Hello everyone, I am writing because I have the following query. What is the proper way to run a deepstream application at boot time?
The application I want to run is on a remote device (Jetson Nano), which reads two sources (RTSP streams) of video, and then performs the sequence pgie-> tracker-> analytics. Finally it publishes the results of “LineCrossing” of the analytics plugin, in an AWS IoT Core (MQTT) topic. In parallel to the publication of messages, in a second sink, a streaming (RTSP) of the processed video is performed.
The results obtained are the following:
If I manually run the application: It runs correctly, publishing messages at intervals of 10 seconds (every 250 frames).
If I manually run the service (sudo systemctl start deepstream.service): The service runs, however from what I can see, the frequency of sending published messages is not the desired one (app every 16 seconds). I have also been able to observe some messages published twice.
When the service tries to start after booting, it generates a series of errors that can be seen below.
I have seen that when I run the application and the input source is a video file (not RTSP source), apparently the service manages to start correctly after booting. The configured service file is as follows:
[Unit] Description=Deepstream Service After=network.target [Service] Type=simple ExecStart=<Path to Application + Args> User=nano WorkingDirectory=<Path to Application> Restart=on-failure StandardOutput=syslog StandardError=syslog [Install] WantedBy=multi-user.target
Has anyone had similar problems or have any idea that it may be generating errors?
