A quick update to my Motion JPEG Decoder is now available at CodePlex.  Version 1.1 adds the ability to specify username/password credentials for cameras that require a login.  For example:

MjpegDecoder _mjpeg;

_mjpeg = new MjpegDecoder();
_mjpeg.FrameReady += mjpeg_FrameReady;

_mjpeg.ParseStream(new Uri("http://192.168.2.200/img/video.mjpeg"), "user", "password");

As always, questions/comments welcome.  Enjoy!

It's almost time for another MIX conference! Once again I'll be there with the Coding4Fun crew showing off some spiffy new projects for attendees to play around with, along with a few other surprises. I'll also be taking part in John Papa's Open Source Fest on Monday evening, demonstrating WiimoteLib and my MJPEG Decoder.

Anyone else heading to the conference? If you are, be sure to stop by the Coding4Fun area in the Connect Lounge and say hello, and stop by the Open Source Fest on Monday night to take a look at over 50 great open source projects and vote for your favorites. I'd say I'd trade drinks for votes, but those are free, too.

And finally, if anyone attending is working on a fun or interesting project and would like to do an interview for my Coding4Fun Show on Channel 9, please let me know.  Almost anything goes, so I'd love to see what everyone out there is working on.

Hope to see you there!

My latest article and library is now live on the brand new Coding4Fun site, now on Channel 9, and over at CodePlex.  This project allows you to very easily decode a MJPEG (Motion JPEG) stream from a network camera (or any other source) into a consumable type for WinForms, WPF, Silverlight, XNA and Windows Phone 7 (both Silverlight and XNA).

The MJPEG Decoder library started life as a project for the t-shirt cannon built for the MIX10 keynote.  The original plan was to have an IP camera attached to the robot for a real-time video stream from the bot's perspective, but the feature wound up being cut for time, and due to some issues rendering the video on the very early Windows Phone 7 tools.  The library has been sitting around a while, has gone through several rewrites and now supports almost every platform I can think of.  With the new Coding4Fun up and running, it was time to polish it off and get it posted.

I will be speaking at Visual Studio Live! in Las Vegas this April 18-22.  The conference this year is being held at the Rio All Suites Hotel and Casino (to quote Penn Jillette directly) and is a full 5 day event.  The two sessions I’m presenting are:

TH1 - Multi-touch Madness!
Date: Thursday, April 21, 2011
Time: 8:00 AM - 9:15 AM
Level: Introductory to Intermediate

Multi-touch technology is popping up everywhere, most recently in Windows 7 and various .NET technologies. Windows 7 has been designed from the ground-up with multi-touch in mind, and the newest versions of WPF and Silverlight are multi-touch capable as well. In this session I will take you through the 4 biggest areas of Microsoft multi-touch technology: Windows 7, WPF 4, Silverlight, and Surface, including the forthcoming Surface Toolkit for Windows Touch. You will learn how to make your applications multi-touch aware and capable using each of these platforms, how to handle gestures and …

With the official release of NuGet and the NuGet gallery, I decided to try it all out by uploading the current versions of WiimoteLib and ThinkGearNET to the gallery.  The process was pretty smooth, but I learned a little bit along the way which I thought I’d share.

So what’s NuGet?
From their own page:  NuGet (formerly known as NuPack) is a free, open source developer focused package management system for the .NET platform intent on simplifying the process of incorporating third party libraries into a .NET application during development.

In short, this means you can right-click and add a reference to a third party library without having to download it yourself, extract it, locate it manually on your drive, deal with dependencies, etc.  All of this is handled automatically, as is finding and integrating new versions of those libraries with your projects.

NuGet as a User
If you want to use NuGet to download packages, you’ll first need to install the …
