Pixelation on RTSP stream

Thank you all for the replies.

The gst pipeline I tried to run is as follows : `gst-launch-1.0 rtspsrc
location=rtsp://--- ! rtpjitterbuffer ! rtph264depay ! queue ! h264parse !
avdec_h264 ! videoscale ! fpsdisplaysink sync = false video-sink=
"autovideosink"`

I am still getting pixelation/ghosting effects when there is any form of
movement.
