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

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.
