php上传视频并自动转码成FLV功能实现！
最近做学校电视台网站，想开发让学生上传自己的DV作品的功能，用php实现，转码成flv格式，就像youku，tudou那样，查找了相关资料，发现了ffmpeg这个软件好像可以实现 ，但说的都很简单，只给出了一些参数，并没有给出实例，以及怎么与php结合，希望有人能教我：
1、安装与配置ffmpeg（或者其他可行软件）
2、给出一个简单实例（例：将test.rmvb上传并转码成flv，之后再添加到数据库）
回复讨论(解决方案)
没记错的话国外有这种框架 不过好像是收费的.
有一种比较正统的做法，原理大致是这样的：在你的服务器上安装一个可以将很多种格式的视频文件转换为FLV文件的软件，研究其命令行调用的各种参数，然后在你的PHP代码中用system命令调用即可。
