Currently, videocrop, only negotiates raw caps (system memory) because it's the type of memory it can modify. Nonetheless, it's also possible for the element to handle non-raw caps when only adding the crop meta is possible, in other words, when downstream buffer pools expose the crop API. This patch enable non-raw caps negotiation. If downstream doesn't expose crop API and negotiated caps are featured, the negotiation fails.
