The QAbstractVideoSurface was started only when calling play(), causing frames received before (e.g. when pausing from stopped state) to not be rendered. The surface is now started as soon as a media type is agreed between the EVR and the upstream element. Conversely, the surface is stopped whenever the media type is cleared.
