Description

Microsoft Silverlight (announced today) is a cross-browser, cross-platform plug-in that supports rich media delivery over the web. But how do you create the rich media in the first place? Expression Media Encoder is one key element of the workflow: providing encoding, annotation, watermarking, and custom skins.

Dr Sneath visits James Clarke, one of the program managers on the Expression team to see an amazing end-to-end demo that shows the power of Expression Media Encoder and Silverlight working together.

      Whoops. 404 error on download, and only right-channel audio on media stream.

      The download file is still propagating through the cluster... It will not 404 after a little while....

      Not sure about the audio problem.

      Yeah, I'm streaming at 331Kbits / s, just in case you have multiple streams setup. It's definately a problem with the stream.

      Sorry - I think that's my fault. I was using a new professional camcorder, and I was a bit overwhelmed with all the knobs and buttons so I think it only recorded the right audio channel. I'm better with software than hardware - apologies for any inconvenience caused!

      An interesting video. Thanks.

      PS: Tim, I can be a pedantic sod, at times. Which means that when I notice a problem, I tend to be distracted by it, and investigate. I figure there might be a few other like me, so letting them know up front may allow them to see pass it. Good work, anyway. I doubt I could operate a camera AND engage in a coherrent conversation at the same time - assuming you weren't cheating... Smiley

      Is this application freely available just like the previous Windows Media Encoder?

      So, it works on PC and those Mac things, but can only be created on PC because it is designed in WPF. Isn't that a problem...? I mean, I hate Macintosh computers but graphic/web designers (for no apparent reason) love them.

      I have one request Channel 9 - make a new video player using this technology and have it ready for MIX! Tongue Out

      Does this technology allow for buffered content in the way that youtube or soapbox does it? I hate when videos pause to buffer, I'd rather wait for the whole thing to buffer and then watch it.

      Still watching, but is there any server type encoder that could be used for user uploaded files?

      Cool.


      PS Can somebody tell the guys who look after http://www.microsoft.com/silverlight/downloads.aspx that the 1280x768 Background screen for "Silverlight Dusk" is the wrong background?

      That is awesome guys!  For v1 with an end-to-end solution like this is stunning.  So this is kinda an editor and publisher of video in one app?  What is the schedule with .net c# on the client side (i.e. w/o java)?  Seems like .net and is paying big dividends in Spades.  Maybe the theme song should be Motorhead's "The Ace of Spades" Smiley

      Question:  A guy on coffee house asked about publishing his desktop with live video.  Interesting idea.  Seems like if you had some "Virtual" Desktop Web Cam, you could use it as an input just like your doing with other cam inputs.  Is this already possible?

      Thank you good Dr.

      Thank you Dr. for videoing it, James for doing it, and Charles for posting it.

      With videos like this, and blogs by Expression Media Team members, there's an unusual and well-needed personal relationship between Expression Media software developers and users...

      It's an appropriate link to start my new website page devoted to the Encoder...

      http://www.papajohn.org/ExpressionMediaEncoder.html

      It's going to be an exciting and enjoyable path to walk down...

      I can say that I'm very impressed by this demo video, though I'm also a little perturbed.

      The video shows great use of WPF and you guys say you have a directshow engine running in the background.  I know the WPF API (MediaElement/MediaPlayer) gives no exposure to the graph, and there is no way to create your own graph and have it render to a WPF element (unless you use HWND interop).  There is also no method of fast image buffer editing (CopyPixels() and creating a new bitmap is slow w/ video in WPF). 

      I watch like a hawk on blogs and forums and it doesn't seem I'm alone with this fustration. 

      I guess my question is, did you guys use all the public WPF/DShow APIs to make this, or is there a super secret hack?  Whats the secret to a hi-perf dshow/wpf marriage?  Please share...or give me a hint Sad

      Now, we only need a tool like Logic Express or iMovie and GarageBand? Whatever happened to Microsoft Monaco? Was it cancelled?

      Thx for all the great comments.

      Appols for the delay in replying.. we are busy getting the public preview of Expression Media Encoder done.

      Is this application freely available just like the previous Windows Media Encoder?
      >>There will be a free trial.  EME will ship in the Expression Media box and will be freely available to purchases of Expression Studio
       
      Still watching, but is there any server type encoder that could be used for user uploaded files?
      >>EME can be automated in the server context.  I have sample code that I will be posting on my blog www.clarkezone.net

      So, it works on PC and those Mac things, but can only be created on PC because it is designed in WPF. Isn't that a problem...? I mean, I hate Macintosh computers but graphic/web designers (for no apparent reason) love them.
      >>EME works great on Mac hardware via bootcamp.  Not so well in Parallels since they don't virtualize video hardware (yet)

      That is awesome guys!  For v1 with an end-to-end solution like this is stunning.  So this is kinda an editor and publisher of video in one app?
      >>THx..  Yes, although the editing will be extremely rudimentry in v1

      What is the schedule with .net c# on the client side (i.e. w/o java)?  Seems like .net and is paying big dividends in Spades.  Maybe the theme song should be Motorhead's "The Ace of Spades" Smiley
