How to get information such as total video duration and bit rate with PHP

How does PHP obtain information such as the total duration and bit rate of the video? 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. I hope to be helpful.

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);
?>
