Functions

func DetectCameras

func DetectCameras()

DetectCameras detects and files the index of available cameras. Take into account current camera if already on

func EndCameraDetect

func EndCameraDetect()

EndCameraDetect stop the associated goroutine turning on camera

func RestartCamera

func RestartCamera(rootdir string, shutdown <-chan interface{}, wg *sync.WaitGroup)

RestartCamera stops and restarts the camera in a sync fashion (wait for the camera to stop before sending the Start signal)

func StartCameraDetect

func StartCameraDetect(rootdir string, shutdown <-chan interface{}, wg *sync.WaitGroup)

StartCameraDetect creates a go routine handling web cam recording and image generation

func WipeScreenshots

func WipeScreenshots(dir string)

WipeScreenshots removes screenshots in dir unconditionally (existing or not)

Types

type RenderedImage

type RenderedImage struct {
	RenderingMode datastore.RenderMode
	// contains filtered or unexported fields
}

RenderedImage abstract if we are using opencv or direct image blending

func (*RenderedImage) DrawFace

func (r *RenderedImage) DrawFace(face *opencv.Rect, num int, cvimage *opencv.IplImage)

DrawFace renders a new face on top of image depending on rendering type

func (*RenderedImage) Save

func (r *RenderedImage) Save()

Save current image in destination file
