Mac OS: take full control of your webcam (USB connection)

A task:

OS: Mac OS X 10.9+

Description:

  • There is a webcam connected to the Mac via USB. I need to find a way to access its brightness, panorama, color temperature, focus, etc.
  • I also need a way to apply image filters to the camera's video stream.
  • I need to be able to control the camera when it is in use by other programs such as Skype, so I can stream, for example, a high-contrast video stream on a Skype video call.
  • Reference app: https://itunes.apple.com/app/webcam-settings/id533696630?mt=12

Decision:

This is the question.

As far as I understood, I have to find a custom kext (driver) to do all this magic.

Could you please show me the right direction, libraries, drivers, etc.

You can use opencv library to capture camera frames, apply filters, etc. http://docs.opencv.org/2.4/doc/tutorials/introduction/display_image/display_image.html



Then you can submit a virtual camera that can connect to Skype, etc. http://download.cnet.com/Virtual-Webcam/3000-2348_4-75754338.html There are also many open source virtual webcams available. Hope this helps.
