Hi
I am not good at gstreamer.
This is my code running at Jetson nano to stream to other device which IP address is 192.168.18.18.
gst-launch-1.0 v4l2src device=/dev/video0 \
! "video/x-raw, format=(string)UYVY, width=(int)2592, height=(int)1944,framerate=24/1" \
! nvvidconv \
! "video/x-raw(memory:NVMM),format=(string)I420" \
! nvv4l2h264enc maxperf-enable=true insert-vui=true insert-sps-pps=1 bitrate=10000000 \
! h264parse \
! rtph264pay \
! tcpclientsink host=192.168.18.18 port=38298 sync=false
Below is the gstreamer code running at Windows 10
gst-launch-1.0 -v tcpserversrc host=192.168.18.18 port=38298 ! application/x-rtp, media=video, clock-rate=90000, encoding-name=(string) H264, payload = 96 ! rtph264depay ! queue ! avdec_h264 ! fpsdisplaysink sync = false
This is the error message from Jetson nano terminal
This is the error info from Windows 10
Would you please let me know what’s wrong with it and how sort it out?
Thanks

RTP relies on UDP packetization, it would not work with TCP.
You may try another container such as gdp:
Receiver:
gst-launch-1.0 -v tcpserversrc host=192.168.18.18 port=38298 ! gdpdepay ! h264parse ! avdec_h264 ! fpsdisplaysink text-overlay=0
Sender (Jeston):
gst-launch-1.0 -v v4l2src device=/dev/video0 ! "video/x-raw, format=(string)UYVY, width=(int)2592, height=(int)1944,framerate=24/1" ! nvvidconv ! "video/x-raw(memory:NVMM),width=2592,height=1944,framerate=24/1,format=I420" ! nvv4l2h264enc maxperf-enable=true insert-vui=true insert-sps-pps=1 bitrate=10000000 ! h264parse ! gdppay ! tcpclientsink host=192.168.18.18 port=38298 sync=false
Thank you very much for your kind support.
The one you suggested works with a minor issue of the frame rate is varies too much especial at the start up. Please look at the frame rate (y axis) vs frame rendered (x axis) chart below
I removed the gdppay and gdpdepay on the script. It works better than with gdppay / gdpdepay comparing the frame rate vs frame rendered. look at the chart below:
Why the gdppay / gdpdepay resulted the frame rate varies significantly? what is major function of gdppay /gdpdepay?
Thanks

Further test found, after 5 minutes later
WARNING: from element /GstPipeline:pipeline0/GstFPSDisplaySink:fpsdisplaysink0/GstAutoVideoSink:fps-display-video_sink/GstD3DVideoSink:fps-display-video_sink-actual-sink-d3dvideo: A lot of buffers are being dropped.

There may be a timestamping problem, or this computer is too slow.
This issue applied to with and without gdppay /gdpdepay. but more frequently occured at the script I removed gdppay /gdpdepay.
I don’t think my computer is too slow as it is Intel core i7 8th gen CPU with Nivideo GeForce GTX graphic card and 16 GB RAM. Is it the timestamping problem. How can I fix it?
Thanks

You may try matroskamux/matroskademux instead of gdppay/gdpdepay, or both (matrsokamux → gdppay / gdpdepay → matroskademux).
