I had the same issue, to solve it you need to do the following: 1- check the output type format for the USB camera you're working with. 2- Mine was mjpeg so I had to modify the usb_cam-test.launch which can be found under the following directory: /opt/ros/noetic/share/usb_cam/launch/usb_cam-test.launch 3- Change "yuyv" to "mjpeg" in the launch file 4- Run the following node rosrun usb_cam usb_cam_node _pixel_format:=mjpeg 5- It should be working well right now. You can double-check by doing: rosrun image_view image_view image:=/usb_cam/image_raw
