can any dslr camera be used as webcam in ROS
i am using a dslr camera as a webcam in ros but i am getting this error
[ERROR] [1459312203.054820640]: Cannot open '/dev/video0': 13, Permission denied.
Please help me
It's worth making sure
/dev/video0
actually exists, and a standard webcam viewer can open and view it.@rak: please do what @lucasw suggests. That is the first thing you should do.
@lucasw: i tried this command "ls /dev/vid" after connecting webcam and get this"/dev/video0 " but when i do same with my dslr camera i get this error "ls: cannot access /dev/vid: No such file or directory "
Does your dslr even support being used as a webcam? Linux may not support it even if it can be used as a webcam in Windows.
i have nikon D5300 which is working in ubuntu through darktable software
