• ffmpeg convert one image to video

  11 mars 2019, par Zedd W

  At the moment I can convert image sequence to video. But the current requirement is to convert one image into a video. And can achieve some special effects.

  For example :

  1. fade in/out

  2. flash in/out

  3. pan top/bottom/left/right

  4. zoom in/out

• ffmpeg taking time to convert video

  2 septembre 2015, par sonam Sharma

  hello all i am having a video hosting site like youtube where i allow almost all kinds of videos to be uploaded but i would like to convert all the uploaded videos to mp4 format

  i can do this and my code is below

    require 'vendor/autoload.php';
  
          $getEXT_check=substr(@$_FILES['profileimage99']['name'],-3);
  
          if($getEXT_check !='mp4' || $getEXT_check !='MP4'){
  
          exec('ffmpeg -i '.$uploadfile.' -f mp4 -s 896x504 '.$new_flv.''); }
  
          //execute ffmpeg and create thumb
  
          exec('ffmpeg  -i '.$uploadfile.' -ss 00:00:28.435 -vframes 1  '.$new_image_path);
  
          $theduration=exec('ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 '.$uploadfile.' 2>&1');
  
          $theduration_val=round($theduration/60, 2);

  this code converts the non mp4 videos to mp4 and gets a thumbnail and gets duration correctly but the problem is that the process takes very much time like more than 2-3 hrs if i upload flv or mkv formats of about 100mbs.

  please suggest me something better please if you need to see the full page code

  Complete Code :

       <?php
  
      @session_start();
  
     include "conn.php";
  
      include "date.php";
  
     $sid = $_SESSION['id'];
  
     $ipIP=$_SERVER['REMOTE_ADDR'];
  
     $uploaddir = "members/$sid/video/";
  
  
  
       //Check the file is of correct format.  
  
        function checkfile($input){
  
        $ext = array('mpg', 'wma', 'mov', 'flv', 'mp4', 'avi', 'qt', 'wmv', 'rm', 'mkv', 'MP4','3gp');
  
        $extfile = substr($input['name'],-4);

      if($safe_file['safe'] == 1){
  
                  if (move_uploaded_file(@$_FILES['profileimage99']['tmp_name'], $uploadfile)) {
  
  
  
                  $base = basename($uploadfile, $safe_file['ext']);
  
                  $new_file = $base.'mp4';
  
                  $new_image = $base.'jpg';
  
                  $new_image_path = $live_img.$new_image;

      echo "<img src="http://stackoverflow.com/feeds/tag/mem/$sid/img/$new_image" class="The_Append_L_snap" style='max-width: 300px; max-height: 300px' />";die;
  
           } else {
  
                  echo "Possible file upload attack!\n";
  
                  print_r($_FILES);
  
           }
  
  
  
      }else{
  
  
  
           echo 'Invalid File Type Please Try Again. You file must be of type 
  
           .mpg, .wma, .mov, .flv, .mp4, .avi, .qt, .wmv, .rm'.$_FILES['profileimage99']['name'];
  
  
  
      }
  
    }else{
  
   echo 'Please choose a video';die;
  
    }
  
    ?>

  The issue :
  FFmpeg call above takes too much time to convert the video to MP4.

  Note :
  In the future I will be having a quality selector in my video.js player.
