c#调用暴风影音二组件

c#调用暴风影音2组件
代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices; 
namespace 多媒体播放2
{
    public partial class Form1 : Form
    {
        private System.Windows.Forms.OpenFileDialog openMediaFileDialog = new OpenFileDialog();
        private AxMPSLib.AxStormPlayer player;
        public Form1()
        {
            InitializeComponent();
        }

        private void openToolStripMenuItem_Click(object sender, EventArgs e)
        {
            
            openMediaFileDialog.ShowDialog();
            player.URL = openMediaFileDialog.FileName;
           

        }

        private void exitToolStripMenuItem_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }      
    }
}
怎么调试的时候总是在这个地方（player.URL = openMediaFileDialog.FileName）提示：未处理 System.Runtime.InteropServices.COMException
  Message="对 COM 组件的调用返回了错误 HRESULT E_FAIL。"
  Source="Interop.MPSLib"

需要调用暴风吗，之前写过播放器，如果想播放视频格式多点儿需要ffdshow的dll并且注册。
