It contains videocrop ! videoscale ! capsfilter and implements digital zooming. At this moment, it is a private element of the camerabin plugin. This will remove some code used in wrappercamerabinsrc to make code clearer and digitalzoom can potentially be used by other applications in the future, it has nothing camerabin specific.
