Class ImageFormat

java.lang.Object

au.edu.jcu.v4l4j.ImageFormat

public class ImageFormat
extends Object

Objects of this class represent an image format (YUV, RGB, GREY, BGR, ...) and its supported capture resolutions and frame intervals. ImageFormat objects have three members: a name, a unique index, and a ResolutionInfo object which provides information on supported capture resolutions and frame intervals for this format. A list of known image format indexes can be found in V4L4JConstants.IMF_*. ImageFormats are not directly instantiated. Instead, they can be enumerated by instantiating a VideoDevice, and checking the DeviceInfo object associated with it:

VideoDevice vd = new VideoDevice("/dev/video0");
vd.init();
List fmts = vd.getDeviceInfo().getFormatList().getNativeFormats();
for(ImageFormat im: fmts)
System.out.println("Format name: "+im);
vd.release();
See the ImageFormatList documentation for more information.
