PHP做视频网站，让程序自动实现视频格式转换、设置视频大小、生成视频缩略图

一、PHP实现转换

　　　在做视频网站的时候，最头痛的问题可能是格式转换、视频缩略图等。下面我将用PHP实现这一些功能。PHP是没有自带视频的函数，所以会用到第三方的软件工具来实现。

?

二、什么是FFmpeg

　　　FFmpeg是一个开源免费跨平台的视频和音频流方案，属于自由软件，采用LGPL或GPL许可证（依据你选择的组件）。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多codec都是从头开发的。

FFmpeg在Linux平台下开发，但它同样也可以在其它操作系统环境中编译运行，包括Windows、Mac OS X等。

这个项目最早由Fabrice Bellard发起，现在由Michael Niedermayer维护。许多FFmpeg的开发人员都来自MPlayer项目，而且当前FFmpeg也是放在MPlayer项目组的服务器上。项目的名称来自MPEG视频编码标准，前面的"FF“代表"Fast Forward“。更多详情》

/* 转视频?? */

$cmd="ffmpeg.exe -i tiwer_update_move.avi -ab 56 -ar 22050 -b 500 -r 15 -s 500x600 201112120089123.flv";?

?

exec($cmd);?

?

/*? 视频截图*/

$cmd="ffmpeg.exe -itiwer_update_move.avi -f image2 -ss 10 -s 600*500 -vframes 1 201112120089123.jpg";

exec($cmd);

?三、生成缩略图

?

include("ImageHelper.class.php");

?

/* 生成缩略图 */

$thumbnail?= new?ImageHelper();?

$thumbnail->resizeimage("2012121208123.jpg", 30,30, 0, "2012121208123_small.jpg");?
