me when i run the code that attached, i have an error like showed below.

Error message:

"Pipeline state changed from NULL to READY:
Pipeline state changed from READY to PAUSED:
