For opening a Real Player files (.rm) from the server I constructed a .smil file with a .net handler (.ashx file). The smil (Sychonchronised Multimedia integration Language). All details are found in www.w3.org/TR/REC-smil/
The requirement was opening a real player file and the the adminsitrator gives a start timing and end time for the each individual file.
The codes of the smil file was dynamicaly generated from timestamp (begin and end ) from database in ashx file.
The SMIL file looks like this :
<smil>
<body>
<audio src="URL of xxx.rm file" clip-begin="30s" clip-end="40s"/>
</body>
</smil>
The ashx file in VS 2005 can be added through a handler directly and will have two inbuilt functions...
using System;
using System.Web;
public class PlayList : IHttpHandler {
public void ProcessRequest (HttpContext context) {
try
{
context.Response.Expires = -1;
context.Response.Buffer = false;
context.Response.Clear();
context.Response.ClearContent();
context.Response.ClearHeaders();
string mysmil;
string RMFileName = "filename"
mysmil = "<smil><body><audio src=\"";
mysmil = mysmil + RMFileURL;
mysmil = mysmil + "\"";
// insert the smil file here dynamically with file name begin clip and end clip
//<smil>
//<body>
// <audio src="URL of xxx.rm file" clip-begin="30s" clip-end="40s"/>
//</body>
//</smil>
mysmil = mysmil + "/> </body></smil>";
context.Response.AddHeader("Content-Disposition", "attachment;filename=audio.smil");
context.Response.Write(mysmil);
context.Response.Flush();
}
catch (Exception ex)
{
context.Response.Write(ex.Message);
}
}
public bool IsReusable {
get {
return false;
}
}
}

Pour fonctionner avec FireFox, il faut modifier les lignes :
------
mysmil = mysmil + "/> </smil>";
context.Response.AddHeader("Content-Disposition", "attachment;filename=audio.smil");
context.Response.Write(mysmil);
context.Response.Flush();
------
Par :
------
mysmil = mysmil + "/> </smil>";
context.Response.AddHeader("content-type", "application/octet-stream");
context.Response.AddHeader("Content-Disposition", "attachment;filename=audio.smil");
context.Response.Write(mysmil);
context.Response.Flush();
------

C'est aussi par cette solution que vous pouvez gérer le timecode (extrait) des fichiers Real Audio.
