Gst-launch-1.0 rtspsrc pipeline

i have a successful pipeline:

gst-launch-1.0 playbin uri=rtsp://

and a pipeline on failure:

gst-launch-1.0 rtspsrc location=rtsp://
! rtph264depay ! h264parse ! nvv4l2decoder
! ‘video/x-raw(memory:NVMM), format=(string)I420’
! nvvidconv
! ‘video/x-raw(memory:NVMM), format=(string)NV12’
! nvegltransform ! nveglglessink

the result is:
