I have to turn the flash on using openCV. I have tried:
VideoCapture mCamera;
mCamera = new VideoCapture(Highgui.CV_CAP_ANDROID);
mCamera.set(Highgui.CV_CAP_PROP_ANDROID_FLASH_MODE, Highgui.CV_CAP_ANDROID_FLASH_MODE_TORCH);
There are no errors, but the flash does not turn on. Thank you in advance for your help.
