thinkphp6 使用FFMpeg獲取影片資訊

渺小的人类發表於2024-07-03
PHP

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
 */
class Media extends Common
{
    /**
     * 獲取影片時長 單位：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);
    }

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

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

        $data = array();

        }
        if (isset($data['seconds']) && isset($data['start'])) {
            $data['play_time'] = $data['seconds'] + $data['start']; //實際播放時間
        }
        $data['size'] = filesize($file); //檔案大小
        return $data;
    }
}

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');
    }

獲取影片時長：
