示例1: GetLayerState
virtual LayerState GetLayerState(nsDisplayListBuilder* aBuilder,
LayerManager* aManager,
const FrameLayerBuilder::ContainerParameters& aParameters)
{
if (aManager->IsCompositingCheap()) {
// Since ImageLayers don't require additional memory of the
// video frames we have to have anyway, we can't save much by
// making layers inactive. Also, for many accelerated layer
// managers calling imageContainer->GetCurrentAsSurface can be
// very expensive. So just always be active when compositing is
// cheap (i.e. hardware accelerated).
return LAYER_ACTIVE;
}
HTMLMediaElement* elem =
static_cast<HTMLMediaElement*>(mFrame->GetContent());
return elem->IsPotentiallyPlaying() ? LAYER_ACTIVE_FORCE : LAYER_INACTIVE;
