English translation:
Hello,
We are using a systemd service that starts an ISP-based video pipeline. The script looks like this:
[Unit]
Description=My user application
Requires=imx8-isp.service
After=imx8-isp.service
StartLimitIntervalSec=300
StartLimitBurst=3
[Service]
ExecStartPre=/bin/sleep 10
ExecStart=/usr/bin/run-my-qt-app.sh
Restart=always
[Install]
WantedBy=multi-user.target
We would now like to get rid of the "sleep 10" command, which was added because the isp.service does not communicate its "readiness" to systemd.
This is because the isp daemon (isp_media_server) is blocking.
One idea would be to replace the "sleep 10" command with a "isp_media_server" process check script that regularly checks for the existence of the process. However, in my opinion this is not the best way to do it.
Do you have any feedback on this?
Thank you very much,
