html 使用embed 嵌入wmv格式的视频,怎么做一个图片封面

在前台直接调用
比如你路径放在 E:\1.wmv,
<%=SelPlay(@"E:\1.wmv", 500, 400)%>这样就ok了

.cs文件 直接拷贝，，
/// <summary>
/// 视频播放器(支持avi,wmv,asf,mov,rm,ra,ram),前台使用<%=SelPlay(strUrl, strWidth, StrHeight) %>
/// </summary>
/// <param name="strUrl">视频文件路径</param>
/// <param name="strWidth">播放器显示宽度</param>
/// <param name="StrHeight">播放器显示高度</param>
/// <returns>播放器内容</returns>
public string SelPlay(string strUrl, int strWidth, int StrHeight)
{
// 播放器内容
string html = "";

string Exts = string.Empty;
string isExt = string.Empty;

if (strUrl != "")
{
isExt = strUrl.Substring(strUrl.LastIndexOf('.') + 1).ToLower();
}
else
{
isExt = "";
}

Exts = "avi,wmv,asf,mov,rm,ra,ram";

if (Exts.IndexOf("isExt") >= -1)
{
switch (isExt)
