FFmpeg

复制代码 代码如下:
//获得视频文件的缩略图
function getVideoCover($file,$time,$name) {
     if(empty($time))$time = '1';//默认截取第一秒第一帧
     $strlen = strlen($file);
     // $videoCover = substr($file,0,$strlen-4);
     // $videoCoverName = $videoCover.'.jpg';//缩略图命名
     //exec("ffmpeg -i ".$file." -y -f mjpeg -ss ".$time." -t 0.001 -s 320x240 ".$name."",$out,$status);
     $str = "ffmpeg -i ".$file." -y -f mjpeg -ss 3 -t ".$time." -s 320x240 ".$name;
     //echo $str."";
     $result = system($str);
     }

//获得视频文件的总长度时间和创建时间
function getTime($file){
     $vtime = exec("ffmpeg -i ".$file." 2>&1 | grep 'Duration' | cut -d ' ' -f 4 | sed s/,//");//总长度
     $ctime = date("Y-m-d H:i:s",filectime($file));//创建时间
     //$duration = explode(":",$time);
     // $duration_in_seconds = $duration[0]*3600 + $duration[1]*60+ round($duration[2]);//转化为秒
     return array('vtime'=>$vtime,
     'ctime'=>$ctime
     );
}
