Answer a segment query by setting the requested values. The normal
playback segment of a pipeline is 0 to duration at the default rate of
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.
