• cannot find ffmpeg in videoshow in nodejs

  6 novembre 2019, par Sunil Garg

  I want to create video from image files. So I have installed videoshow module. And configured the same as per the documentaion.

  var videoOptions = {
  
    fps: 25,
  
    loop: 5, // seconds 
  
    transition: true,
  
    transitionDuration: 1, // seconds 
  
    videoBitrate: 1024,
  
    videoCodec: 'libx264',
  
    size: '640x?',
  
    audioBitrate: '128k',
  
    audioChannels: 2,
  
    format: 'mp4',
  
    pixelFormat: 'yuv420p'
  
  }
  
  
  
  var images = [
  
    "D:/PROJECTS/Video/storage/1.jpg",
  
    "D:/PROJECTS/Video/storage/2.jpg"
  
  ];
  
  
  
  app.get("/video", function () {
  
    videoshow(images, videoOptions)
  
      // .audio('song.mp3')
  
      .save('video.mp4')
  
      .on('start', function (command) {
  
        console.log('ffmpeg process started:', command)
  
      })
  
      .on('error', function (err, stdout, stderr) {
  
        console.error('Error:', err)
  
        console.error('ffmpeg stderr:', stderr)
  
      })
  
      .on('end', function (output) {
  
        console.error('Video created in:', output)
  
      })
  
  });

  But When I run it shows the error on server

  Error: Error: Cannot find ffmpeg

      at D:\PROJECTS\Video\node_modules\videoshow\node_modules\which\which.js:89:16

  Then I installed ffmpeg using

  npm install ffmpeg --save

  but not worked. So I tried installing at the global level using

  npm install ffmpeg -g

  Even installing on my window machine and setting the path of its bin folder in environment variables did not work ?

  What could be the issue ?

• 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 ?
