url - How to get blob URL while a Stram a video from Azure Blob storage

Question

I have a container and a blob of mp4 type in my Azure storage account. I am able to stream it from the Blob.Uri (or using SAS token if required) in HTML5 video control.

But I need to convert that Blob Uri to be converted as "blob:" url so copying the source from developer's tool will not play the video in any new window.

I don't want to download the full video first anywhere.

Thanks in advance!

I am showing/streaming the video like:

List<string> blobPaths = new List<string>();

foreach (IListBlobItem item in container.ListBlobs(useFlatBlobListing: true))
{

    if (item.GetType() == typeof(CloudBlockBlob))
    {
        CloudBlockBlob blb = (CloudBlockBlob)item;
        string sasToken = blb.GetSharedAccessSignature(null, "spolicy");
        blobPaths.Add(string.Format(CultureInfo.InvariantCulture, "{0}{1}", blb.Uri, sasToken));
     }
 }
 ViewBag.Path1 = blobPaths[0];

Main point is that I want Netflix type of feature, so that copying the video source from web page's view source won't work. Also video should not be downloaded locally.
