Default [Q] Chromecast with 4.4.2

I use Beanstalk 4.4.2. I have the Chromecast device connected to my TV, and with the Chromecast app in Android I can cast youtube and some other things. Is there a way to cast the entire screen (or whatever video I want, not just the 3 or 4 fixed websites, and including streaming video) to Chromecast? I read that someone added this capability to Cyanogenmod 10.2 and above. I'm not sure what's the status of this capability and whether it exists in Beanstalk 4.4.2.
