This is a duplicate of can any dslr camera be used as webcam in ROS. I'm going to close it. If you disagree, and you feel this should remain open, please tell us why in a comment.
I think this one is about not finding the file, the other question is about permission denied.
Maybe so. That's why I asked for more information, and the possibility to re-open if it makes sense.
previously i was getting "permission denied" error but now i am getting the another error which you have closed.basically i am trying to run this command "rosrun usb_cam usb_cam_node" by connecting nikon DSLR and getting the above problem.
I've re-opened it, but could you please go back to your previous question and answer some of the outstanding questions there? Especially the comments by @lucasw and @Mehdi about checking whether
/dev/videoX
even exists.
