Network Streaming (RTSP) but No Display in Receiving Side

I try to stream, but I don't see any display in receiving side. This is my diagram:

One Image --> RTSP using UDP (using GStreamer) --> ?

Here is my command line and output in Terminal:

Sending (Server)

I don't see any error (or error in output I just not notice?) in output, but there is no display. I actually performed [the Diagnostic] from GStreamer to verify my GStreamer installation and it is good. I also switched computer between sending and receiving sides.

I am expecting a video play the image from sending side at receiving computer.

What I miss in my GStreamer pipelines? Thanks.

Runtime Environment
OS: Ubuntu 18.04 receiving and 16.04 sending
GStreamer: 1.14.5 receiving and 1.8.3 sending

Solution

You may try rtph263pay instead of rtph263ppay.

The following works for me:

Sender:

gst-launch-1.0 -v multifilesrc location=./IMG_7995.JPG loop=true ! jpegdec ! videoconvert ! videoscale ! videorate ! video/x-raw,framerate=30/1 ! avenc_h263 ! h263parse ! rtph263pay pt=96 ! udpsink host=192.168.3.30 port=6000

Receiver (192.168.3.30):

gst-launch-1.0 -v udpsrc address=192.168.3.30 port=6000 ! application/x-rtp,encoding-name=H263 ! rtph263depay ! h263parse ! avdec_h263 ! queue ! xvimagesink
