Hi Valary, ImageStream is updated by a background thread. The xine-lib and QuickTime plugins both subclass from ImageStream and OpenThreads::Thread to provide a class that automatically runs updates on itself - this thread updates the image data on the ImageStream and then calls dirty to tell the rendering thread that it needs to download the data to any associated texture.
