Im working on this project :
https://www.hackster.io/jonmendenhall/jetson-nano-search-and-rescue-ai-uav-9ca547
At some point I will need to mount my camera (waveshare ; IMX219-77IR) on top of the drone and I would like to use Windows or Linux outside of nomachine (because the nano will be in headless mode),to display what the camera sees when the drone is flying. For this reason I'm trying to configure gstreamer with RTSP to start a streaming server on the Ubuntu 18.04 that I have installed on the jetson nano. (Keep in consideration that I will attach to the nano the “huawei e3372 4g” dongle to provide to the drone a mobile connection,instead of a wi-fi connection and the encoder used may have an impact on the performance of the video streaming).
To achieve my goal this is the thread that I'm following :
https://forums.developer.nvidia.com/t/vlc-playing-gstreamer-flow/51694/6
At some point DaneLLL says :
Please also try test-launch.c @ https://github.com/GStreamer/gst-rtsp-server/blob/master/examples/test-launch.c 136
Target
sudo apt-get install libgstrtspserver-1.0 libgstreamer1.0-dev gcc test-launch.c -o test-launch $(pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0) ./test-launch “videotestsrc ! omxh265enc ! rtph265pay name=pay0 pt=96”
Host Open network stream rtsp://<TARGET_IP_ADDRESS>:8554/test via VLC
it didn't work,but I found the reason and I fixed it. All my steps were correct, except that I was using the latest version of the example, which uses the latest API. Since most Jetson boards come with Gstreamer 1.16 pre-installed, I used that same version of the example:
https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server/-/blob/1.16/examples/test-launch.c
now,doing :
./test-launch "videotestsrc ! omxh265enc ! rtph265pay name=pay0 pt=96"
I got this output : stream ready at rtsp://127.0.0.1:8554/test
at this point the problem is that I'm not able to connect to that address using VLC. I checked if the ports were open (I have opened them on the router side)

But VLC still doesn't want to connect to :
rtsp://127.0.0.1:8554/test
rtmp://127.0.0.1:1935/live/test
and :
rtsp://192.168.1.3:8554/test
rtmp://192.168.1.3:1935/live/test
after a further investigation, I found that :
root@ziomario-desktop:~/Scrivania# /usr/bin/ffmpeg -i rtsp://192.168.1.3:8554/test -vcodec copy -acodec copy -f flv rtmp://192.168.1.3:1935/live/test
[flv @ 0x557dfbdd80] Video codec hevc not compatible with flv
Could not write header for output file #0 (incorrect codec parameters ?): Function not implemented
so,could this be the reason ? how to fix that ? thanks.
