As livestreaming continues to proliferate throughout the internet, issues have started to emerge that raise the question of how to best use these services. A concern for creators — including broadcasters who are integrating their systems into tools like Periscope and Facebook Live — is how to better control who sees their videos. And yet, there hasn’t been an official way to constrain broadcasts by geography, until today.

Levee is an application that lets you generate Facebook Live posts targeted to specific locales, while allowing you to stream those posts from any commercially available streaming software. Levee was developed by the team at iSL — an experiential agency that’s a Facebook media solutions partner. It’s been open-sourced and is available for anyone to use. As it happens, iSL is also the firm that’s working with USA Networks to promote the hit television show “Mr. Robot,” which “leaked” its second season premiere online yesterday.

In a blog post, iSL CEO Peter Corbett explained that Levee is a “super useful tool for companies like…NBCUniversal and Viacom, who have programming that is rights restricted to specific regions of the world.”‘

To use this application, you’ll need to authenticate using your Facebook credentials and then specify the page that you want to create a livestream for. From there, add a new live video with the title, description, and the countries you want to target. You’ll receive a livestream address that you can stream video through, using an application of your choice. Corbett cautions that once you’ve geo-targeted a video stream, it cannot be embedded outside of Facebook.
