Earlier we have seen this feature in stock Android 8.0 Oreo where you can watch Netflix, prime, maps, and some of the browser videos in PIP mode. In WhatsApp, the feature shows up within the chat window when you receive a YouTube, Instagram or Facebook video.
When you tap the play button the video expands and takes up space on the top half of the app, You can expand the video to full screen or swipe it away to close it. You can also move it around and pause or resume the video, or open the video in the right app – depending on its source. The best part is you can comment about the video in the chat window as both the video and chat remain active.
