gstd when run from terminal plays pipeline but does not when started as a service.

[aaha74]

What I want:

1. Run gstd as a systemd service
2. From a remote computer, using a client over tcp be able to create and control pipeline

Summary of problem:

1. gstd runs from terminal and supports creation and control from remote client
2. when i run the same executable as a service, i am from a remote computer able to create pipeline but not play it.

What I have done

I have an Ubuntu 22.04 and have built & installed gstd daemon as per instructions. I used --prefix=/home/user/gstd during configure to get all binaries and libraries in one folder.

If i run the following from a terminal (pwd=/home/user/gstd/bin) ./gstd -t -a 10.10.10.104 -e

and get the following result: ############################## GstD version 0.15.2 Copyright (C) 2015-2021 RidgeRun (https://www.ridgerun.com)

Process 756624 died: No such process; trying to remove PID file. (/home/user/gstd_1/pid/gstd.pid) Log traces will be saved to /home/user/gstd_1/log/gstd.log. Detaching from parent process.

** (gstd:783257): CRITICAL **: 21:14:20.476: gstd_socket_stop: assertion 'session' failed ##############################

However from another computer on the lan if i run a gstd-client using command gstd-client -a 10.10.10.104 and run the following commands inside the gstd-client prompt, I am able to play the pipeline pipeline_create p1 pulsesrc ! pulsesink pipeline_play p1 pipeline_stop p1 pipeline_play p1

All the above works and I verify the pipeline by hearing my own voice when I speak on microphone.

If however I run the same gstd as a service. I am able to create the pipeline but not play it. My service file looks like the following ############################## [Unit] Description=G Streamer v7 Wants=default.target After=default.target
