使用PHP将视频转换为MP4

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;

                }
            }
        }

    }

    ?>
