  I have trouble with ffmpeg. If I want to create a thumb from a video I get the following error-message :

  file_exists() : open_basedir restriction in effect. File(/tmp/frame59c41921d102f6.99590608.jpg) is not within the allowed path(s) : (/home/admin/web/faplink.net/public_html :/home/admin/tmp)

  Code :

  $video_thumb_path = "thumbs/" . md5($request->file("file")->getClientOriginalName() . time()) . ".png";
  
            $mov = new \ffmpeg_movie(storage_path("app/public/") . $post->media);
  
            $frame = $mov->getFrame(10);
  
            if ($frame) {
  
                $gd_image = $frame->toGDImage();
  
                if ($gd_image) {
  
                    imagepng($gd_image, $video_thumb_path);
  
                    imagedestroy($gd_image);
  
                    $post->thumb = $video_thumb_path;
  
                }
  
            }
  
            break;

• FFmpeg - Partial fade effect on overlay image

  22 octobre 2023, par antoox

  I'm having trouble with ffmpeg.

  


  I want to make a 3-second video (example here : https://streamable.com/7uhi7f) with :

  


  

  • A background image (300x350 jpeg file)

  


  • A logo overlaid in the center of the background image (100x40 png file)

  


  • And I would like the logo to fade in and out with the following opacity timeline :

  


  


  

  1. At 0 seconds, the opacity is 0.5

  


  2. At 1 second, the opacity is 1

  


  3. At 2 seconds, the opacity is 0.2

  


  4. At 3 seconds, the opacity is 1.

  


  


  So far I only succeeded in adding an overlay with a fully fade IN (between 0 to 1s) and a fully fade OUT (from 2s to 3s) :

  


  ffmpeg -loop 1 -i background.jpeg -framerate 30 -loop 1 -i logo.png -filter_complex "[0]format=rgba,scale=300:250[o];[1]format=rgba,fade=in:st=0:d=1:alpha=1,fade=out:st=2:d=1:alpha=1[i];[o][i]overlay=x=(W-w)/2:(H-h)/2" -c:v libx264 -t 3 output.mp4

  


  I also tried geq & blend filters without any success.

  


  What would be the more appropriate approach to handle that kind of effect ?
