Hello friends,
Today I am going to write one more important article regarding the Video and Audio files in web application. By this application you can view the .avi, .mpeg files in your web browser.   

For this application you should have the avi or mpeg files to load in the web browser. This application contains a list box and object tag with a play button. Depends on your selection from the list box you can find the videos will load in the media player in your browser. Just copy and paste the following code in your .aspx page’s form tag.

=================================================================================================
<div>
<asp:ListBox ID=”lstFiles” runat=”server” SelectionMode=”Multiple”>
<!–HERE YOU HAVE TO GIVE THESE FILES WHICH ARE EXIST IN YOUR PROJECT–>
<asp:ListItem>BLUR16.AVI</asp:ListItem>
<asp:ListItem>BLUR24.AVI</asp:ListItem>
<asp:ListItem>CINEAPK.AVI</asp:ListItem>
</asp:ListBox>
<br />
<asp:Button ID=”Button1″ runat=”server” Text=”Play” OnClick=”Button1_Click” /><br />
<br />
<!–HERE WE ARE USING LITERAL TAG TO WRITE THE HTML DYNAMICALLY–>
<asp:Literal ID=”Literal1″ Visible=”true” runat=”server”></asp:Literal>
</div>
=================================================================================================

Write the following code in your code behind file(i.e. .aspx.CS)  This code will be in your button’s click event.

=================================================================================================
//HERE WE ARE WRITING IN A FILE (test.wvx). THIS FILE IS THE PLAYLIST FILE FOR THE MEDIA PLAYER, LATER WE WILL ASSIGN THIS FILE TO
//THE OBJECT TAG
StreamWriter sw = new StreamWriter(“test.wvx”);
//Write lines to File
sw.WriteLine(“<ASX VERSION=\”3.0\”>”);

for (int i = 0; i < lstFiles.Items.Count; i++)
{
if (lstFiles.Items[i].Selected)
{
sw.WriteLine(“<ENTRY>”);
sw.WriteLine(“<REF HREF=\”" + lstFiles.Items[i].Value + “\” />”);
sw.WriteLine(“<Title>Testing 00</Title>”);
sw.WriteLine(“<Author>CIPL 00</Author>”);
sw.WriteLine(“<Copyright>VBM 01</Copyright>”);
sw.WriteLine(“<Banner></Banner>”);
sw.WriteLine(“</ENTRY>”);
}
}

sw.WriteLine(“</ASX>”);

//Close the file
sw.Close();

StringBuilder sb=new StringBuilder();
sb.Append(“<object data=’test.wvx’ classid=’55274-641-1620264-23142′ runat=’server’ id=’audio’ name=’audio’ type=’video/x-ms-wvx’ style=’width:400px; height:309px’>”);
sb.Append(“<param name=’src’ id=’wvxfile’ value=’test.wvx’ valuetype=’ref’ />”);
sb.Append(“<param name=’showcontrols’ value=’1′ valuetype=’data’ />”);
sb.Append(“<param name=’SendPlayStateChangeEvents’ value=’true’>”);
sb.Append(“<param name=’showstatusbar’ value=’1′ valuetype=’data’ />”);
sb.Append(“<param name=’autostart’ value=’1′ valuetype=’data’ />”);
sb.Append(“<param name=’volume’ value=’0′ valuetype=’data’ />”);
sb.Append(“<param name=’PlayCount’ value=’1′ valuetype=’data’ />”);
sb.Append(“</object>”);

Literal1.Text = sb.ToString();

=================================================================================================

Just go through this code. If you are unable to create file, please give full writes to your project folder. That will allow you to create file named test.wvx. Now run the project. Select the multiple files from the list box and u can see that the files are loading in the web browser in sequenct.

You can add your suggestions and comments regarding this article.

So Enjoy programming….
