This method returns the range of times in which seeking is efficient.
This method is intended primarily for seeking in media streams that might have excessive latency, such as when playing back media live from an Internet server.
The returned values indicate cached data that has already arrived, which can be easily seeked.
It is assumed that seeking to values beyond these returned parameters will cause a delay while waiting for the data to arrive.
