Abstract: In an approach, a first application executing on a first computer acquires, one or more resources of the first computer, wherein the one or more resources include one or more shared resources that are shared among applications of the first computer. The first application receives a media stream from a second computer and presents playback of the media stream. In response to detecting that priority within the first computer has shifted to a second application, the first application pauses playback of the media stream and releases the one or more shared resources while retaining one or more remaining resources that relate to a session context. In response to detecting that priority has shifted back to the first application, the first application re-acquires the one or more shared resources and resumes playback of the media stream based on the one or more remaining resources.
