• Changing/Replace 1st dot in every generated jpg filename from video to remain single dot

  23 mars 2019, par Mr.AX

  my site is using ffmpeg to generate a thumbnail jpg for every video being uploaded. The code as below :

  // get the videos uploaded
  
  foreach ($videos as $video) {
  
      if ($profile_author_id == $userid || current_user_can('level_10')) {
  
          $imagebuttons = '<span class="edit-buttons"><span class="icon button-delete icon-cancel rad3"></span></span>';
  
      }
  
  
  
      echo '<div class="profile-video-thumb-wrapper"><div class="profile-img-thumb profile-video-thumb rad3" style="background: url('.$video->guid.'.jpg) center no-repeat; background-size: cover;">';
  
      echo    $imagebuttons;
  
  
  
      if(get_post_meta($video->ID, 'processing', true) &amp;&amp; !is_video_processing_running(get_post_meta($video->ID, 'processing', true))) {
  
          delete_post_meta($video->ID, 'processing');
  
          unlink(get_post_meta($video->ID, "original_file", true));
  
          delete_post_meta($video->ID, 'original_file');
  
  
  
      }
  
      $file_path = get_attached_file($video->ID);
  
      $file_path_thumb = $file_path.".jpg";
  
      if(!file_exists($file_path_thumb)) {
  
          $output = shell_exec("/usr/local/bin/ffmpeg -i $file_path");
  
          $videoresizeheight = get_option("videoresizeheight") ? get_option("videoresizeheight") : '400';
  
          $comd = "/usr/local/bin/ffmpeg -y -i \"$file_path\" -f mjpeg -vframes 1 -ss 00:00:03.000 -vf scale=".$videoresizeheight.":-1 \"$file_path_thumb\" 2>&amp;1";
  
          shell_exec($comd);
  
      }
  
  
  
      if(get_post_meta($video->ID, 'processing', true)) {
  
          if ($profile_author_id == $userid || current_user_can('level_10')) {
  
              echo '<span class="video-processing rad3">'._d('this video is still processing',1269).'</span>';
  
              echo '<img data-original-url="'.get_template_directory_uri().'/i/video-placeholder.svg" class="mobile-ready-img rad3" alt="'.get_the_title().'" data-responsive-img-url="'.get_template_directory_uri().'/i/video-placeholder-mobile.svg" style='max-width: 300px; max-height: 300px' />';
  
          }
  
      } else {
  
          echo '<div></div>([^a-zA-Z0-9])/", "", $video->post_title).'" class="video-player-lightbox text-center hide" itemprop="video" itemscope itemtype="http://schema.org/VideoObject">';
  
          echo    '';
  
          echo    '';
  
          echo    '<video height="100%" width="100%" controls="controls">';
  
          echo        '<source src="'.$video->guid.'" type="video/mp4">';
  
          echo        _d("Your browser does not support the video tag.",1270);
  
          echo    '</source></video> ';
  
          echo '</div>';
  
  
  
          echo '<a href="#'.preg_replace("></a>([^a-zA-Z0-9])/", "", $video->post_title).'" rel="profile-video">';
  
          echo    '<img src="http://stackoverflow.com/feeds/tag/src" style='max-width: 300px; max-height: 300px' />"'.$video->guid.'.jpg" class="hide" />';
  
          echo    '<img src="http://stackoverflow.com/feeds/tag/&#039;.get_template_directory_uri().&#039;/i/video-placeholder.svg" class="video-image-play" style='max-width: 300px; max-height: 300px' />';
  
          echo '';
  
      }
  
  
  
      echo '<div class="clear"></div></div>'."\n";
  
  }
  
  if(count($videos) > 0) {
  
      echo '<div class="clear10"></div>';
  
  }

  This as a result generates a thumbnail jpg file for every video uploaded ; but the problem occurs when the filename of jpg includes a dot brought forward from the original video file, example I upload a video with filename video.mp4, this will generate a jpg file call video.mp4.jpg. And this, my website will treat this file as none existence.

  Now I need to find a solution that can generate the correct thumbnail filename while still sticking to use wordpress tags, which is changing the .mp4 to -mp4 when adding an additional .jpg extention.

• How to include audio in an overlay ffmpeg command ?

  27 avril 2021, par gilad s

  Using ffmpeg I add a video overlay successfully over an origin video (origin has audio, overlay doesn't). However the audio of the origin video doesn't appear in the result video.

  


    ffmpeg  -i source.mp4 -i overlay.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, scale=1280x720[top]; 
  [1:v]setpts=PTS-STARTPTS, scale=1280x720, format=yuva420p, 
  colorchannelmixer=aa=0.2[bottom]; [top][bottom]overlay=shortest=1" 
  -shortest -acodec copy -vcodec libx264 result1.mp4


  


  Even if I execute the following separate command on the result of the previous command - still no audio appears in the new result video.

  


    ffmpeg -i result1.mp4 -i audio.mp3 -c:v copy -c:a aac result2.mp4


  


  Here is the log :
