ckplayer动态调用数据库视频，地址怎么写？（求代码）

Question

插入播放器页面：

                       <input id="hidInfoId" type="hidden" runat="server" value="id" />
                       <script type="text/javascript" src="ckplayer/ckplayer.js" charset="utf-8"></script>
                       <script type="text/javascript">
                        var flashvars = {
                            f: 'url.aspx?id=[$pat]',
                            a:document.getElementById("hidInfoId").value,
                            s: 1,
                            c: 0
                           };

                       var params = { bgcolor: '#FFF', allowFullScreen: true, allowScriptAccess: 'always', wmode: 'transparent' };
                       CKobject.embedSWF('ckplayer/ckplayer.swf', 'a1', 'ckplayer_a1', '600', '400', flashvars, params);
                       </script>

 后台（url.aspx.cs）:

```if (!string.IsNullOrEmpty(Request.QueryString["id"]))
        {

            Response.Write ("视频地址");
        }

最后一步就不会了，试了很多次，视频加载不出来，求大神帮完善，着急！

也可以推荐更简单的方法。

Answer 1

             //Response.Write ("视频地址");
                        ///=>
        context.Response.ContentEncoding = "视频的mime，如mp4这里为video/mp4";
        context.Response.WriteFile("视频地址");
