• 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 use FFMPEG -vframe in wordpress creates jpg then clean filename to have only single dot ?

  18 mars 2019, par Mr.AX

  What is the best way to output jpg file from video file using FFMPEG avoiding file name to contain double dots resulting file being treated as non existent ?

  My goal is to create a clean alternative solution to avoid making jpg extension file having double dots in its created filename, from its original video file (such as mp4). Below is the coding I’m currently using for video uploading via ffmpeg, creating an extra thumbnail file from its video file :

  // 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>';
  
  }

  One of the solution is to add and change

  $file_path_v = $file_path 
  
  echo str_replace('.', '_', $file_path_v);
  
  $file_path_thumb = pathinfo('$file_path_v.\".jpg\";')

  but how would I change the line that suppose to display its thumbnail at :

  echo '';

  I would like some pointers if anyone can have the cleanest solution to work around it ?
