从java中的视频中提取图像

Question

我想知道如何使用JMF从视频中提取图像。

Answer 1

Player player = Manager.createRealizedPlayer(cdi.getLocator());
player.start();
FrameGrabbingControl frameGrabber = (FrameGrabbingControl) player.getControl("javax.media.control.FrameGrabbingControl");


//////////////////////////////

private Image grab() {
Buffer buf = frameGrabber.grabFrame();
// Convert frame to an buffered image so it can be processed and saved
Image img = (new BufferToImage((VideoFormat) buf.getFormat()).createImage(buf));
    return img;
}
