The context contains the information from the latest input frame, we're however interested in the information from the latest output frame. As we have to negotiate for the buffer that is about to come next. This should fix some crashes that happened when both information got out of sync. If that happens now, we will do fallback allocation until the output is renegotiated too. https://bugzilla.gnome.org/show_bug.cgi?id=750865
