Here’s a neat little app we wrote to play YouTube (FLV, H263) videos from a WPF application: http://streamcoders.com/youscoop/
If you are interested in the source code, contact us at support@streamcoders.com
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
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:
Hi Everbody,
MediaSuite.NET 1.0.800 got released yesterday, or the time of frustration for .NET multimedia developers is finally over!
If you haven’t yet seen the features:
All this, available to any .NET developer using Version 2.0 or higher.
The features are pretty amazing and we have put a good 6 months of effort into this software package. It is not only the first all around set of multimedia components for the .NET framework, but also a very easy to use and performance wise not that far behind native code.
You can pretty much create any type of multimedia application with it. You can write a Streaming Server with it. Or make the decoders and encoders part of your softphones media capabilities.
For example, we have written a complete media player for Microsoft WPF from scratch in under (generously spaced) 700 lines of code using only a few buttons and an Image control. It includes more or less a complete video framing infrastructure for H.263, MPEG4 and H.264 and SDP capability disovery.
Download the Trial to see this demo.
We will also start posting useful code snippets and of course continue to extend MediaSuite.NET with some pretty awesome new features in the near future.
