Google has been tight-lipped about its plans for Chromecast, leaving developers and users wondering if they'll be able to stream their own local videos and music to the TV screen. While the company hasn't provided a clear answer, recent updates suggest that third-party app development might not be as open as initially thought.

The latest Chromecast update has effectively killed support for AllCast, an Android application that allowed users to stream their personal media to a TV. Developer Koushik Dutta had successfully reverse-engineered the Chromecast's code, enabling playback of files stored in a phone's gallery, Dropbox, or Google Drive. However, with the new software update, things have come to a grinding halt – intentionally, according to Dutta.

The move has sparked concerns about the future of indie developer-friendly fitness app development on Chromecast. While officially, Chromecast only supports media from the Google Play store, Netflix, and YouTube, it seems that Google is keen on actively controlling the user experience and the content that can be streamed. This strategy might help attract new partners like HBO and Hulu Plus.

In an interview with The Verge, Google exec Rishi Chandra emphasized the importance of cooperation between developers and the company if they want to stream content from the cloud. However, he also praised Chromecast's tab casting feature, which essentially gives users limitless viewing options as long as they're watching something in a Chrome browser.

So what does this mean for fitness app development on Chromecast? It seems that Google is still working out the kinks of its Google Cast SDK, which is currently in early development. According to the company, it aims to provide a great experience for users and developers before making the SDK and additional apps more broadly available.

In response to our request for comment, Google has clarified that it intends to support all types of apps, including those for local content. This news might give indie developers like Dutta a second chance to create innovative fitness apps for Chromecast. With the company's full statement below, we can only speculate about what the future holds for Chromecast and its development ecosystem.

We’re excited to bring more content to Chromecast and would like to support all types of apps, including those for local content. It’s still early days for the Google Cast SDK, which we just released in developer preview for early development and testing only. We expect that the SDK will continue to change before we launch out of developer preview, and want to provide a great experience for users and developers before making the SDK and additional apps more broadly available.
