不好意思推了舊文....

我爬文了許久
但錯誤一直出現
No device found [ vfw:Microsoft WDM Image Capture (Win32):0]
Exception in thread "main" java.lang.NullPointerException
  at jmfdemo.Test.<init>(Test.java:46)
  at jmfdemo.Test.main(Test.java:82)

我用jm studio 有抓到
vfw:Microsoft WDM Image Capture (Win32):0

但程式碼就是一直出現錯誤

請各位大大解救
