小编给大家分享一下php+ffmpeg怎么获取视频缩略图、视频分辨率等相关信息，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

前言

ffmpeg是一款开源、跨平台的视频处理程序，可用在Windows、mac、linux等平台，可以方便的运用多种语言脚本来调用其执行视频的操作。

下面介绍使用ffmpeg获取视频首帧的方法。

&1"; //调用php的exec方法去执行脚本exec($shell, $output, $return_val); //获取输出信息print_r($output);

FFmpeg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);   //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;   $result = system($str); }

Fmpeg读取视频信息

&1');  function getVideoInfo($file) {     $command = sprintf(FFMPEG_PATH, $file);     ob_start();  passthru($command);  $info = ob_get_contents();  ob_end_clean();    $data = array();  if (preg_match("/Duration: (.*?), start: (.*?), bitrate: (\d*) kb\/s/", $info, $match)) {    $data['duration'] = $match[1]; //播放时间    $arr_duration = explode(':', $match[1]);    $data['seconds'] = $arr_duration[0] * 3600 + $arr_duration[1] * 60 + $arr_duration[2]; //转换播放时间为秒数    $data['start'] = $match[2]; //开始时间     $data['bitrate'] = $match[3]; //码率(kb)  }  if (preg_match("/Video: (.*?), (.*?), (.*?)[,\s]/", $info, $match)) {    $data['vcodec'] = $match[1]; //视频编码格式    $data['vformat'] = $match[2]; //视频格式    $data['resolution'] = $match[3]; //视频分辨率    $arr_resolution = explode('x', $match[3]);    $data['width'] = $arr_resolution[0];    $data['height'] = $arr_resolution[1];  }  if (preg_match("/Audio: (\w*), (\d*) Hz/", $info, $match)) {    $data['acodec'] = $match[1]; //音频编码    $data['asamplerate'] = $match[2]; //音频采样频率  }  if (isset($data['seconds']) && isset($data['start'])) {    $data['play_time'] = $data['seconds'] + $data['start']; //实际播放时间  }  $data['size'] = filesize($file); //文件大小  return $data;}  //用法$video_info = getVideoInfo('video.mp4');print_r($video_info);?>

Fmpeg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   );}

另外一种方法

ffprobe -v quiet -print_format json -show_format -show_streams test.mp4

结果
