How to add a video in the gallery in laravel

I want to add a video in to the row of gallery column, i am able to upload an image into the row of gallery, and i want to upload the video into that row of gallery as well

The Blade :

<div class="form-group">
                <label class="control-label">{{__("Gallery")}}</label>
                {!! \Modules\Media\Helpers\FileHelper::fieldGalleryUpload('gallery',$row->gallery) !!}
            </div>

The FileHelper :

public static function fieldGalleryUpload($inputId = '', $oldValue = '')
    {
        $oldIds = $oldValue ? explode(',', $oldValue) : [];
        ob_start();
        ?>
        <div class="dungdt-upload-multiple <?php if (!empty($file)) echo 'active' ?>" data-val="<?php echo $oldValue ?>">
            <div class="attach-demo d-flex">
                <?php
                foreach ($oldIds as $id) {
                    $file = (new MediaFile())->findById($id);
                    if (!empty($file)) {
                        ?>
                        <div class="image-item">
                            <div class="inner">
                                <?php
                                $oldPath = '';
                                if (!empty($file)){$oldPath = $file->getEditPath();}
                                ?>
                                <a class="edit-img btn btn-sm btn-primary edit-multiple" data-id="<?php echo $id ?>"  data-file="<?php echo $oldPath ?>"><i class="fa fa-edit"></i></a>
                                <span class="delete btn btn-sm btn-danger"><i class="fa fa-trash"></i></span><img src="<?php echo FileHelper::url($file, 'thumb').'?time='.strtotime('now') ?>" class="image-responsive image-preview">
                            </div>
                        </div>
                        <?php
                    }
                }
                ?>
            </div>
            <div class="upload-box" v-show="!value">
                <input type="hidden" name="<?php echo $inputId ?>" v-model="value" value="<?php echo htmlspecialchars($oldValue) ?>">
                <div class="text-left">
                    <span class="btn btn-info btn-sm btn-field-upload" @click="openUploader"><i class="fa fa-plus-circle"></i> <?php echo __("Select images") ?></span>
                </div>
            </div>
        </div>
        <?php
        return ob_get_clean();
    }
