I’ve seen a few mentions of this in the archives, but never anything definitive.
I repeatedly find myself needing programmatic control over USB webcam parameters. Most specifically, the ability to turn off autofocus, adjust focus, turn off autoexposure, and adjust exposure.
I found in videoInput.h (https://github.com/openframeworks/openFrameworks/blob/master/libs/videoInput/include/videoInput.h) mention of a few functions, such as setVideoSettingCamera(). However, any attempt I make at trying to call this results in an error (can’t find member function, no such name, etc.).
Is there any way within the current oF to get access to these things? I’m on Windows, using C::B. If not, does anyone have any clues/pointers to share to get me started? This must be possible somehow, since the cameras themselves come with little GUIs to make the adjustments I need.
