• String is showing undefined

  30 octobre 2022, par Lol

  I am trying to create video using ffmpeg and returning its path to index.js but path is showing undefined.

  


  index.js

  


  app.get('/content/:myfact', async (req, res) => {
  let myfactdata = req.params.myfact;
  let myfact = myfactdata.replace("_", " ");
  const video = await generateVideo(myfact);
  console.log(video)
});


  


  This is my contentVideo.js

  


  const generateImage = require('./contentimage.js');
const { spawn } = require('child_process');

const generateVideo = async (myfact) => {
  await generateImage(myfact);
  const child = spawn('ffmpeg', [
    '-i', 'pictures/download/image.png', 'pictures/download/video.mp4'
  ]);
  child.on('close', function (code, signal) {
    const video = 'pictures/download/video.mp4'
    return video
  });
}

module.exports = generateVideo


  


• How can I change an animation into .mp4 video in android ?

  15 août 2016, par littlebird

  Here is the problem. First I have some pictures and I have built an animation in ImageView so that pictures can fade in and fade out, with rotating, scaling...
  Question is how to save it (or how to change this animation into .mp4 or other format). I have searched this problem in SO, some say using ffmpeg, or javaCV, or jcodec. But all these way save images to video one frame by one frame, I don’t understand how to completely save the rotating, scaling during each fading in and fading out. Or is there any way else to do so ?
  Thanks in advance.

• Converting a video and capturing a thumbnail through ffmpeg-php

  14 mai 2014, par HackerManiac

  Can anyone give a code on how do i upload and covert a video using ffmpeg.

  As thought currently i have only uploading system.

  vu.php

  define('UPLOAD','../../videos/');
  
      $fileName = time().$file['name']; 
  
      $target = UPLOAD.$fileName;
  
  
  
    if(move_uploaded_file($file['tmp_name'],$target)){                
  
        exec("ffmpeg -i ".UPLOAD." ".UPLOAD.$filename.".flv"); 
  
    }

  This pice of code block just uploads the video on video folder but does not converts it to .flv.
  I am not sure how to use ffmpeg.

  My diretory looks like this

  www[localhost]->videos[videos folder]
  
  www[localhost]->pictures[pictures folder]
  
  www[localhost]->resources[folder]->php[folder]->vu.php

  I also want to return a .jpg image of any frame of video through json by converting via ffmpeg and uploading it to pictures folder.

  return json_encode(array("thumbnail"=>$image_src));
