php使用FFmpeg接口获取视频的播放时长、码率、缩略图以及创建时间

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);
     // $videoCover = substr($file,0,$strlen-4);
     // $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.\"</br>\";
     $result = system($str);
     }

Fmpeg读取视频播放时长和码率

<?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 http://www.manongjc.com
        $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
     );
}
