curl 192.168.178.225:554 results in:
curl: (7) Failed to connect to 192.168.178.225 port 554: Connection refused
would this be the expected error?
Can you try running from the hostOS console the following: curl 127.0.0.1:554. How about the same but from the container with the RTSP service listening on 554/tcp?
curl 127.0.0.1:554 results in the process finishing in about 1 minute without any output
the verbose curl -v 127.0.0.1:554 results in the output below. the HostOS seems to have a slightly different output, but nothing appears significant.
Balena HostOS:

just to be sure, i tried the same on the regular Ubuntu version. both container and host have the same response

* Closing connection 0Can you try sharing the logs from vlc?
I am guessing you are using the VLC desktop app on your laptop/PC - so starting it from the command line, with the verbose flag - and then trying to connect to the server, should give us some more insight. So vlc --verbose 2
2 would give us the most amount of logs.

[0000560552dce5a0] main playlist debug: nothing to playIt looks like VLC is connecting to the device, but there is a problem with the RTSP stream itself. Unfortunately I don’t see anything that points to a specific issue, but perhaps a member of the community will spot something. What command are you using to launch the RTSP server, and does that provide any output or log messages?
Here is a sample application that may be helpful to inspect: GitHub - balena-io-playground/capture-and-streaming: Demo of new video capture block and streaming block - on a Jetson Nano with a USB webcam attached, it streams (using gstreamer) to VLC on rtsp://192.168.1.162:8554/server (replace with your Jetson’s local IP address)
I will see if i can get the sample application working to verify that the issue lies with the streamer itself.
for reference, my application is based on the python examples of Nvidia (though it is heavily modified)
Thanks for the tip, the sample application works fine and seems to have some similarities with my streamer (though mine is in python). I will look into it
Glad that worked!
