                redirect('blogs/login');
            }
            $data['title'] = 'Create Blog';

            $this->form_validation->set_rules('title', 'Title', 'required');
            $this->form_validation->set_rules('content', 'Content', 'required');

            if($this->form_validation->run() === FALSE){
                $this->load->view('templates/header');

                $this->load->view('templates/footer');
            } else {
                // Upload Image
                $path = './assets/uploads/blogs/images';
                $config['upload_path'] = $path;
                $config['allowed_types'] = 'gif|jpg|png';

Try this

class Blog extends CI_Contrller{
function create_blog() {
    //  Check Login
    if (!$this->session->userdata('logged_in')) {
      redirect('blogs/login');
    }
    $data['title'] = 'Create Blog';

    $this->form_validation->set_rules('title', 'Title', 'required');
    $this->form_validation->set_rules('content', 'Content', 'required');

    if ($this->form_validation->run() === FALSE) {
      $this->load->view('templates/header');
      $this->load->view('blog/create_blog', $data);
      $this->load->view('templates/footer');
    } else {
      // Upload Image


      $ext = pathinfo($_FILES['userfile']['name'], PATHINFO_EXTENSION);
      $ext = strtolower($ext);
      $image_ext_arr = array('gif', 'jpg', 'png', 'jpeg');

      if (in_array($ext, $image_ext_arr)) {
        $path = FCPATH.'assets/uploads/blogs/images';
        $allowed_types = 'gif|jpg|png';
      } else {
        $path = FCPATH.'assets/uploads/blogs/video';
        $allowed_types = 'mp4|mp3';
      }

      $config['upload_path'] = $path;
      $config['allowed_types'] = $allowed_types;
      $config['max_size'] = 15000;
      $config['max_width'] = 1024;
      $config['max_height'] = 768;

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

      if (!$this->upload->do_upload()) {
        $this->session->set_flashdata('file_error', $this->upload->display_errors());
        $post_image = 'noimage.jpg';
        redirect('blog/create_blog');
      } else {
        $data = array('upload_data' => $this->upload->data());
        $post_image = $_FILES['userfile']['name'];
      }

      $this->M_blog->create_blog($post_image);
      redirect('blog/view');
    }
  }
}

Added few line :

$ext = pathinfo($_FILES['userfile']['name'], PATHINFO_EXTENSION); //to find whether is image or video
      $ext = strtolower($ext);// some time extension in upper later so converted into small letters
      $image_ext_arr = array('gif', 'jpg', 'png', 'jpeg'); //give here all extension of image that you want to upload

      if (in_array($ext, $image_ext_arr)) { //if matches means is image
        $path = FCPATH.'assets/uploads/blogs/images';
        $allowed_types = 'gif|jpg|png';
      } else { //else video
        $path = FCPATH.'assets/uploads/blogs/video';
        $allowed_types = 'mp4|mp3';
      }

Note : Better to give absolute path instead of relative path to upload so

$path = FCPATH.'assets/uploads/blogs/video';
