• How do I use ffmpeg in my renderer process in electron ?

  16 juillet 2023, par Infinibyte

  I'm trying to use ffmpeg in my renderer process in my electron app. I expose the modules in my preload.js file like this :

  


  const { contextBridge, ipcRenderer } = require('electron');
const ffmpegStatic = require('ffmpeg-static');
const ffmpeg = require('fluent-ffmpeg');
// make ffmpeg available as a function in the renderer process
contextBridge.exposeInMainWorld('ffmpeg', () => ffmpeg(ffmpegStatic.path));


  


  And I try to acces it in my renderer.js file like this :

  


  video.addEventListener('change', (event) => {
    const file = event.target.files[0];
    const filePath = file.path;
    const fileName = file.name;
    const fileExt = fileName.split('.').pop();
    const newFileName = fileName.replace(fileExt, 'mp4');
    const newFilePath = filePath.replace(fileName, newFileName);

    // Run FFmpeg
    ffmpeg()

        // Input file
        .input(filePath)

        // Audio bit rate
        .outputOptions('-ab', '192k')

        // Output file
        .saveToFile(newFilePath)

        // Log the percentage of work completed
        .on('progress', (progress) => {
            if (progress.percent) {
                console.log(`Processing: ${Math.floor(progress.percent)}% done`);
            }
        })

        // The callback that is run when FFmpeg is finished
        .on('end', () => {
            console.log('FFmpeg has finished.');
        })

        // The callback that is run when FFmpeg encountered an error
        .on('error', (error) => {
            console.error(error);
        });
});


  


  But then I get following error in the console : Uncaught TypeError : ffmpeg(...).input is not a function at HTMLInputElement.
I really don't know how to fix this, can anyone help me ?

  


  I tried writing it differently and defining ffmpeg in my rendere.js but nothing worked...

  


• PHP - Upload video convert mp4 and upload to Amazon S3

  31 octobre 2019, par Kadir Geçit

  I’m using amazon s3 as video storage for my website. I’m having problems for some videos. black screen or sound problems etc.

  I want to convert the video to mp4 format after uploading the video to my server and then upload it to amazon. Is it possible with FFMPEG ?

  I’m using this code for uploading files now :

  $file1 = $_FILES['file']['name'];
  
  $videoFileType = strtolower(pathinfo($file1,PATHINFO_EXTENSION));
  
  $file_name = sprintf('%s_%s', uniqid(),uniqid().".".$videoFileType);
  
  $temp_file_location = $_FILES["file"]["tmp_name"];
  
  
  
  require 'application/libraries/Amazon/aws-autoloader.php';
  
          $s3 = new Aws\S3\S3Client([
  
              'region'  => $amazon_region,
  
              'version' => 'latest',
  
              'credentials' => [
  
              'key'    => $amazon_key,
  
              'secret' => $amazon_secret,
  
              ]
  
          ]);     
  
  
  
          $result = $s3->putObject([
  
              'Bucket' => $amazon_bucket,
  
              'Key'    => $file_name,
  
              'SourceFile' => $temp_file_location,
  
              'ACL'    => 'public-read',
  
              'CacheControl' => 'max-age=3153600',
  
          ]);
  
              $filepath = $result['ObjectURL'] . PHP_EOL;
  
  
  
              echo json_encode([
  
                  'status' => 'ok',
  
                  'path' => $filepath
  
  
  
              ]);
