ASP .Net获取IP摄像头流

Question

我正在使用以下代码获取IP摄像机流：

    private void Display()
    {
        try
        {
            HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create(url);
            httpRequest.Credentials = new NetworkCredential("username", "password");

            HttpWebResponse myHttpWebResponse = (HttpWebResponse)httpRequest.GetResponse();
            Stream receiveStream = myHttpWebResponse.GetResponseStream();

            Response.Cache.SetCacheability(HttpCacheability.Public);
            Response.AppendHeader("Content-Type", "video/mp4");

            using (BinaryReader binaryReader = new BinaryReader(receiveStream))
            {
                byte[] buffer = new byte[100000];
                while (true)
                {
                    int nbrByte = receiveStream.Read(buffer, 0, buffer.Length);
                    if (nbrByte == 0)
                        break;

                    Response.OutputStream.Write(buffer, 0, nbrByte);

                    Response.Clear();
                    //Response.Flush();
                }
            }
        }
        catch (Exception ex)
        {
            string errMsg = ex.Message;
        }

    }

运行代码时没有发生任何事情。使用浏览器，登录后我可以看到视频。我错过了什么吗？
