• NodeJs: Parsing POST request file upload as stream to ffmpeg

  29 May 2017, by Christian Abdelmassih

  I’m trying to upload a file by sending a POST request to my NodeJs-server where the server will upon receiving the request (but not necessarily whole file) create a readStream on the incoming file and pass it to fluent-ffmpeg for video-compression and then saving it on the server. The idea is to pass the stream to ffmpeg without waiting for the whole file to be uploaded instead of waiting for the upload to complete and then pass the file since it would take more time and require to store the file temporarily on the server before the compression.

  With the current code ffmpeg gives the error pipe:0: Invalid data found when processing input which I translate to some error with the stream creation. The code is as follows

  module.exports = function(req, res) {
  
    let formidable = require('formidable');
  
    let form = new formidable.IncomingForm();
  
    form.parse(req, (err, fields, files) => {
  
      let readStream = fs.createReadStream(files.uploadedfile.path);
  
      let ffmpeg = require('fluent-ffmpeg')
  
      let ffmpegCmd = ffmpeg(readStream)
  
      ...
  
    });
  
  });

  Am I making some wrong assumption here?

• Problems with slowing down when grid synthesis operation request via ffmpeg is received simultaneously

  7 November 2022, by bongcheol Kim
  

  1. Crop/scaling/volume leveling encoding of videos uploaded by users in S3 with predetermined settings

  


  2. Synthesize in grid form with other pre-prepared videos.

  


  


  Perform the above tasks through ffmpeg.
Encoding slows down when multiple requests occur simultaneously.
(Maybe it's because we shared the server's resources.)

  


  To process task requests from 1 and 2 at the same time, but to process them
What can I do?

  


  Is there a service on AWS that can solve my problems?

  


  I thought about creating and processing ec2 individually for each request, but is this possible?

  


  

  1. Invoke API

  


  2. Create EC2

  


  3. Proceed with one encoding operation on the corresponding EC2

  


  4. Delete EC2 after uploading s3
