Member Function Documentation

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getFps()

double getFps ( )

Returns the camera's framerate.

This is a maximum theoretical: the actual performance will depend on the speed of the hardware.

◆ getNumOptions()

static int getNumOptions ( )
static

Returns the number of webcam options.

An "option" consists of a device plus a set of configuration parameters. For example, "Creative Webcam Live at 640x480, 30 fps" is an option.

◆ getOption()

static WebcamVideo getOption ( int  n)
static

Returns the nth webcam option.

◆ getOptions()

list getOptions ( )

◆ getPixelFormat()

str getPixelFormat ( )

Returns the camera's pixel format, as a FourCC code, if known.

◆ getSizeX()

int getSizeX ( )

Returns the camera's size_x.

◆ getSizeY()

int getSizeY ( )

Returns the camera's size_y.

◆ output()

output ( Ostream  out)

Outputs the WebcamVideo.

This function simply writes the name, size and FPS to the output stream.
