Not sure whether I get it correctly!. I think we need a fixed caps anyways.
Basically negotiation happened based on query caps (eg: for a manual pipeline,
not playbin) and h24parse will return a "video/x-h264" as supported caps. But
after that it requires a fixed caps during GST_EVENT_CAPS. right??
