Silverlight 3 Launches, Complete With GPU-Acceleration

Watch out Adobe: Microsoft Silverlight 3 has launched and boy is its feature list something for Flash's makers to pay just a little attention to. Foremost in the feature set: the addition of GPU-acceleration; though codec support has been improved, too.

The latest codecs to be added to Silverlight are H.264 are MPEG-4 video and AAC audio as well as a raw bitstream audio/video API. It's not hard to guess what GPU-acceleration of Silverlight will mean for consumers with PCs able to take advantage of it.

Multi-touch support is touted, alongside less inspiring upgrades such as improved deep linking, navigation, SEO and library caching support - thrilling stuff I'm sure all you non-developers will agree.

Silverlight 3 also brings persistency outside of the browser to Silverlight-based applications. Or, in other words, you can open a Silverlight app from, say, Firefox into a new Window and it will carry on running if Firefox is closed.

I highly recommend checking out Microsoft's Smooth Streaming demo if you want to see what Silverlight can offer. Sure, on an ideal web where stable high-bandwidth connections are prevalent such dynamic bandwidth adaptation would be unnecessary, but those of us not living in Cloud Cuckoo Land will no doubt appreciate how cool it is flicking through a web-based high definition video without constant pauses and only short drops in quality. And remember, things can only get better as more developers get on board.



Smooth Streaming demo.

Bah doesnt work on Opera. I still cant figure out what Silverlight actually is

It's pretty much just Flash but made by Microsoft. But if enough people express interest I expect we can consider an article with more details :)

Firstly that short film was great I absolutely loved it; I hope that doesn't make me sound immature.

Secondly I often stream HD on youtube, Game Trailers and iPlayer (or whatever the highest resolution is. It maybe the quality of the animation but I can't believe I diddn't

Firstly that short film was brilliant thanks for the link TR.

Secondly I often stream HD and very rarely do I have to wait for it to buffer. The clip I just watched looked absolutely beautiful and streamed perfectly at its highest res. Navigation was instant I was very impressed. But how exactly does it differ from flash? The smooth streaming for lower bandwidth users is also brilliant.

I want Sony to create a HD movie streaming service for the PS3

If you want to test Silverlight, here is a great demo made by microsoft.


It is really impressive! In the top right corner of the video, you can limit the bandwidth and see what effect it has. Silverlight adapts to the bandwidth smoothly.

...another "bah" from an Opera user


July 11, 2009, 12:06 am

Bah works on Opera. You're doing it wrong. And the idea is liked by me. Uh... Impressivo!


July 11, 2009, 12:06 am

Yeah, lots of features is all very well but supporting the established browsers needs to come first.

Sorry for this posting, but I'm tired of people bashing some product/plugin because it doesn't work on one thing.

Opera... - are you actually serious? Can you count how many people actually use this wretched browser? Probably - put your hands in front of you, count how many fingers you have... That's about it. (Save for phones, and that'll be soon once MS get something decent on WinMo rather than Mobile IE)

It works beautifully with Opera 10!


July 11, 2009, 2:04 am

@Xiphias - That particular video works on Chrome on my PC and Silverlight works on Safari, FireFox and IE. That to me seems like the established browsers are covered by Silverlight.

Stick to weddings if this problem is too tricky for you.


July 11, 2009, 5:32 am

Oh im sorry I stand corrected it does indeed work on Opera 10, whatever the hell it is


July 12, 2009, 3:54 am

Wow that anim was excellent - Made in the Open Source 3D app known as Blender

What apps can output Silverlight?? I know that Xara Xtreme and Serif's DrawPlus X2 & X3 can output some flash anything in the low end software range that can do silverlight?

viewed in chrome without a problem ;-)

July 12, 2009, 10:54 pm

Maybe i am being an ubuntu-n00b but i can't see to get it to work.


July 13, 2009, 2:53 pm

@Tony Walker

Silverlight has an open source implementation that runs on the Mono platform, Moonlight, although it always lags a bit behind the official implementation.
