ffmpeg php

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, including libavcodec ensures high portability and encoding and decoding quality.

This article will introduce how to use php to call ffmpeg to obtain video information. To call ffmpeg, you first need to install ffmpeg on the server. The installation method is very simple and you can search by yourself.

The code is as follows:

<?php// 定义ffmpeg路径及命令常量define(&#39;FFMPEG_CMD&#39;, &#39;/usr/local/bin/ffmpeg -i "%s" 2>&1&#39;);/**
 * 使用ffmpeg获取视频信息
 * @param  String $file 视频文件
 * @return Array
 */function getVideoInfo($file){
    ob_start();
    passthru(sprintf(FFMPEG_CMD, $file));    $video_info = ob_get_contents();
    ob_end_clean();    // 使用输出缓冲，获取ffmpeg所有输出内容
    $ret = array();    // Duration: 00:33:42.64, start: 0.000000, bitrate: 152 kb/s
    if (preg_match("/Duration: (.*?), start: (.*?), bitrate: (\d*) kb\/s/", $video_info, $matches)){        $ret[&#39;duration&#39;] = $matches[1]; // 视频长度
        $duration = explode(&#39;:&#39;, $matches[1]);        $ret[&#39;seconds&#39;] = $duration[0]*3600 + $duration[1]*60 + $duration[2]; // 转为秒数
        $ret[&#39;start&#39;] = $matches[2]; // 开始时间
        $ret[&#39;bitrate&#39;] = $matches[3]; // bitrate 码率 单位kb
    }    // Stream #0:1: Video: rv20 (RV20 / 0x30325652), yuv420p, 352x288, 117 kb/s, 15 fps, 15 tbr, 1k tbn, 1k tbc
    if(preg_match("/Video: (.*?), (.*?), (.*?)[,\s]/", $video_info, $matches)){        $ret[&#39;vcodec&#39;] = $matches[1];     // 编码格式
        $ret[&#39;vformat&#39;] = $matches[2];    // 视频格式
        $ret[&#39;resolution&#39;] = $matches[3]; // 分辨率
        list($width, $height) = explode(&#39;x&#39;, $matches[3]);        $ret[&#39;width&#39;] = $width;        $ret[&#39;height&#39;] = $height;
    }    // Stream #0:0: Audio: cook (cook / 0x6B6F6F63), 22050 Hz, stereo, fltp, 32 kb/s
    if(preg_match("/Audio: (.*), (\d*) Hz/", $video_info, $matches)){        $ret[&#39;acodec&#39;] = $matches[1];      // 音频编码
        $ret[&#39;asamplerate&#39;] = $matches[2]; // 音频采样频率
    }    if(isset($ret[&#39;seconds&#39;]) && isset($ret[&#39;start&#39;])){        $ret[&#39;play_time&#39;] = $ret[&#39;seconds&#39;] + $ret[&#39;start&#39;]; // 实际播放时间
    }    $ret[&#39;size&#39;] = filesize($file); // 视频文件大小
    $video_info = iconv(&#39;gbk&#39;,&#39;utf8&#39;, $video_info);    return array($ret, $video_info);

}// 输出视频信息$video_info = getVideoInfo(&#39;myvideo.avi&#39;);
print_r($video_info[0]);?>
