Google opens up Chromecast SDK to app developers

Parent Category: News | 04-02-2014

Google has thrown the doors open to third-party developers looking to write TV-optimised apps by unlocking the Google Cast Software Development Kit (SDK), previously only available to major media partners like HBO, Pandora and Netflix.

Now, a range of developers will be able to write mobile and Web apps that can send content to the Chromecast dongle a streaming video stick that plugs into a TV's HDMI port. The SDK supports Android, iOS and Google Chrome apps/extensions.

"Back in July we announced the developer preview of the Google Cast Software Development Kit (SDK), the underlying Chromecast technology that enables multiscreen experiences across mobile devices (phones, tablet, laptops) and large-screen displays," said John Affaki, engineering manager at Google. "[Now], the Google Cast SDK is available for developing and publishing Google Cast-ready apps."

For simple media applications, developers can use the default media player that can play back HTML5 media content, and they can also customise them with branding and style using CSS.

For non-media applications, or for more flexibility and design options, developers can build their own custom receiver applications using standard Web technologies. With a custom receiver developers can build virtually any application while including support for various streaming protocols, including MPEG-DASH, HLS and Microsoft Smooth Streaming, all of which are available in the Media Player Library.

"The Google Cast SDK is simple to integrate because there's no need to write a new app," Affaki said. "Just incorporate the SDK into your existing mobile and Web apps to bring your content to the TV. You are in control of how and when you develop and publish your cast-ready apps through the Google Cast developer console."
