windows下ffmpeg-php装配

windows下ffmpeg-php装配

windows下ffmpeg-php安装

工作用到获取视频时长，需要在windows下扩展ffmpeg

在网上找的全是支持32位的系统，我是64位win7的 php版本为5.2.4

下载32位下包http://download.csdn.net/detail/xiao_bai8/7027699，打开有avcodec-51.dll、avformat-51.dll、avutil-49.dll、pthreadGC2.dll、php_ffmpeg.dll

把php_ffmpeg.dll还是放到php/ext下

剩下的四个文件放到C:\Windows\SysWOW64下，之前是放到C:\Windows\System32，但是64位没反映

代码测试：

"getFrameCount: " . $ffmpegInstance->getFrameCount()."

"getFrameRate: " . $ffmpegInstance->getFrameRate()."

"getFilename: " . $ffmpegInstance->getFilename()."

"hasAudio: " . $ffmpegInstance->hasAudio();
 
 7.执行后如果拿到视频的一些信息如下就表示环境配置成功了，那我们就可以开始开发我们的视频转换了。
 
执行结果：
