  i am submiting this form

   <form style="margin:0px;display:none;" action="videoupload.php" method="post">
  
              <input type="file" style="display:none;" />
  
              </form>

  to the page above
  when ever i submit the form i get the error no file added like as if the post variable is not getting there on the page and when i remove the validation

    if(!isset($_POST['profileimage99']) || $_FILES["profileimage99"]["size"] ==''){
  
  echo 'No file added';die;
  
   }

  i can upload some files usually less then 2 mb file but for larger files i get undefined index error for profileimage99.

  i have increased the upload_max_size from php.ini file

  Please not that the form is submitted by ajax call

• ffmpeg .mkv -> .mp4 mux & merge all audio tracks

  21 juin 2017, par Milo

  I’d like to losslessly convert an mkv to mp4, but take all existing audio tracks from the mkv (typically 2) and actually merge the audios into 1 track. Is ffmpeg a good tool for this ? I believe it has all the functionality I need, but what would be the command for that then ?
