Picture-in-Picture (PIP) mode in a calling application iOS

Описание: This example demonstrates the implementation of Picture-in-Picture (PIP) mode in a calling application that uses WebRTC for VoIP functionality. The sample showcases how a video call continues seamlessly when the app switches to PIP mode. In the PIP window, the app provides action buttons to pause or resume the video stream, ensuring a smooth user experience.

The PiP (Picture-in-Picture) window offers versatile controls:
Drag to reposition.
Single-tap for options like full-screen toggle.
Double-tap to switch between minimized and maximized sizes.
Stash the window by dragging it to the screen's edge, and unstash by tapping or dragging it out.
