returns the buffering goal, as a duration ahead of the current position, in seconds. This is the amount of seconds after the current position that the RxPlayer will try to preload in the buffer.
Once that value is reached, the RxPlayer won't normally request new media data until the value comes down again (due e.g. to the current position evolving or to a seeking operation).
By default, this value is set to 30.
