Silverlight + MediaSuite = SilverSuite

May 23rd, 2009 No comments

We just introduced SilverSuite for Silverlight 3 with MPEG4.2, RTSP and Flash FLV support. So you can now play RTSP streams and Flash Video streams from your Silverlight applications. The component comes with full source code to the MediaStreamSource classes and therefore allows you to extend or customize them individually. Also included is a policy server and proxy server, that takes care of your cross domain access restrictions if necessary. Check out the demo

How to play Youtube videos from FilePlayer Demo

April 27th, 2009 No comments

I thought I’d share a simple way to play Youtube videos from the MediaSuite FilePlayer demo application.

When opening a video on youtube the url has following form:

http://www.youtube.com/watch?v=[uniqueID]

From that the server generates an HTML page that includes the parameters to be passed to the video players swf file. Using those parameters we can create a new URL to www.youtube.com that will retrieve an FLV file for us.

Simply add another button to the toolbar:

Double-Click it to create an event and insert following code:

Code:

System.IO.Stream stream;
System.Net.WebClient webclient;
webclient = new System.Net.WebClient();
webclient.UseDefaultCredentials = true;
webclient.Headers.Add(System.Net.HttpRequestHeader.UserAgent, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1;)");
try
{
stream = webclient.OpenRead(toolStripTextBox2.Text);
}
catch (System.Exception)
{
return;
}
System.IO.BinaryReader reader = new System.IO.BinaryReader(stream);
string httpTxt = "";
byte[] buffer = new byte[1024];
while(true)
{
int read = reader.Read(buffer, 0, 1024);
if(read == 0)
break;
httpTxt += System.Text.ASCIIEncoding.ASCII.GetString(buffer, 0, read);
}
if (string.IsNullOrEmpty(httpTxt))
return;
string par ="watch_fullscreen?";
int fullscrPos = httpTxt.IndexOf(par);
if (fullscrPos == -1)
return;
int endQuote = httpTxt.Substring(fullscrPos + par.Length).IndexOf("';");
if (endQuote == -1)
return;
int startpos = fullscrPos + par.Length;
string newurl = string.Format("http://www.youtube.com/get_video.php?{0}", httpTxt.Substring(startpos, endQuote + 1));
toolStripTextBox2.Text = newurl;
toolStripButton2_Click(sender, e);

Here’s the end-result for Steve Ballmer going crazy:
