Koushik Dutta, who is currently pretty active in developing Google Chromecast enhancements for Android, and who has recently shown some proof of concepts, has yesterday released the first public Beta of its "AirCast" for Android. AirCast is an Android app that lets you share videos from your on device Gallery, Dropbox or Drive to your Chromecast enabled TV. As he wrote on Google Plus, he spent a couple hours on Saturday to "reverse engineer" the Chromecast protocols and he did it with - as he wrote - "great success"! Thanks to the reverse engineering, he's now "able to get around all the developer white-list restrictions"; and because of this he's "actually not using the Chromecast or MediaRouter SDKs anymore".
The use of AirCast is - as he wrote - is straightforward. Open the respective destination, click share, play and control the stream via the remote in the app (or notification area).
The currently offered AirCast APK, which still has some issues (for instance some Gallery apps, like the HTC One, don't show the AirCast button), self-destructs 2 days after installation. It's at the moment another but yet public proof of concept which should helps Dutta to collect bugs and feedback. Therefore Dutta asks for reporting crashes, etc. to make the next public Betas even better.
UPDATE: Koushik Dutta has just released AirCast - Beta 2 which is said to fix HTC One Gallery sharing bug. It's now possible to click the Gallery option and be directed to pick a video. Beta 2 also contains crash fixes and a fix for empty notifications. Some other issuers weren't fixed yet, including that videos stutter on the Samsung Galaxy S3 and some other devices. Also it's said that sharing from Google Drive does not work for some people (can't confirm it with my installation).
