I just add an camera ros package to handle csi camera with below commands
sudo apt-get install ros-noetic-cv-camera
When I launch the package it failed, any one knows how to fix this issue?
$ rosrun cv_camera cv_camera_node

This problem may also be caused by a refcounting bug in the

Hi,
In the sample width,height,framerate is set to 1920x1080p30. Probably your camera source does not support this mode. Please check which modes your camera support and configure width,height,framerate to fit the mode.
