Convert base64 Video file in Windows Phone

Question

How to convert base64 video in Windows Phone,

I have base64 string :

string str = "aqtuphnzx+rnmhjqipo";

How do I convert?

Thanx!!

That is not a base64 string, it will not have a `+` in the center of the string. Also do you really think a entire video can be represented by 19 characters? Are you sure that the string you have is just not part of a URL for a website or something? — Scott Chamberlain, Jun 06 '14 at 06:20
Well we need more information, for example how was the string encoded? Unicode, UTF-8, UTF-16, UTF-7, ASCII? — Scott Chamberlain, Jun 06 '14 at 06:26
You need to be [updating your question](http://stackoverflow.com/posts/24075445/edit), please remove your comments and instead add the **correct** information to the question. — Scott Chamberlain, Jun 06 '14 at 06:34

You could use the Convert utility class to Convert.FromBase64String() your input to get the raw bytes. You'll probably want to wrap this byte array in a memory stream while you're at it.

var str = "aqtuphnzx+rnmhjqipo";
var videoStream = new MemoryStream(Convert.FromBase64String(str));

Note that your sample str is not actually a base64-encoded string as far as I can tell.

Don't think you can use `MediaElement` for streams. See: http://stackoverflow.com/questions/7117589/using-mediaelement-to-play-video-from-stream – Steven Liekens Jun 06 '14 at 06:55
thank you steven, can you suggest me a good method, Is IsolatedStorage is useful here? – Binjal Shah Jun 06 '14 at 07:00
I've never programmed for WP before, so I'm not familiar with IsolatedStorage files. However, any way to make your video accessible through a URI (that includes file paths) will suffice. Can you save the video to IsolatedStorage and then get its file path? – Steven Liekens Jun 06 '14 at 07:04
steven, I am saving video in isolated storage, but next what to do that I do not know?thank you – Binjal Shah Jun 06 '14 at 07:06
