queryAcceptCaps bool queryAcceptCaps(Caps caps): Check if the given pad accepts the caps.
queryCaps Caps queryCaps(Caps filter): Gets the capabilities this pad can produce or consume. Note that this method doesn't necessarily return the caps set by sending a Event.newCaps - use Pad.getCurrentCaps for that instead. gst_pad_query_caps returns all possible caps a pad can operate with, using the pad's CAPS query function, If the query fails, this function will return filter, if not NULL, otherwise ANY.
