Smooth streaming video from Blob storage

I have an MVC 4 application that contains a view to show "Video" only from the azure MP4 memory blog. I am currently using MediaElment.js (or any regular flash player) as a video player. How can I play these videos in smooth streaming or progressive download mode (Adaptive streaming). What are the configurations that I have to install in Azure to support streaming? Is there anything I need to do before uploading an MP4 file to blob storage?

I went through this link http://msdn.microsoft.com/en-us/spazuretrainingcourse_spblobstorageazure.aspx , and as I understand it, Windows Azure Blobs Uploader is used to upload video files in azure and silver as a client. In my case, the video is downloaded from a separate application, so manipulating the video file is not possible. So, is there a way to implement streaming without any changes and play it in a video player other than using silverlight ?.

Is there anything I can do if I can change the media file at boot time?

Thank.
