thinkphp6 使用FFMpeg獲取影片資訊

1.本地安裝 FFMpeg，官網下載地址：https://ffmpeg.org/download.html#build-windows

解壓後，把資料夾放到自定義目錄，新增系統變數

2.安裝依賴,composer.json 新增

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

3.封裝class類

<?php
namespace app\api\controller;

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

/**
 * FFMpeg處理音影片
 */

4.本地測試

 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');
    }
