composer安装

composer require php-ffmpeg/php-ffmpeg

use FFMpegFFMpeg;

use FFMpegCoordinateTimeCode;

文件安装目录，PHP大概率无权访问，需修改php.ini

open_basedir=abc/:/tmp/:/proc/:/usr/local/bin/ffprobe:/usr/local/bin/ffmpeg

private function GetCoveImg($path = ''){

if($path == ''){

return;

}

$ffmpeg = FFMpeg::create(array(

//程序安装目录，不加可能会无法运行

'ffmpeg.binaries' => '/usr/local/bin/ffmpeg',

'ffprobe.binaries' => '/usr/local/bin/ffprobe'

));

$videoname = $path;//视频地址

$video = $ffmpeg->open($videoname);

$frame = $video->frame(TimeCode::fromSeconds(1));//获取第几帧

$filename = time().".jpg";//获取图片命名

$frame->save($filename);//获取图片

$dirname = date("Ymd");//设置日期文件夹

if (!is_dir("upload/video/img/$dirname")){//是否已有文件夹

mkdir("upload/video/img/$dirname");//没有则新建文件夹

}

copy($filename,"upload/video/img/$dirname/$filename"); //拷贝到新目录

$newpath = "upload/video/img/$dirname/$filename";

$url = $this->GetUrl();

return $url.'/'.$newpath;
