php上传视频并自动转码成FLV效能实现
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)
------解决方案--------------------
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。
