Cast request ends in error using iOS SDK 2.7.1

[GoogleCodeExporter]

Hi,
After upgrading the iOS SDK to v2.7.1, casting DRM-enabled videos fails after 
the license request with the following error in the Chrome Debug Console:

Uncaught InvalidStateError: Failed to execute 'webkitAddKey' on 
'HTMLMediaElement': No media has been loaded.

This comes after a 200 OK response for the license request and the debug 
console outputs: [cast.player.core.MediaKeySession] xhr success

Downgrading the iOS SDK to v2.7 without making any changes to either the iOS 
sender code or the receiver code resolves the issue.

I would like to use the latest version of the SDK, but the changelog only 
mentions a fix for setting activeTrackIds to nil, which I'm not doing, so I 
don't know what else to change in my code to make it compatible with v2.7.1.

Reproduced on iPhone 6 running iOS 8.4 & iPhone 6 running iOS 8.3
Google Cast iOS SDK v2.7.1

Also note that casting non-DRM protected videos using the iOS SDK v2.7.1 and my 
same sender + receiver codebases does not reproduce the issue, the videos are 
playing back fine.

I'm using PlayReady DRM protection, which is the only scenario causing a 
failure for me through SDK v2.7.1.
