It is encapsulated with further, specific encapsulation parameter is as follows:
android::Rect layerStackRect(sourceWidth,sourceHeight)；
android::Rect visibleRect(targetWidth,targetHeight)；
Android::sp<android::SurfaceComposerClient>sc=newandroid::
SurfaceComposerClient()；
MVirtualDisplay=android::SurfaceComposerClient::createDi splay (
android::BufferQueue::createBufferQueue(&mBufferProducer,&
mBufferConsumer)；
mBufferConsumer->setDefaultBufferSize(targetWidth,targetHeight)；
mBufferConsumer->setDefaultBufferFormat
(android::PIXEL_FORMAT_RGBA_8888)。
