PHP使用FFmpeg获取视频信息

<?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_matc
4000
h("/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'] + $da`这里写代码片`ta['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);
?>
