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：

getDuration()."
" ."getFrameCount: " . $ffmpegInstance->getFrameCount()."
" ."getFrameRate: " . $ffmpegInstance->getFrameRate()."
" ."getFilename: " . $ffmpegInstance->getFilename()."
" ."getComment: " . $ffmpegInstance->getComment()."
" ."getTitle: " . $ffmpegInstance->getTitle()."

" ."getAudioCodec: " . $ffmpegInstance->getAudioCodec()."
" ."getAudioChannels: " . $ffmpegInstance->getAudioChannels()."
" ."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： getDuration: 811.13336181641		//时长getFrameCount: 12167			//帧计数getFrameRate: 15			//帧速率getFilename: C:\wamp\www\top10.mp4	//文件名路径getComment:				//评论getTitle:getAuthor:getCopyright:getArtist:getGenre:getTrackNumber: 0getYear: 0getFrameHeight: 240getFrameWidth: 320getPixelFormat: yuv420p			//像素格式getBitRate: 269769			//比特率getVideoBitRate:getAudioBitRate:getAudioSampleRate: 48000getVideoCodec: mpeg4			//视频编解码器getAudioCodec: mpeg4aacgetAudioChannels: 2hasAudio: 1
