Not able to launch pipeline_node

[sarithabapuram]

Hi,

Not able to launch the gst pipeline node with launch file, could you please share some example for the same.

~/workspaces/gstreamer_ws$ ros2 launch gst_bridge example.launch.py
[INFO] [launch]: All log files can be found below /home/avlabs/.ros/log/2023-03-24-05-21-48-934184-nuvo-one-234474

Thanks in Advance

Your logs look normal right up until the error.
-11 looks like a segfault, which CPU are you using?

[sarithabapuram]

Intel(R) Xeon(R) E-2278GE CPU

And I kept only audio_test as part of simple_bins, and removed rest others including webrtc_example_bin section

That does narrow it down a lot.
The only code that example uses is the python pipeline host, it sounds like your gstreamer is having a bad time

Does the audio_test pipeline work on its own through gst-launch?

$ gst-launch-1.0 audiotestsrc volume=0.3 is-live=true wave=red-noise ! queue ! audioconvert ! alsasink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Redistribute latency...

I tested with one of the working pipeline
gst-launch-1.0 --gst-plugin-path=install/gst_bridge/lib/gst_bridge/ v4l2src device=/dev/bench_cam_1 ! 'video/x-raw, width=1920, height=1020' ! videoconvert ! rosimagesink ros-topic="image_raw" ros-node-name="bench_cam_1"
