PHP利用FFmpeg读取视频播放时长和码率等信息

复制代码 代码如下://获得视频文件的缩略图function getVideoCover {if$time = '1';//默认截取第一秒第一帧$strlen = strlen;// $videoCover = substr;// $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;}//获得视频文件的总长度时间和创建时间function getTime{$vtime = exec("ffmpeg -i ".$file." 2>&1 | grep 'Duration' | cut -d ' ' -f 4 | sed s/,//");//总长度$ctime = date("Y-m-d H:i:s",filectime;//创建时间//$duration = explode;// $duration_in_seconds = $duration[0]*3600 + $duration[1]*60+ round;//转化为秒return array('vtime'=>$vtime,'ctime'=>$ctime);}

例子,FFmpeg读取视频播放时长和码率

代码如下:

 代码如下

<?php
define('FFMPEG_PATH', '/usr/local/ffmpeg2/bin/ffmpeg -i "%s" 2>&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]金沙官网线上,;
        $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);
?>
