Streaming Video from Azure Blob Storage

By default Azure Blob Storage and Video do not mix well; the first hurdle that developers must get over is that the Content Type for the video must be set correctly (for .mp4 videos that’s usually video/mp4).

The next problem that you’ll face is that the video will not seek correctly; trying to jump forward or backwards in the video won’t work.

This is resolved by changing the DefaultServiceVersion to 2011-08-18 which can be achieved via the Azure’s REST API, or the Managed C# Library as laid out at the end of this MSDN blog post.

var account = CloudStorageAccount.Parse(ConnectionString);
var blobClient = account.CreateCloudBlobClient();
blobClient.SetServiceSettings(new ServiceSettings()
    {
        DefaultServiceVersion = "2011-08-18"
    });
