* Answer a segment query by setting the requested values. The normal

* 1.0. If a seek was performed on the pipeline to play a different
* segment, this query will return the range specified in the last seek.

* @start_value and @stop_value will respectively contain the configured
* playback range start and stop values expressed in @format.
* The values are always between 0 and the duration of the media and
* @start_value <= @stop_value. @rate will contain the playback rate. For
* negative rates, playback will actually happen from @stop_value to
* @start_value.
