PHP使用FFmpeg获取视频播放总时长与码率等信息

<?phpdefine('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];    $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);?>
