Make sure to test your pipeline with fakesink first (and GST_DEBUG=2),
you cannot see that warnings or the error in this mode. Here's a
reference using public URI that I know works:

gst-launch-1.0 -q  uridecodebin caps=video/x-raw uri=rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov ! fdsink | gst-launch-1.0 fdsrc ! rawvideoparse format=nv12 width=240 height=160 ! videoconvert ! autovideosink sync=0
