The developer teams from Chrome and Firefox1 have announced core changes to how they will handle Flash applications. Despite being an HTML5-first video player, these changes can affect video playback through JW Player. The announcements indicate that the browser itself will decide whether or not a Flash application is core to the viewer’s experience. If the Flash object is small and outside of view, the browser will throttle or add an overlay on top of the Flash application, stopping it from fully rendering2. This functionality is aimed to help reduce power consumption and increase battery life. Applications that use HTML5 and native <video> tags will not be affected.
