php sample code for using FFmpeg to obtain information such as total video playback duration and bitrate

FFmpeg is a set of open source computer programs that can be used to record, convert digital audio and video, and convert them into streams. Use LGPL or GPL license. It provides a complete solution for recording, converting and streaming audio and video. It contains the very advanced audio/video codec library libavcodec. In order to ensure high portability and codec quality, many codes in libavcodec were developed from scratch. This article shares with you how to use FFmpeg in PHP to read information such as video playback duration and bit rate. Friends in need can refer to it. Let’s take a look below.

Please note: passthru will be used in this article, and some virtual hosts may disable this command.

The code is as follows:

PHP

<?php
define(&#39;FFMPEG_PATH&#39;, &#39;/usr/local/ffmpeg2/bin/ffmpeg -i "%s" 2>&1&#39;);
 
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[&#39;duration&#39;] = $match[1]; //播放时间
    $arr_duration = explode(&#39;:&#39;, $match[1]);
    $data[&#39;seconds&#39;] = $arr_duration[0] * 3600 + $arr_duration[1] * 60 + $arr_duration[2]; //转换播放时间为秒数
    $data[&#39;start&#39;] = $match[2]; //开始时间
    $data[&#39;bitrate&#39;] = $match[3]; //码率(kb)
  }
  if (preg_match("/Video: (.*?), (.*?), (.*?)[,\s]/", $info, $match)) {
    $data[&#39;vcodec&#39;] = $match[1]; //视频编码格式
    $data[&#39;vformat&#39;] = $match[2]; //视频格式
    $data[&#39;resolution&#39;] = $match[3]; //视频分辨率
    $arr_resolution = explode(&#39;x&#39;, $match[3]);
    $data[&#39;width&#39;] = $arr_resolution[0];
    $data[&#39;height&#39;] = $arr_resolution[1];
  }
  if (preg_match("/Audio: (\w*), (\d*) Hz/", $info, $match)) {
    $data[&#39;acodec&#39;] = $match[1]; //音频编码
    $data[&#39;asamplerate&#39;] = $match[2]; //音频采样频率
  }
  if (isset($data[&#39;seconds&#39;]) && isset($data[&#39;start&#39;])) {
    $data[&#39;play_time&#39;] = $data[&#39;seconds&#39;] + $data[&#39;start&#39;]; //实际播放时间
  }
  $data[&#39;size&#39;] = filesize($file); //文件大小
  return $data;
}
 
//用法
$video_info = getVideoInfo(&#39;video.mp4&#39;);
print_r($video_info);
?>
