I stream regularly on Twitch and would like to get a face cam soon. Since I'm streaming over Ps4, I don't know if you need the Ps4 camera or if you can use other Facecams.
As far as I know, this is not possible.
And then if you get a smart pc
Okay, I'll get a PC in about half a year anyway. Would it still be worthwhile to get a Ps4 camera?
No.
Because then you can actually stream on the PC.
A friend once streamed on the PS4 and the PS4 cam also worked as a webcam. I don't know if other webcams support that too.
