• How to access uploaded file from multer ?

  13 avril 2017, par Somename

  Im able to upload an image to S3. Now, if the file selected is .gif, I want to be able to convert the .gif file to .mp4 and upload the converted file to S3. I am able to convert a .gif to .mp4 with ffmpeg only if I give the path of the file. How do I access the uploaded file from Multer ? Below is my code :

  var express = require('express');
  
  var bodyParser = require('body-parser');
  
  var app = express();
  
  var aws = require('aws-sdk');
  
  var multer = require('multer');
  
  var multerS3 = require('multer-s3');
  
  var s3 = new aws.S3();
  
  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  
  
  var upload = multer({
  
      storage: multerS3({
  
          s3: s3,
  
          bucket: 'myBucket',
  
          key: function (req, file, cb) {
  
              console.log(file);
  
              var extension = file.originalname.substring(file.originalname.lastIndexOf('.')+1).toLowerCase();
  
  
  
                  if(extension=="gif"){
  
                  console.log("Uploaded a .gif file");
  
  
  
                  ffmpeg(file) //THIS IS NOT WORKING
  
                      .setFfmpegPath("C:\\ffmpeg\\bin\\ffmpeg.exe")
  
                        .output('./outputs/2.mp4')    //TRYING TO UPLOAD LOCALLY, WHICH FAILS
  
                        .on('end', function() {
  
                          console.log('Finished processing');
  
                        })
  
                        .run();
  
              }
  
  
  
              cb(null, filename);
  
          }
  
      })
  
  });

  I’m trying to access the uploaded file like this : ffmpeg(file) since file is an argument passed in the multer function.

  My form :

  <form action="/upload" method="post" enctype="multipart/form-data">
  
      <input type="file" /> <br />
  
      <input type="submit" value="Upload" />
  
  </form>

  In which part of the process do I convert the file ?

  Please help. Many thanks.
