How to get information such as total video duration and bit rate with PHP

&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); ?>
