• Simplest way to convert uploaded videos to mp4 before storing them on a server ?

  26 juin 2017, par ioan

  I’m using a goDaddy server and cPanel to make a website, and I want to make a feature that lets users upload videos, save them on the server, then display them elsewhere on the site.

  displaying uploaded videos :

  echo "<video controls="controls"><source src="{$video_row[$i]}"></source></video>";

  But I found out that most browsers can only play a few video formats like mp4. So I want to convert them all to mp4 before saving them to the server. So sometime before running the move_uploaded_file() function.

  Is there something I can download and put on the server that will let me do that ? From other questions I found about FFmpeg, but i couldn’t figure out how to use it and if I can even install it on a godaddy server.

  Php code :

  if (isset($_FILES["submit_file"])) { //this comes from an html form
  
      $name = $_FILES['submit_file']['name'];
  
      $original_name = $name;
  
      $size = $_FILES['submit_file']['size'];
  
      $tmp_name = $_FILES['submit_file']['tmp_name'];
  
      $target_dir = null;
  
  
  
      $finfo = finfo_open(FILEINFO_MIME_TYPE); //get mime type
  
      $mime = finfo_file($finfo, $tmp_name);
  
  
  
      if ($mime == "video/mp4" || $mime == "video/wmv" || $mime == "video/avi" || $mime == "video/mov") {
  
          if ($mime != "video/mp4") {
  
              //CONVERT TO MP4
  
          }
  
          $target_dir = "uploads/videos/";
  
          $path = $target_dir.basename($name);
  
  
  
          if (move_uploaded_file($tmp_name, $path) == true) {
  
              //moved
  
          }
  
      } else {
  
          //error: Unsupported File Type
  
      }
  
  }

  How do others deal with videos ? I was able to upload and play mp4 videos fine with my method, but html5 can’t seem to play other types, and I don’t want to limit users to only upload mp4

• Flash media server invalid mp4

  19 décembre 2012, par Ben Ford

  I have an MP4 file that was ripped from a DVD containing chapters using handbrake.
  I've then used ffmpeg to convert that rip into seperate mp4 files for dynamic streaming with Adobe's Flash Media Server.

  I have used exactly the same ffmpeg parameters before and had no problem. However this time, I get output from ffmpeg :

  max_analyze_duration reached

  The resulting files won't stream from FMS. There's no error in the FMS logs or web console.
  Are there any known reasons that FMS wouldn't stream files like this ?

  Or does anyone know of any other diagnostic tool to analyze what's going on within FMS ?

  Thanks
  Ben
