• There is a video stream option and player. But can't find where to manage video and stream

  26 janvier 2018, par Chanaka De Silva

  I’m working on this repository. in this application, we can upload a video taken by a action camera or drone, and it uses GPS coordinates (lat,lang) and draw the path of the video in the map. And also we can play the video via the system too after upload.

  Bt the size of the video is too much high. So it take a lot of time to process video and also download and play when we host in a server. I wanted to reduce size. So I write this code.

  try {
  
  new ffmpeg('demo.mp4', function (err, video) {
  
      if (!err) {
  
          video
  
              .setVideoSize('50%', true, false)
  
              .setVideoFrameRate(30)
  
              .save('output.mp4', function (error, file) {
  
                  if (error) {
  
                      console.log("error : ", error);
  
                  }
  
                  if (!error)
  
                      console.log('Video file: ' + file);
  
              });
  
          console.log('The video is ready to be processed');
  
      } else {
  
          console.log('Error: ' + err);
  
      }
  
  });

  }

  But the issue is I can’t find where is the video coming from in this application. We need to pass like "demo.mp4" to my code as you can see. This is the index file if this application : https://github.com/chanakaDe/replay-lite/blob/master/frontend/index.html

  And this is the player file : https://github.com/chanakaDe/replay-lite/blob/master/frontend/player.js

  This is the file called api.js : https://github.com/chanakaDe/replay-lite/blob/master/frontend/api.js

  This file also has some video functions : https://github.com/chanakaDe/replay-lite/blob/master/gopro/index.js

  Please guys, sometimes you will see this questions as a silly question. But you have the repo to check and can you guys please check and let me know where to get a video file or stream to add my size reduce code ?

  How to fix that ?

• Promise chaining and resolution

  23 janvier 2019, par Shourya Sharma

  I am trying to convert videos one by one with the help of promises. i am using ffmpeg for conversion and multer for uploading multiple files.

  multer uploads multiple files at once after which i have to chain the conversions one by one. as of now it just converts the 1st file.

  i thought chaining of promises ..like in an array should work but i am confused if i can define new promises in an array as ffmpeg also returns a promise

  My router :

  const router = require('express').Router();
  
  const multer = require('multer');
  
  const ffmpeg = require('ffmpeg');
  
  
  
  let str;
  
  const storage = multer.diskStorage({
  
    destination: (req, file, cb) => {
  
      cb(null, './uploads');
  
    },
  
    filename: (req, file, cb) => {
  
      str = file.originalname.replace(/\.[^/.]+$/, "");
  
      str = str.replace(/[^a-z0-9+]+/gi, '_') + '.' + file.originalname.replace(/^.*\./, '');
  
      cb(null, str);
  
    }
  
  });
  
  
  
  const upload = multer({ storage: storage }).array('files', 12);
  
  
  
  router.post('/upload', (req, res, next) => {
  
    // req.files is an array of files
  
    // req.body will contain the text fields, if there were any
  
    function uploadFile() {
  
      return new Promise((resolve, reject) => {
  
        upload(req, res, (err) => {
  
          if (err) {
  
            res.send(err) // Pass errors to Express.
  
            reject(`Error: Something went wrong!`);
  
          } else if (req.files == undefined) {
  
            res.send(`No File selected.`);
  
            resolve();
  
          } else if (!err && req.files.length > 0) {
  
            res.status(201).send(`${req.files.length} File(s): ${req.files} uploaded successfully.`);
  
            console.log('uploaded');
  
            resolve();
  
          }
  
        });
  
      });
  
    }
  
  
  
    uploadFile().then(() => {
  
      try {
  
        var process = new ffmpeg('./uploads/' + str);
  
        process.then(function (video) {
  
          console.log('The video is ready to be processed');
