Error uploading video with Laravel 5.4

I have the following error that I can not solve being something so simple. I try to upload a video to later save it, but in the process I am shown the following message:

The video failed to upload.

The code of the form is as follows:

{!! Form::open(['url' => '/video/upload','method'=>'POST','enctype'=>'multipart/form-data','files'=>true]) !!}
                        {!!  Form::token();!!}
                        <div class="form-group{{ $errors->has('video') ? ' has-error' : '' }}">
                            <div class="input-group input-file">
                            <span class="input-group-btn">
                                <button class="btn btn-default btn-choose" type="button">Choose</button>
                            </span>
                                <input type="text" class="form-control" placeholder='Selecciona un archivo...'/>

                                <span class="input-group-btn">

                            </span>

                            </div>
                            @if ($errors->has('video'))
                                <span class="help-block">
                                        <strong>{{ $errors->first('video') }}</strong>
                                        </span>
                            @endif
                        </div>


                        <div class="col-md-offset-11 ">
                            <button type="submit" class="btn btn-primary">
                                Enviar
                            </button>
                        </div>
                        {!! Form::close() !!}

The request code where it is validated is the following:

class VideoRequest extends FormRequest{
public function authorize()
{
    return true;
}
public function rules()
{
    return [
        'video' => 'mimes:mpeg4,mp4,mov,avi|required'
    ];
}
public function messages()
{
    return [
        'mimes' => 'El archivo seleccionado no cuenta con algun formato soportado: MP4, MPEG4, MOV, AVI',
        'required' => 'El campo es obligatorio'
    ];
}
}

The route:

Route::post('/video/upload', 'VideoController@saveVideo');

And the driver that is empty, because the request never comes

public function saveVideo(VideoRequest $request)
{

        dd($request);
}

Also configure the php.ini file with the values:

post_max_size=10M
upload_max_filesize=10M
