Many applications have multiple objects dealing with audio, and each needs to request audio resources from resource policy manager. Resource policy manager handles audio resources per-manager. Each ResourceSet instance creates new manager, which causes applications having multiple audio objects to fight for the audio resources internally, even though the streams are played from the same process id. To overcome this in QtMultimedia applications, handle all ResourceSet operations through singleton. This way one client has only one manager id registered, and resource acquiring and releasing can be limited to only when no resources are acquired or all resources are freed. To reduce unnecessary noise from resource policy plugin to the clients, keep track of client states and only notify clients which themselves request for resources etc. Change-Id: Ifa4488a9f6298a3f601399e9d339f7bd819be757 Done-with: Juho Hämäläinen <juho.hamalainen@tieto.com> Reviewed-by: Yoann Lopes <yoann.lopes@digia.com>
