Convert video to MP4 with php

Question

here is my problem : On my website I want to allow users to upload any type of video. But with the HTML5 tag only .mp4 video can be used. So I want to convert any type of video submit by the user to MP4 then add the path to the databse.

I've read something about FFmpeg but I can't figure out how to use it. I tried to use shell_exec("ffmpeg -i ".$vid." -vcodec libx264 -crf 20 out.mp4 2>&1") without success.

The html

<form method="post" enctype="multipart/form-data" name="form" action="post.php">
			
																					
	<input type="file" name="media-vid"  class=" file_multi_video" accept="video/*">
														
</form>

The php script:

if(file_exists($_FILES['media-vid']['tmp_name']) && is_uploaded_file($_FILES['media-vid']['tmp_name']))
	{
		
		
		
		$targetvid = md5(time());
		$target_dirvid = "videos/";
		$target_filevid =  $targetvid.basename($_FILES["media-vid"]["name"]);
		$uploadOk = 1;
		$videotype = pathinfo($target_filevid,PATHINFO_EXTENSION);
	
		
			
		if ($_FILES["media-vid"]["size"] > 500000000) {
		$uploadOk = 0;
		echo "Sorry, your file is too large.";
		}
	
	// Check if $uploadOk is set to 0 by an error
	if ($uploadOk == 0) {
		echo "Sorry, your video was not uploaded."; 
	// if everything is ok, try to upload file
		} else {
		
		 $target_filevid = strtr($target_filevid, 
			  'ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðòóôõöùúûüýÿ', 
			  'AAAAAACEEEEIIIIOOOOOUUUUYaaaaaaceeeeiiiioooooouuuuyy');
		 $target_filevid = preg_replace('/([^.a-z0-9]+)/i', '_', $target_filevid);
	   
		if (!move_uploaded_file($_FILES["media-vid"]["tmp_name"], $target_dirvid. $target_filevid)) {
		 
			echo "Sorry, there was an error uploading your file. Please retry.";
		}else{
			
			$vid= $target_dirvid.$target_filevid;
	
			shell_exec("ffmpeg -i ".$vid." -vcodec libx264 -crf 20  out.mp4 2>&1");

		
			}
		}
	}

Here is how I would do it:

Try out this code! ( Tested and works fine )

<form method="post" enctype="multipart/form-data" name="form">
			
																					
<input type="file" name="media-vid"  class=" file_multi_video" accept="video/*">
  
<input type="submit" name="submit" value="upload"/>	

</form>

        <?

    if (isset($_POST['submit'])) {

        if (file_exists($_FILES['media-vid']['tmp_name']) && is_uploaded_file($_FILES['media-vid']['tmp_name'])) {

            $targetvid     = md5(time());
            $target_dirvid = "videos/";

            $target_filevid = $targetvid . basename($_FILES["media-vid"]["name"]);

            $uploadOk = 0;

            $videotype = pathinfo($target_filevid, PATHINFO_EXTENSION);

    //these are the valid video formats that can be uploaded and
                  //they will all be converted to .mp4

            $video_formats = array(
                "mpeg",
                "mp4",
                "mov",
                "wav",
                "avi",
                "dat",
                "flv",
                "3gp"
            );

            foreach ($video_formats as $valid_video_format) {

      //You can use in_array and it is better

                if (preg_match("/$videotype/i", $valid_video_format)) {
                    $target_filevid = $targetvid . basename($_FILES["media-vid"] . ".mp4");
                    $uploadOk       = 1;
                    break;

                } else {
              //if it is an image or another file format it is not accepted
                    $format_error = "Invalid Video Format!";
                }

            }

            if ($_FILES["media-vid"]["size"] > 500000000) {
                $uploadOk = 0;
                echo "Sorry, your file is too large.";
            }

            // Check if $uploadOk is set to 0 by an error
            if ($uploadOk == 0 && isset($format_error)) {

                echo $message;

                // if everything is ok, try to upload file

            } else if ($uploadOk == 0) {


                echo "Sorry, your video was not uploaded.";

            }

            else {

                $target_filevid = strtr($target_filevid, 'ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðòóôõöùúûüýÿ', 'AAAAAACEEEEIIIIOOOOOUUUUYaaaaaaceeeeiiiioooooouuuuyy');
                $target_filevid = preg_replace('/([^.a-z0-9]+)/i', '_', $target_filevid);

                if (!move_uploaded_file($_FILES["media-vid"]["tmp_name"], $target_dirvid . $target_filevid)) {

                    echo "Sorry, there was an error uploading your file. Please retry.";
                } else {

                    $vid = $target_dirvid . $target_filevid;

                }
            }
        }

    }

    ?>
