One of the main downsides to the Google Chromecast is its inability to deal with a wide variety of content sources. After all, the device launched featuring official support for just Netflix, Google Movies, Google Music, and YouTube.
Sure, the Google Chromecast also allows for tab mirroring using Chrome and the Google Cast extension on a traditional computer. However, this wasn’t ideal for high resolution video due to various performance issues, and it still failed to provide a suitable solution for local content.
Thankfully, this is where Koushik Dutta of CyanogenMod and ClockworkMod fame comes in. After a couple of public demonstrations through his YouTube channel and Google+, Koush has now released a test APK for AirCast. His app enables you to send any local video from your device’s gallery app to your Chromecast. Furthermore, AirCast also enables you to send a video directly from Dropbox and Google Drive.
For those wondering why this was never released alongside the previous demos, this is because Koush was finally able to reverse engineer the Chromecast protocols and thus get around the developer whitelist restrictions imposed by Google. Unfortunately, the current build of AirCast is limited to only two days of functionality. However, a later build will released under the freemium model.
