Gstreamer example project is not working. (/subprojects/gst-rtsp-server/examples/test-onvif-server)

Question

I was trying to run the gstreamer example project from the /subprojects/gst-rtsp-server/examples/test-onvif-server.

$ ./subprojects/gst-rtsp-server/examples/test-onvif-server ~/Downloads/file_example_MP4_480_1_5MG.mp4

And I got this output in the terminal. "stream ready at rtsp://127.0.0.1:8554/test".

Then I opened the link in the Totem video player. but it showed the following prints in the terminal.

stream ready at rtsp://127.0.0.1:8554/test
0:00:05.681326198  6322 0x560ab751ccc0 ERROR           onvif-server test-onvif-server.c:496:create_replay_bin: Could not create element filesrc

What causing this issue? any help would be appreciated.

Answer 1

The problem arose from the incorrect configuration of environment variables, resulting in GStreamer not functioning as intended.

To resolve this issue, please execute either meson devenv -C <builddir> or ./gst-env.py. These commands will correctly set up the environment variables necessary for GStreamer to operate effectively.
