node js fluent-ffmpeg 創建縮略圖

Question

currently im working on some video uploads, so i wanted to create a thumbnail during upload of videos.. I installated fluent-ffmpeg package but on first run i got error Error: cannnot find ffprobe then i changed ffmpeg to ffmpeg.ffprobe then i got undefined.on .. 這是我的視頻上傳完整代碼：

const multer = require('multer');
const uuid = require('uuid/v1');
const ffmpeg = require('fluent-ffmpeg');


const MIME_TYPE_MAP = {
  'video/MPEG-4': 'MPEG-4',
  'video/mpeg-4': 'mpeg-4',
  'video/mp4': 'mp4',
  'video/MP4': 'MP4'
};

const videoUpload = multer({
  limits: 10000000,
  storage: multer.diskStorage({
    destination: (req, file, cb) => {
      cb(null, 'uploads/videos');
    },
    filename: (req, file, cb) => {
      const ext = MIME_TYPE_MAP[file.mimetype];
      const currentfilename = uuid() + '.' + ext;
      cb(null, currentfilename);

      
      ffmpeg.ffprobe(`uploads/videos/${currentfilename}`)
      .on('end', function() {
        console.log('Screenshots taken');
      })
      .on('error', function(err) {
        console.error(err);
      })
      .screenshots({
        count: 1,
        folder: 'uploads/videos/thumb',
        filename: uuid() + '_screenshot.' + ext
      });
    }
  }),
  fileFilter: (req, file, cb) => {
    const isValid = !!MIME_TYPE_MAP[file.mimetype];
    let error = isValid ? null : new Error('Invalid mime type!');
    cb(error, isValid);
  }

});

module.exports = videoUpload;

看到的事情是fluent-ffmpeg為您提供了與ffprobe and ffmpeg一起使用的功能，它沒有為您提供它們（因此您必須手動安裝它們）。 其他方法是再安裝 2 個庫@ffmpeg-installer/ffmpeg和@ffprobe-installer/ffprobe並將路徑傳遞到fluent.ffmpeg 。 這里
