• writeImages and renaming the images using PHP

  3 mai 2015, par Kiran Kumar Dash

  I am working on a multimedia project. So, I am having a case where I am producing a sequence of images from a string input using he code below :

  <?php
  
  
  
      /*** a new Imagick object ***/ 
  
      $aniGif = new Imagick();
  
  
  
      /*** set the image format to gif ***/
  
      $aniGif->setFormat( "gif" );
  
  
  
      /*** a new ImagickPixel object for the colors ***/
  
      $color = new ImagickPixel( "white" );
  
  
  
      /*** set color to white ***/
  
      $color->setColor( "white" );
  
  
  
      $colorarray =array("white", "red", "blue" , "aqua", "fuchsia", "gray", "lime", "maroon", "navy", "orange", "purple", "silver", "teal", "yellow",  "green", "maroon", "green", "olive");
  
  
  
      /*** the text for the image ***/
  
      $string = "Hello Kiran Kumar";
  
  
  
  
  
      /*** a new draw object ***/
  
      $draw = new ImagickDraw();
  
  
  
      /*** set the draw font to helvetica ***/
  
      $draw->setFont( "./SociaLAnimaL.ttf" );
  
  
  
      /*** set the draw font to helvetica ***/
  
      $draw->setFontSize( "100" );
  
  
  
      /*** loop over the text ***/
  
      for ( $i = 0; $i <= strlen( $string ); $i++ )
  
      {
  
          /*** grab a character ***/
  
          $part = substr( $string, 0, $i );
  
  
  
          /*** a new ImagickPixel object for the colors ***/
  
          $color = new ImagickPixel( "white" );
  
  
  
          /*Generate random number for random color*/
  
          $randomNumber = rand(0,16);
  
  
  
          /*** create a new gif frame ***/
  
          $aniGif->newImage( 1920, 1200, $colorarray[$randomNumber] );
  
  
  
          /*** add the character to the image ***/
  
          $aniGif->annotateImage( $draw, 960, 600, 0, $part );
  
  
  
          /*** set the frame delay to 30 ***/
  
          $aniGif->setImageDelay( 30 );
  
  
  
      }
  
       /*** write the file ***/
  
          $aniGif->writeImages($directory.'kiran.jpg', $out);
  
  
  
  
  
  
  
  
  
      echo 'all done';
  
  
  
  ?>

  Now the problem is the writeimages object is generating images as kiran-0.jpg, kiran-1.jpg, kiran-2.jpg and so on. but what I am expecting is kiran001.jpg, kiran002.jpg, kiran003.jpg...and so on so that I can create a video out of it in while maintaining the sequence.Here is the code for video creation :

  <?php
  
  $ffmpeg= "/home/kiran/bin/ffmpeg";
  
      echo exec("$ffmpeg -f image2 -framerate 2/1 -pattern_type glob -i \"/var/www/html/fftest/getthumbnail/tmp/animate/est/*.jpg\" -i \"/var/www/html/fftest/getthumbnail/audios/audio1.mp3\" -c:v libx264 -c:a copy -shortest  -s 1920x1080 -r 60 -vf \"format=yuv420p\" \"/var/www/html/fftest/getthumbnail/output/animatedaudiocolor21.avi\" 2>&1" , $output, $return);
  
  ?>

  As you can see I am using -pattern type glob to select all the images, but this is getting confused with he naming sequence of kiran-0, kiran-1.

  So, what I am expecting here is how can I use writeimage object o name my images as the way mentioned above. so that I can use kiran%03d.jpg in my ffmpeg command instead of *.jpg.

  Or if any one can help me providing a code so that I can rename all the images in the expected manner.I tried the below code to rename all images :

  <?php
  
  $fileFolder="/fftest/getthumbnail/tmp/animate/test";
  
  $directory = $_SERVER['DOCUMENT_ROOT'].$fileFolder.'/';
  
  
  
  $i = 001; 
  
  $handler = opendir($directory);
  
  while ($file = readdir($handler)) {
  
      if ($file != "." && $file != "..") {
  
          $newName = 'kiran'.$i ;
  
          rename($directory.$file, $directory.$newName); // here; prepended a $directory
  
          $i++;
  
      }
  
  }
  
  closedir($handler);
  
  
  
  ?>

  But the code is unable to rename the images in sequence.

  Help please...

• PHP Foreach query only displays final result for slideshow ?

  22 janvier 2023, par ShaneRibz

  Using a query I pull the most liked video's on a localhosted stream webpage, and use FFMPEG to create a thumbnail if one isnt already existing and the video length.

  


  The query succesfully pulls the 4 most liked video's and displays them in a carousel. FFMPEG succesfully creates each thumbnail, and gets the length of each video.

  


  Somewhere, for whatever reason I cant figure out, only the final slide in the carousel displays the thumbnail as its background.

  


  Sorry if my code is messy, I'm learning how to better optimize.

  


  &lt;?php&#xA;                $sql = "use info";&#xA;                $pdo->exec($sql);&#xA;                $stmt = $pdo->query("SELECT * FROM `files` ORDER BY `like` DESC LIMIT 4");&#xA;                $filelist = $stmt->fetchAll(PDO::FETCH_ASSOC);&#xA;                    $h = 0;&#xA;                  foreach ($filelist as $row) {&#xA;                        if ($h &lt; 25){&#xA;                        $h&#x2B;&#x2B;;&#xA;                &#xA;                            $name = $row[&#x27;name&#x27;];&#xA;                            $location = $row[&#x27;location&#x27;];&#xA;                            $type = $row[&#x27;type&#x27;];&#xA;                            $uploadby = $row[&#x27;uploadby&#x27;];&#xA;                            $like = $row[&#x27;like&#x27;];&#xA;                            $id = $row[&#x27;fileid&#x27;];&#xA;                            $cat1 = $row[&#x27;Cat1&#x27;];&#xA;                            $cat2 = $row[&#x27;Cat2&#x27;];&#xA;            &#xA;                $ffmpeg = &#x27;F:\\xampp\ffmpeg.exe&#x27;;  &#xA;                $location = str_replace("/","\\", $location);&#xA;                $video = &#x27;F:\xampp\htdocs\\&#x27;. $location;  &#xA;                $bigloc = "F:\\xampp\htdocs\\thumb\big";&#xA;                $smallloc = "F:\\xampp\htdocs\\thumb\small";&#xA;                $image = $bigloc .

  When inspecting the source code on my web browser ;
"style="<?php echo 'background-image:url('. $image.');';?>"", this will only appear on the final slide. The first 3 slides wont have "background-image" at all.

  


  I feel as though I'm making a silly mistake and just cant see it.

  


  EDIT
I should note, the "$name" and "$time" for each displays properly, its just the background-image that does not.

  


  EDIT 2
Here is the source code :

  


  <div class="single-hero-slider-wrap single-animation-wrap slider-height-hm4 bg-image-hm4 slider-bg-color-black d-flex align-items-center slider-bg-position-1 bg-black" style="background-image: url(&amp;#x27;thumb/big/Alita Battle Angel.png&amp;#x27;);">&#xA;</div>

  


  The "background-image" shows in source, but during inspect element it does not. No errors populate either.

  


• How to create a random video from a random picture annd random audio file

  20 août 2019, par Francesco Milizia

  I am working on a batch conversion process where I need to add a random picture (a .jpg) on a random .mp3 and make an .mp4.

  This is the code I am using in terminal Mac OS X putting all the .mp3 and the .jpg in the same folder :

  for f in *.mp3; do /usr/local/Cellar/ffmpeg/4.1_1/bin/ffmpeg -r 1 -loop 1 -i abc5.jpg  -i "$f" -c:a copy -c:v libx264 -vf scale=1280:720 -shortest "${f%mp3}mp4"; done

  It works great, but I don’t know how to add another random feature for the .jpg files, so every time I have to put a different .jpg and change the name (usually in the file not in the script). I also know this must be something with for ((..., but I don’t know how to add it properly.

  for f in *.mp3; do /usr/local/Cellar/ffmpeg/4.1_1/bin/ffmpeg -r 1 -loop 1 -i abc5.jpg  -i "$f" -c:a copy -c:v libx264 -vf scale=1280:720 -shortest "${f%mp3}mp4"; done
