thinkphp6 使用FFMpeg获取视频信息

1.本地安装 FFMpeg，官网下载地址：https://ffmpeg.org/download.html#build-windows

 解压后，把文件夹放到自定义目录，添加系统变量

2.安装依赖,composer.json 添加

"php-ffmpeg/php-ffmpeg": "^0.19.0",

3.封装class类

<?php
namespace app\api\controller;

use FFMpeg\FFMpeg;
use think\facade\Config;
use FFMpeg\Coordinate\TimeCode;

/**
 * FFMpeg处理音视频
 */
class Media extends Common
{
    /**
     * 获取视频时长 单位：秒
     * @param string $oriPath
     * @return string
     */
    public function videoDuration(string $oriPath=''): string
    {
        $config = [
            'ffmpeg.binaries' => Config::get('app.app_ffmpeg'),
            'ffprobe.binaries' => Config::get('app.app_ffprobe')
        ];
        $ffmpeg = FFMpeg::create($config);
        $video = $ffmpeg->open($oriPath);

        $duration = $video->getStreams()->first()->get('duration');

        return bcdiv($duration,1,0);
    }

    /**
     * 获取视频封面图(视频第一帧)
     * @param string $oriPath
     * @return string

    public function videoCoverImage(string $oriPath=''): string
    {
        try {
            $config = [

            $res = $cos->uploadStaticFile($imgPath,'.'.$imgPath);
            if($res['msg']!='success'){
                return '';
            }
            unlink('.'.$imgPath);

            return $imgPath;
        }catch (\Exception $e){
            return '';
        }
    }

    /**

    public function getVideoInfo($file)

        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

        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;
    }
}

4.本地测试

 public function testVideo()
    {
        $path = base_path()."/test.mp4";
        $media = new Media();
//        $img_url = $media->videoCoverImage($path);
        $video_len = $media->videoDuration($path);
//        $videoInfo = $media->getVideoInfo($path);
        dump($video_len . '秒');
    }
