• How can we reduce the size of audio file after uploading ?

  8 novembre 2019, par Arjun Pujari

  I have used this command in the terminal to install the package : composer require pbmedia/laravel-ffmpeg. The package is successfully downloaded, but I don’t know how to use it. I don’t even know if this package can also reduce the audio file size or not.

  Anyone know any other library or package ?

      
  
          <form action="{{route('upload')}}" method="post" enctype="multipart/form-data">
  
              Select Audio to upload:
  
              <input type="file" />
  
              <input type="submit" value="upload MP3" />
  
          </form>
  
      
  
  
  
  
  
  &lt;?php

  Here is my controller. Write basic code for save file :

  namespace App\Http\Controllers;
  
  
  
  use Illuminate\Http\Request;
  
  use Pbmedia\LaravelFFMpeg\FFMpeg;
  
  
  
  class FileCompress extends Controller
  
  {   
  
      public function compressFile(Request $request)
  
      {
  
            $uploadFileName = mt_rand().time(). '.' . $file->getClientOriginalExtension();
  
            $filetype = substr($file->getClientMimeType(), 0, strpos($file->getClientMimeType(), "/"));
  
  
  
          if($filetype == 'video'){
  
  
  
            $localpath =  public_path().'/videos/'.$uploadFileName;
  
           //code for video file compress.
  
          }else{
  
            //code for audio file compress.
  
          }
  
      }
  
  }

  But I need to reduce the audio file size when a file is uploaded or reduce the file size immediately after the file upload. How can i do that ?

• FFMPEG loses drop frame flag when converting from 29.97 mov to mp4

  18 décembre 2018, par dementis

  I’ve got a 29.97 drop frame video, proven with the mediainfo output lines framerate: 29.97 and Delay_DropFrame: Yes. I want to convert it to an mp4.

  Running ffmpeg -i INPUT.mov -y -b:v 1500k -vcodec libx264 -vf scale=640:-1 -pix_fmt yuv420p -movflags +faststart -strict -2 OUTPUT.mp4
  yields a non-drop frame video. When I run mediainfo against the new file, I can see that the framerate is still 29.97, but there is no indication of drop frame anymore.
  This also happens when i run the above outputting an mov, and also when i run ffmpeg -i INPUT.mov OUTPUT.mov, so i think it’s purely in the conversion where the data is being lost.

  One lead i’m following is that mediainfo outputs 3 sections for the original mov, [General], [Video], [Other], while my new mp4 only outputs [General] and [Video].

  My FFMPEG version is 3.4.1
  Any ideas ?
