How to play Youtube videos from FilePlayer Demo
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:
