Error when running single_stream sample application in Docker container created using DockerFile.deepstream.ros2.eloquent

[ctslick]

I've built a Docker container using this Dockerfile from the repo:
https://github.com/NVIDIA-AI-IOT/ros2_jetson/blob/main/docker/DockerFile.deepstream.ros2.eloquent

I then follow steps here (to run an example) inside the container:
https://github.com/NVIDIA-AI-IOT/ros2_deepstream

1. cd /workspace/ros2_ws/src/ros2_deepstream/
2. colcon build
3. source /opt/ros/eloquent/setup.bash
4. . install/setup.bash
5. ros2 run single_stream_pkg single_stream --ros-args -p input_source:="/dev/video0"

Steps 1-4 run fine, but running step #5 I receive this error:

This shared object file () is located here (inside the container);
root@ubuntu:/# find . -name libgstreamer-1.0.so.0
./usr/lib/aarch64-linux-gnu/libgstreamer-1.0.so.0
./usr/lib/aarch64-linux-gnu/tegra/libgstreamer-1.0.so.0

So I tried:

• export LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu/libgstreamer-1.0.so.0:$LD_LIBRARY_PATH
• (receive same error as above)
• export LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu/tegra/libgstreamer-1.0.so.0:$LD_LIBRARY_PATH
• (receive same error as above)

I'm not sure where to go from here. It seems the container is not built correctly to run code from the ros2_deepstream repo, even though that is the intended purpose of these containers?
