用ASP.NET传输视频

有没有一种好的方法可以将视频通过ASP.NET传输到普通网页和移动设备?我已经尝试了以下方法,但它在我的Sony Ericsson K810i中不起作用。当我在浏览器中尝试时,我可以看到这个剪辑(不知道它是否在流媒体)。

HTML:

<object type="video/3gpp" 
        data="handlers/FileHandler.ashx" 
        id="player" 
        width="176" 
        height="148" 
        autoplay="true"></object>

文件处理程序.ashx( Best way to stream files in ASP.NET ):

public void ProcessRequest (HttpContext context) {

    string path = "~/files/do.3gp";

    string localPath = context.Server.MapPath(path);

    if (!File.Exists(localPath))
    {
        return;
    }

    // get info about contenttype etc 
    FileInfo fileInfo = new FileInfo(localPath);
    int len = (int)fileInfo.Length;
    context.Response.AppendHeader("content-length", len.ToString());
    context.Response.ContentType = FileHelper.GetMimeType(fileInfo.Name); // returns video/3gpp

    // stream file
    byte[] buffer = new byte[1 << 16]; // 64kb
    int bytesRead = 0;
    using(var file = File.Open(localPath, FileMode.Open))
    {
       while((bytesRead = file.Read(buffer, 0, buffer.Length)) != 0)
       {
            context.Response.OutputStream.Write(buffer, 0, bytesRead);
       }
    }

    // finish
    context.Response.Flush();
    context.Response.Close();
    context.Response.End();

}
