Tested it with the following pipelines:
[*] videotestsrc is-live=true do-timestamp=true ! capsfilter
caps="video/x-raw,width=1024,height=768,framerate=8/1" !
amcvidenc-omxk3videoencoderavc bitrate=1024 i-frame-interval=8 ! rtph264pay !
queue ! udpsink host=192.168.1.104 port=3057
[*] videotestsrc is-live=true do-timestamp=true ! capsfilter
caps="video/x-raw,width=1024,height=768,framerate=8/1" !
amcvidenc-omxk3videoencoderavc bitrate=1024 i-frame-interval=8 ! queue !
capssetter caps="video/x-h264,profile=baseline" !
amcviddec-omxk3videodecoderavc ! eglglessink

*** Note ***
1. Replace the encoder amcvidenc-omxk3videoencoderavc with the actual encoder
on your pad.
2. Replace the decoder amcviddec-omxk3videodecoderavc with the actual decoder
on your pad.
3. Replace IP "192.168.1.104" with the receiver's IP
