• Evolution #3928 : les emails sont publics dans le privé

  30 mars 2017, par nico d_

  Je suis assez d’accord avec jluc.
  Il faudrait donc considérer donc ça comme une évolution, et simplement supprimer l’affichage de l’email dans le privé.
  Ou peut être afficher juste la première et dernière lettre du nom et du domaine ?

  Quant à savoir si ça doit être configurable, je ne pense pas.
  Est ce que quelqu’un peut être gêné si cette fonctionnalité anomalie historique disparait ?

• FFmpeg.wasm demuxing - Get encodedChunks in Javascript

  16 mars 2023, par Kevin Baving

  I am building a video editor whose process looks like this :

  


  Demuxing -> Decoding -> Editing -> Encoding -> Muxing.

  


  The demuxing and muxing process is currently done with mp4box.js. I would like to replace mp4box.js with ffmpeg.wasm. Unfortunately, I can't get along with the process.

  


  What should FFmpeg.wasm do in the demuxing process ?

  


  

  • load a .mp4 file

  


  • extract the encodedVideoChunks and store them as EncodedVideoChunk objects in an array

  


  • extract the encodedAudioChunks and store them as EncodedAudioChunk objects in an array

  


  • get some metadata like : duration, timescale, fps, track_width, track_height, codec, audio_channel_count, sample_rate ....

  


  


  public async loadFile(file: File) {
    let data = await fetchFile(file)
    let blob = new Blob();
    await this.ffmpeg.setProgress(({ratio }) => console.log(`Extracting frames: ${Math.round(ratio * 100)}%`));
    this.ffmpeg.FS('writeFile', 'videoTest.mp4', data);
    //Here is where I am struggling
    //Should look like this: 
    //const command = '-i videoTest.mp4 -c:v copy .... '
    //await this.ffmpeg.run(command);
    //....
}


  


  Lets get deeper into my problem :

  


  Because FFmpeg.wasm is still a cli tool, I have no idea what the best way to safe the encodedChunks into a file is (and what kind of filetype I should use). Further I would like to know how to read that file propertly so that i can safe the input of the file into seperate EncodedVideo- and AudioChunks.

  


• ffmpeg is not working while uploading file using uploadify

  21 janvier 2016, par Ranjith

  for a particular video i tried like this, and it worked

  exec('/usr/bin/ffmpeg -i /home/xxxxxx/public_html/test/video1.mp4  /home/xxxxxxx/public_html/test/video1.flv');

  but for uploadify i write code like this ,

  <?php
  
  
  
  if (!empty($_FILES)) {
  
  $userId=$_SESSION["user_userid"];
  
  $filename = $_FILES['Filedata']['name'];
  
  $filetmpname = $_FILES['Filedata']['tmp_name'];
  
  $fileType = $_FILES["Filedata"]["type"];
  
  $fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1024);
  
  $folder=$_REQUEST['folder'];
  
  
  
  exec("/usr/bin/ffmpeg -i"."/home/xxxxxx/public_html/private/".$folder."/".$filename." "."/home/xxxxxx/public_html/private/".$folder."/".$filename.".flv");
  
  
  
  }elseif($_POST['d']){
  
  $filename = $_POST['d'];
  
  $folder=$_REQUEST['folder'];
  
  $dFile = $folder.$filename;
  
  if(file_exists($dFile)){
  
      unlink($dFile);
  
  }
  
  }
  
  ?>

  this code is not converting the uploaded file.
  help me please.

  thanks
