Hi,

I'm trying ro2_trt_pose on jetbot0.4.0 image. JETPACK version is 4.3. Any suggestion for below Gstreamer error?

jetbot@jetson-4-3:~$ ros2 run image_tools cam2image

Hi,

I don't see this problem after I install ROS2 Eloquent from debian package. https://index.ros.org/doc/ros2/Installation/Eloquent/Linux-Install-Debians/

I faced this problem with ROS2 Eloquent build from source. It looks ROS2 built wasn't correct. https://index.ros.org/doc/ros2/Installation/Eloquent/Linux-Development-Setup/

Thanks!
