It would be awesome if it's possible to customize your Playstation4-stream in Twitch Studio.
Maybe you can use the stream code to Synchronize playstation4 and Twitch Studio Beta. So we can have different layers in our stream without buying a third party device such as a Elgato HD60.
Where the PlayStation has a web browser in addition to being able to play the twitch app, youtube, etc. That it wouldn't be too far fetched. However, in regards to this topic. One must remember. Its not Twitch that makes the call when all is said and done when it is regards to this topic.
This is something that the console's parent companies would have to decide to allow to happen. Because no matter if it is made and can happen, unless the company decides to allow it upon the system or at least access to the system ( which in Sonys case will likely be never ) there is not much Twitch nor the creators would be able to do, besides having access to a computer or even a chromebook to be able to control the overlay for their conent.
It would be amazing if we could use the STUDIO to just manage a PlayStation stream, for example.
So you could stream directly from the PS4/5 to twitch and add webcam, other layers and layouts from the studio.
I would love this to be possible on my Xbox. I actually got to this page while trying to find out if Twitch could possibly be working on enabling console streamers to do this. I do not want to invest in a capture card only to find out later that Twitch will enable this.
