即使将mime类型更改为'mp4'=> video / mp4并将文件类型设置为mp4，也可以上传mp4视频文件

I am trying to upload a mp4 video file using codeigniter file upload class as follows,

function do_upload_video()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'mp4';
    $config['mimes'] = 'mp4';
    $config['max_size'] = '1000000';

    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());
        $data['main_content'] ='admin/elements/add_video';
        $this->load->view('includes/template', $data);

    }
    else
    {
        $chapter_id=$this->session->userdata('chapter_id');
        redirect("/admin/elements/".$chapter_id);
    }
}

mime type given in mimes.php 'mp4' => 'video/mp4' further, I have also increased the file size in php.ini post_upload_max size and upload_max_filesize to sufficient level.

However when i am trying to upload a sample video file of size 8 MB with .mp4 extension it is showing error as "The filetype you are attempting to upload is not allowed".

Array ( [video] => Array ( [name] => daddyshome_paLrcx9H.mp4            [type]=>video/mp4 [tmp_name] => /tmp/php3xrVFp [error] => 0 [size] => 7350845 ) ) 

getting this on print_r($_FILES)

I removed

      $config['mimes'] = 'mp4';

from my controller and it is working properly.

Set MIME type for MP4 in mime.php

'mp4' => array('video/mp4', 'application/octet-stream'),
