php+ffmpeg怎么获取视频缩略图、视频分辨率等相关信息

小编给大家分享一下php+ffmpeg怎么获取视频缩略图、视频分辨率等相关信息，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

前言

ffmpeg是一款开源、跨平台的视频处理程序，可用在Windows、mac、linux等平台，可以方便的运用多种语言脚本来调用其执行视频的操作。

php+ffmpeg怎么获取视频缩略图、视频分辨率等相关信息

下面介绍使用ffmpeg获取视频首帧的方法。

<?php//待处理视频$in_file='https://mip.qiaqa.com/uploads/article/2022/03/03/5057.html';//shell脚本$shell="ffmpeg-i$in_file-y-fimage2-ss00:00:01-vframes1$out_file2>&1";//调用php的exec方法去执行脚本exec($shell,$output,$return_val);//获取输出信息print_r($output);

FFmpeg获得视频文件的缩略图

functiongetVideoCover($file,$time,$name){if(empty($time))$time='1';//默认截取第一秒第一帧$strlen=strlen($file);//exec("ffmpeg-i".$file."-y-fmjpeg-ss".$time."-t0.001-s320x240".$name."",$out,$status);$str="ffmpeg-i".$file."-y-fmjpeg-ss3-t".$time."-s320x240".$name;$result=system($str);}

Fmpeg读取视频信息

<?phpdefine('FFMPEG_PATH','/usr/local/ffmpeg2/bin/ffmpeg-i"%s"2>&1');functiongetVideoInfo($file){$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获得视频文件的总长度时间和创建时间

functiongetTime($file){$vtime=exec("ffmpeg-i".$file."2>&1|grep'Duration'|cut-d''-f4|seds/,//");//总长度$ctime=date("Y-m-dH:i:s",filectime($file));//创建时间//$duration=explode(":",$time);//$duration_in_seconds=$duration[0]*3600+$duration[1]*60+round($duration[2]);//转化为秒returnarray('vtime'=>$vtime,'ctime'=>$ctime);}

另外一种方法

ffprobe-vquiet-print_formatjson-show_format-show_streamstest.mp4
