• ffmpeg Fade-in stuck at first frame

  14 janvier 2017, par Pradeep Varadharajan

  I am trying to apply a fade-in effect at the start of a video and a fade-out effect at the end of a video.

  The fade-out effect works as I expect. However the fade-in doesn’t. I am noticing that at the starting, when the video is supposed to be black before fading in, the initial frame shows up vaguely and is stuck till the fade duration ends. The Audio fade-in seems to work correctly however.

  ffmpeg -i infile.mp4 -strict experimental -y -vf "fade=t=out:st=28:d=2, fade=t=in:st=2:d=2" -af "afade=t=out:st=28:d=2, afade=t=in:st=2:d=2" fade_in.mp4

  Can someone please help me understand what I am doing wrong here ?

  According to ffmpeg documentation for this filter, the below example is supposed to make the first 5.5 seconds black, then fade in for 0.5 seconds :

  fade=t=in:st=5.5:d=0.5

• 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 ?
