FFmpeg is a video plug-in. We can use the FFmpeg interface to obtain relevant information about the video, including the playback time of the video, the bitrate of the video, the thumbnail of the video and the creation time of the video. This article introduces how to use PHP. FFmpeg interface obtains video information, friends in need can refer to it.
FFmpeg gets the thumbnail of the video file:
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 reads the video playback duration and bit rate
<?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]; $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 gets the total length time and creation of the video file Time
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 ); }
The above is the entire content of this article. I hope it will be helpful to everyone's learning, and I also hope everyone will support the PHP Chinese website.
