  Hi i am using FFMpeg below command1 for splitting video files in android,I am facing problem here when i upload more than 40Mb file taking too long time for splitting the files

  Using command2 videos are splitting very fastly but splitting files size count more than main file size

  Command1 :-

          String[] cmd = {"-ss", "" + "0", "-y", "-i", "inputFile", "-t", "" + "5", "-s",
  
                  "width" + "x" +
  
                          "height", "-vcodec", "mpeg4", "-b:v",
  
                  "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", Environment.getExternalStorageDirectory() +
  
                  "/FFMpeg" + "/" + outPutFile + "" + indexValue + "" + "." + "mp4"};

• How to join two videos into one stream using ffmpeg

  12 janvier 2016, par Andrey Prokhorenko

  I am new to ffmpeg, and I try to join two videos and get a video stream. I found a command :

  ffmpeg -i input0.avi -vf "movie=input1.avi [in1]; [in]pad=640*2:352[in0]; [in0][in1] overlay=640:0 [out]" out.avi

  but at the end we get a file "out.avi" and I need a video stream. Is there any way to achieve this ?

• 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
