I want to use MIPI Camera read image do YOLO image recognition and use ROS2 publish/subscrlibe information, but the following error message often appears.
(test:6922): GStreamer-WARNING **: 07:50:09.916: Failed to load plugin '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstnvarguscamerasrc.so': /lib/aarch64-linux-gnu/libGLdispatch.so.0: cannot allocate memory in static TLS block

This is how I read the image
