使用Java调用摄像头进行拍照源码

[需求：要直接使用SWING来抓高拍仪的图，亦即支持摄像头。 曾经试过要用JMF2，但是安装使用复杂不说，貌似还有windows版本不兼容问题。试了试，部署后恶评如潮。 最终决定

使用Java调用摄像头进行拍照源码，并且有JMF下载地址。

JMF安装文件下载地址：

推荐软件

用java开发的一款功能强大的开源的远程控制软件，最近又升级了，[ 一、JMF简述        JMF(Java Media Framework)是Java媒体框架，包含了许多用于处理多媒体 的API可以让基于JAVA的应用实现音频、视频的捕捉、处理、播放、传输等功添加了许多使用的功能，而且代码也有了很大程度的优化。可以实现

生成服务器、修改上线主机名称、屏幕监视，屏幕控制、主动连接、上传文件、下载文件、 远程命令、远程任务管理器、发送警告、相互聊天、换皮肤、版本升级提醒等功能，通过该软件可以实现用一台电脑同时控制多台电脑，也可以多台电脑控制同一台电脑等。

[          java web程序中JMF能在windows中成功捕获USB摄像头拍照，但是把web程序放在linux中测试就获取不到驱动了，难道JMF获取的是本地摄像头驱动，我做的是B/S系统，
