title: Chromecast DRM License Url - Widevine
body: <p>I have read that Styled Media Receiver supports DRM if the licence URL is embedded in the media manifest.
  The problem is that I want to play mpd pretected content on chromecast. How can I handle the license url and custom data on sender side, without creating a custom media receiver?
  Where I should set licenseUrl? Thanks.</p>
