从java中的视频中提取图像

Question

我想知道如何从使用JMF的视频中提取图像。

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; 
}
