Jmf 播放视频格式的有关问题（帮顶就给分）

Jmf 播放视频格式的问题（帮顶就给分）
JMF在抓取到视频摄像头后提示一下错误：
  Unable to handle format: YUV Video Format: Size = java.awt.Dimension[width=640,height=480] MaxDataLength = 614400 DataType = class [B yuvType = 32 StrideY = 1280 StrideUV = 1280 OffsetY = 0 OffsetU = 1 OffsetV = 3

Failed to realize: com.sun.media.PlaybackEngine@8c436b
Error: Unable to realize com.sun.media.PlaybackEngine@8c436b

我知道是格式的问题从而不能创建播放器，但是不知道该如何解决，希望能有人帮我解答
附部分代码：

Java code

  captureDeviceInfo=CaptureDeviceManager.getDevice("vfw:Microsoft WDM Image Capture (Win32):0");               mediaLocator=new MediaLocator("vfw://0");         imagePanel=new ImagePanel();           capture=new JButton("拍照");           capture.addActionListener(this);           DataSource ds = new DataSource();         ds.setLocator(mediaLocator);
