320*240*3 = 230400, this is too big to fit in a udp packet.

appsrc/appsink doesn't work with gst-launch. otherwise it will work.

Try this:

gst-launch videotestsrc ! ffmpegcolorspace ! rtpvrawpay ! udpsink 
host=127.0.0.1

and then:

gst-launch udpsrc caps="application/x-rtp, media=(string)video, 
clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)RGB, 
depth=(string)8, width=(string)320, height=(string)240, 
colorimetry=(string)SMPTE240M" ! rtpvrawdepay ! ffmpegcolorspace ! 
autovideosink
