Without videorate I got the same problem:

gst-launch-1.0 -v v4l2src -v device=/dev/video4 !
image/jpeg,width=1920,height=1080,framerate=30/1 !  v4l2jpegdec !  
"video/x-raw, format=Y42B, width=1920, height=1080, colorimetry=1:4:7:1" !
videoconvert !
video/x-raw,width=1920,height=1080,format=I420,colorimetry=bt601 !  fakesink

Working
