chrome.cast.media.MediaInfo does not accept image data URLs

[GoogleCodeExporter]

Call chrome.cast.media.MediaInfo with a media parameter like 
data:image/png;base64,iVB...

Output is: Error code "invalid_parameter", error description "Invalid contentId 
in MediaInfo."

Should accept such images (if they fit into message bus size limits).

'data' is not a valid parameter for MediaInfo class, use contentType instead. 
Please see class description here: 
https://developers.google.com/cast/docs/reference/chrome/chrome.cast.media.Media

Sorry for not being detailed enough.
I was using a *data URL* https://tools.ietf.org/html/rfc2397

var media = "data:image/png;base64......";
var mimetype = "image/png";

var mediainfo = new chrome.cast.media.MediaInfo(media,mimetype);
var loadrequest = new chrome.cast.media.LoadRequest(mediainfo);
session.loadMedia(loadrequest,...);

In the meantime i have implemented a custom receiver. I am now sending the data 
URL string via sendMessage to my receiver which in turns paints it into a 
canvas.

So the issue could be closed for my application. Initially i thought it would 
be nice to do the rendering in the client app and just send "screenshot" images 
to the standard receiver.

In any case, it could/should appear in the docs somewhere.

Many thanks, best wishes for 2016, from Germany.
