Processing 2.1.1 无法使用video和movie问题解决方案

升级到2.1.1后，尝试着运行了一下sample中的video和movie，结果都报错，上网搜了一下，找到解决方法。

1. 首先来看movie的错误，如下：

这种错误是由于movie例子带的jna版本不对造成的，用3.5.1版本的jna替换C:\XXXX\processing-2.1.1\modes\java\libraries\video\library目录下的jna.jar即可。

2.video错误

video的错误相对movie error来说相对容易解决，安装最新版的Quicktime和WinVDIG即可，需要注意的是，安装Quicktime的时候一定要选择Quicktime for JAVA，否则一定会报错。
