Google has disabled the video playback feature of the ChromeCast app AllCast, a tool that lets consumers stream their personal collection of videos. Google’s ChromeCast remote control system only supports streaming for content purchased from the Google Play store, Netflix, and YouTube.
Koushik Dutta of ClockworkMod, the company that makes the app, explained the news on his Google+ page calling the move intentional. He writes:
The policy seems to be a heavy handed approach, where only approved content will be played through the device. The Chromecast will probably not be indie developer friendly. The Google TV team will likely only whitelist media companies. I’d strongly suggest holding off on buying a Chromecast until we can see how Google chooses to move forward on third party applications. There are also other (open) platforms and stacks that one could buy/support as well. (LeapCast, NodeCast, etc)
