Cannot create RTSP stream on service boot

Autonomous Machines Jetson & Embedded Systems Jetson Nano

Hi everyone, I’m trying to send a pi camera stream on the network with RTSP protocol and i would like the stream to be created when my jetson nano boots up.

The simple command i would like to execute on startup is the following :

/home/eseo/RTSP/gst-rtsp-server/examples/test-launch "nvarguscamerasrc sensor-id=0 ! video/xraw(memory:NVMM) width=1920 height=1080 framerate=30/1 format=NV12 ! omxh264enc iframeinterval=15 ! h264parse ! rtph264pay name=pay0 pt=96"

Please note that this command execute well and i’m able to retrieve the RTSP stream when launch directly on the jetson.

I’ve followed this tutorial for creating the service: How to run a script on boot - #4 by mdegans

i created this script createRTSP.sh:

#!/bin/bash 

# This script runs a command to create an RTSP stream for the PI camerea 

echo "Creating RTSP stream..." 

/home/eseo/RTSP/gst-rtsp-server/examples/test-launch "nvarguscamerasrc sensor-id=0 ! video/xraw(memory:NVMM) width=1920 height=1080 framerate=30/1 format=NV12 ! omxh264enc iframeinterval=15 ! h264parse ! rtph264pay name=pay0 pt=96"  

echo "RTSP stream closed"

and the service file is the following:

[Unit] 
After=network.target 
Description="Creating RTSP stream on startup" 
[Service] 
ExecStart=/usr/local/bin/createRTSP.sh 
User=cameraRTSP 
[Install] 
WantedBy=multi-user.target

After launching the service and checking the status with this command:

sudo systemctl status cameraRTSP

I’m getting these error and I’m not able to retrieve the video stream from the server:

Can you help me resolve those errors?

Hi,
Please refer to Jetson Nano FAQ

Q: How to autorun an app or commands at startup?

There are several use-cases and please give it a try.

I did the setup with rc.local and wrote my command in the rc.local file. The stream launches well at start-up. Thx!
