• php ming flash slideshow to mp4/avi

  19 août 2013, par Stefan

  After hours of searching and trying i finally got a nice script together that generates a good looking Flash .swf file with a nice transaction in between de images.
  It works great if you access the swf file directly in a browser, depending on the amount of images the flash created takes anywhere between 10 and 60 seconds.
  But when uploading to Youtube the movie created flashed by in one second.
  Because swf isnt really a accepted fileformat for Youtube we decided to convert the flash file to mp4 or avi using ffmpeg.
  Unfortunally that didnt work, it had the same effect as the youtube movie.
  We had a old version of ffmpeg and updated that to a recent version and tried to convert again with the same result.
  The main thing i see is that ffmpeg cant see the swf file duration and bitrate, they are both 'N/A' while were do set them in the php script.

  Now i have to admit i havent really tested with the new version because the commandline options are a little different but ill work on that after i post this.
  In the previous version we tried setting the framerate of the source swf file, but that didnt work either.

  Anyone here that can has a idea ? it would be greatly appriciated.

  PHP Ming Script :

        $fps = 30;
  
           foreach($objects as $objectId => $images){
  
                  // START FLASH MOVIE
  
                  $m = new SWFMovie();
  
                  $m->setDimension($width, $height);
  
                  $m->setBackground(0, 0, 0);
  
                  $m->setRate($fps);
  
                  $m->setFrames(count($images)*202); //count(images)* 2 breaks *($fps*$breakTime)+22(fadeOut))
  
  
  
                  $i = 0;
  
                  foreach($images as $image){
  
  
  
                      // REMOVE THE BACKGROUND IMAGE
  
                      if($behind){
  
                          $m->remove($behind);
  
                      }
  
                      // # REMOVE
  
  
  
                      // LOAD NEW IMAGE
  
                      $img = new SWFBitmap(fopen($image,"rb"));
  
                      $pic = $m->add($img);
  
                      $pic->setdepth(3);

                      for($j=1;$j<=($fps*$breakTime);$j++){
  
                          $m->nextFrame();
  
                      }
  
                      $m->remove($pic);
  
                      // # BREAK
  
  
  
                      // LOAD THE NEXT IMAGE AS BACKGROUND, IF LAST IMAGE, LOAD FIRST
  
                      $nextBackgrondImage =($images[$i+1]) ? $images[$i+1] : $images[0] ;
  
                      $img = new SWFBitmap(fopen($nextBackgrondImage,"rb"));
  
                      $behind = $m->add($img);
  
                      $behind->setdepth(2);
  
                      // # LOAD
  
  
  
                      // AND FADE OUT AGAIN
  
                      $img = fadeOut($image, $width, $height);
  
                      $pic = $m->add($img);
  
                      $pic->setdepth(3);
  
                      // # FADE OUT
  
  
  
                      // BREAK TIME
  
                      for($j=1;$j<=($fps*$breakTime);$j++){

                      # BREAK
  
                      $i++;
  
                  }

  the final file is a 1 second video ( it doesn’t make any different how long is the video , all of them become a 1 second video )

  What is the problem ?
  this is the ffmpeg code that convert the video :

  echo passthru("$ffmpegpath -i uploads/$file -ar 22050 -ab 32 -f flv -s 320×240 uploads/aaa.flv 2>&1");

  Thanks
