Microsoft has added third-party USB camera support for “Insiders,” or beta testers, on its “Preview Alpha Ring.” It only works with Mixer, not Twitch , and strictly for broadcasting video. So you still need microphone to handle your voiceovers.
USB webcam support is rolling out now to Insiders, and should be completed “in the coming weeks.” In a blog post, the team said it would need feedback from Xbox One owners before it’s comfortable offering the feature to everyone.
