Is this on a PC or on the PS4? I've been thinking of broadcasting on the PS4 occasionally (without the camera). I'm just not sure how it works or what is shown or not in broadcast like the user name shown on/in PS4 desktop. Otherwise I think there are software for PC's that will stream your desktop. As for webcams I think it may be optional but convenient if they can be sub windowed over the chat box to keep player dialog hidden. Could always ask some of the people who make a living streaming games for reviews and such what they use on PC.
