Today Xbox have announced a partnership with Twitch that includes support for Capture Cards. Before, the only way to broadcast to Twitch on Xbox was by using the Twitch App or just using a Capture Card raw. Now Streamers can use their own Capture Cards to broadcast and be more integrated with Xbox. With this option to stream, Xbox is now “amplifying” streamers content in the following ways.
• The Activity Feed on Xbox One and the Xbox app on Windows 10, iOS and Android
• Notifications to their followers on Xbox One and the Xbox app on Windows 10, iOS and Android
• Game Product Details Page in the Xbox Store
To use the full advantage of using a Capture Card just link your Xbox account to the Twitch app, then just use your Capture Card and broadcasting software on PC and start streaming.
