Facebook Announces Autoplay Sound, Picture-in-picture View, and Other Updates to Video: Facebook rolled out four major updates “that make watching video on Facebook richer, more engaging and more flexible.” These updates include autoplay sound that “fades in and out” and the option to minimize Facebook videos to a “picture-in-picture view” as you continue to scroll through the news feed. Facebook also introduced a larger format for watching vertical videos on both iOS and Android devices and officially announced a new Facebook video app for TV. Facebook’s TV app is expected to roll out “soon” to app stores for Apple TV, Amazon Fire TV, and Samsung Smart TV “with more platforms to come.”
