Hi I am using GCC and linux to compile my opencv code. I am getting this error when I use the following commands

VideoCapture cam(1);
int fps=cam.get(CV_CAP_PROP_FPS);

Please help me out.

HIGHGUI ERROR: V4L2: Unable to get property <unknown property string>(5) - Invalid argument
I get the output as -1 for fps

However, if I run the same code in Visual Studio, it works fine.
