Widevine DRM Stream crashes Chromecast App on Nexus Player

[GoogleCodeExporter]

The Chromecast implementation of the Nexus Player devices crashes if you cast 
streams or videos which are protected with widevine DRM.

Steps to reproduce:
- Cast a Widevine DRM protected stream, for example use the chromecast demo 
application from https://github.com/googlecast/CastMediaPlayerStreamingDRM 
(Cars.mdp)
- The stream starts playing for a couple of seconds
- the chromecast application crashes
- after a couple of times the nexus player no longer identifies itself as a a 
chromecast and needs to be rebooted 

Android Version: 5.1.1
Build: LMY48J

Expected behaviour: Streams should run as on a chromecast stick

Can you reproduce the issue (including the issue where the Nexus Player no 
longer identifies itself as a Chromecast), enable and capture receiver logs, 
and provide them here as a text file? Also, please provide any stream(s) where 
you saw this issue occurring and make sure they're available for us to test.
