This allows us to have more fine-tuned caps in READY or above. However, this is _really_ inefficient since we create a new stream and query sink for every getcaps in READY, which on a simple gst-launch line happens about 35 times. The next step is to cache getcaps results. https://bugzilla.gnome.org/show_bug.cgi?id=686459
