JavaFX使用摄像头API的示例

在GITHUB上面有这样的示例：

它的网址是：https://github.com/sarxos/webcam-capture/tree/master/webcam-capture-examples/webcam-capture-javafx

我不知道大家是否可以访问的上这个链接，不知道有没有被墙了（因为我不在国内）。

如果有被墙的话，我上传了摄像头包，其中包含很多示例。可在这个链接上下载  http://download.csdn.net/detail/yizdream/8196815

当你附加你的LIB后，也就是摄像头包中的JAR,别忘了摄像头包里的LIB里的JAR一样要引用的。

看看示例吧，怎样在javaFX上使用这个包。

不过这里要感谢Rakesh Bhatt (rakeshbhatt10)分享了他的代码......
