This is going to be a series of long posts. With Silverlight Streaming (silverlight.live.com) being discontinued, I thought I’d write up the detailed steps required to host videos using Windows Azure. Since many people who host videos using Silverlight Live Streaming are not technical or development-inclined and rely on the Expression Encoder and Windows Live Writer plug-ins to automate the publishing process, I wrote these posts to suit that audience. In other words, if you can read, understand and follow the steps below, you will be able to host videos on Windows Azure. So don’t be put off by the length and wordiness of these posts – I tried to be explicit to the point of stating the obvious!
Please note that despite its name, Silverlight Streaming was in fact delivering content through progressive downloads. The Azure model is no different. If you are looking for a true streaming approach (e.g. Smooth Streaming), you will need to look at one of our CDN partners.
There are four posts:
Once you have completed the steps in all four posts, you should be able to embed a Silverlight video player in a blog post like the one below:
Credit for all of this goes to a number of people including Saeed Akhter in the Windows Azure team, James Clarke in the Expression team and Tim Heuer. All I’ve done is to synthesize the information that they already put out there.
David, i want to thank you your post has been extremely helpful in setting up the azure service. i have followed your directions to a tee and am through the publish step flawlessly. I do have a question, after encoder published it gives me the option to preview through encoder and it returns an error message. so im not sure if the publish worked. i am still in the process of getting my hosting service to do the Cname reference and then verifying through azure, in order to point to my web site, so i still have a day or so before once all that is done and i can see if it works on my site but it still seems that something is not right and i should be able to see a preview through encoder.
any advice would be much appreciated,
again thanks for all the help

Larry - are you referring to the preview that Encoder pops up (essentially, a locally hosted Silverlight app) or the preview in the publishing section of the Encoder UI?
Assuming you have a publishing point setup on Azure, you should be able to see the published player immediately. If you have activated the CDN functionality, try to hit the non CDN publishing point, since I have found that it can take some time for the content to propagate to the CDN point.
i get this error when i try to preview both the CDN address or the original address on the azure site. "Line :84
Char: 13
error: unhandled error in silverlight application
code: 4004
category: managedruntimeerror
message: System invalid operation exception [net_ui_Notabsolute]"
when i run locally in my browzer local on my computer it runs fine.
Figured it out, i was encoding the video clips as smooth streaming which i guess azure does not support, when i re-encode as H.264 everything publishes fine. Thanks for your help.
Very clean set of step-by-step instructions. Thank you.
I foolowed them completely with no problems until I attempt to Preview the video. In both the orgian and CDN links I get "The webpage cannot be found."
Great stuff!
Any plans for Azure to support the storage of true smooth streams / live smooth streams (not just progressive downloads) to enable us to record from Expression Encoder and publish directly to Azure live?
Just point the silverlight player at an Azure hosted ISML file and BAM!
