We are trying to do screen broadcasting using replay kit in ongoing video call. If you can provide any demo or sample how ongoing video call can share screen. I have created extension for screen broadcasting but the problem is that how can i change video and audio codec from broadcast extension.

@milan-galitein Thanks for reaching out.

We already have a sample app for screen sharing in a Room with ReplayKit broadcast extension. Example - https://github.com/twilio/video-quickstart-ios/tree/master/ReplayKitExample

Check it out and let me know if you have more questions.

@piyushtank I have already used your demo app. But the situation is like we have ongoing video call where we have already connected to one room . Then after need to do screen sharing using ReplayKit broadcast extension. If you have any idea then just let me know how can we pass video codec from broadcast extension to video call controller?

@milan-galitein Apologies for the late response. You can connect to a Room from your app and while you are connected to the Room, if you like to share screen, you can launch broadcast extension, and connect and share screen from there. Your presenter will be connected from two places - app, and boradcast extension, your app needs to manage this.

Another option is you can use MMWarmHole to supply video frames from broadcast extension when the extension is launched. From app, you will have to share a screen track, with ScreenVideoSource for the frames received from the broadcast extension.

Let me know if you have any questions.
