Failed to run the launch file

[PrajnaM1]

When I run the command, roslaunch my_camera elp.launch
I get the following error:
/opt/ros/melodic/lib/nodelet/nodelet: symbol lookup error: /home/pr/catkin_ws/devel/lib//liblibuvc_camera_nodelet.so: undefined symbol: uvc_init
[FATAL] [1601784120.528561265]: Failed to load nodelet '/libuvc_cameraof typelibuvc_camera/driverto manager/nodelet_manager'

I just checked and had the same issue. What worked for me was running the following:

sudo apt-get install ros-melodic-libuvc-camera
source ~/.bashrc
source devel/setup.bash (assuming you are in your catkin ws)
roslaunch my_camera elp.launch

Thank you for the comment. I ran the 4 commands and I am still getting the same error. I tried with my laptop's integrated webcam and an Insta360 camera in webcam mode but I still get the same error. What could be the problem?

Sorry for the late reply. I think it will be best to reach out for some help debugging this in the libuvc_camera driver: https://github.com/ros-drivers/libuvc_ros
