Method Details

putImage

public static void putImage(long nativePtr,
 byte[] buffer)

detectCamerasCount

public static int detectCamerasCount()

detectCameras

public static int detectCameras(int[] indexes,
 int[] frontFacing,
 int[] orientation)

selectNearestResolutionAvailable

public static int[] selectNearestResolutionAvailable(int cameraId,
 int requestedW,
 int requestedH)

Return the hw-available available resolution best matching the requested one. Best matching meaning : - try to find the same one - try to find one just a little bigger (ex: CIF when asked QVGA) - as a fallback the nearest smaller one

Parameters:

cameraId - Camera id

requestedW - Requested video size width

requestedH - Requested video size height

Returns:

int[width, height] of the chosen resolution, may be null if no resolution can possibly match the requested one

activateAutoFocus

public static void activateAutoFocus(Object cam)

startRecording

public static Object startRecording(int cameraId,
 int width,
 int height,

 Object surf)

selectNearestResolutionAvailableForCamera

protected static int[] selectNearestResolutionAvailableForCamera(int id,
 int requestedW,
 int requestedH)

applyCameraParameters

protected static void applyCameraParameters(android.hardware.Camera camera,
 int width,
 int height,
