do_seek
Description:
Update the segment structure with the field values of a seek event (see Event.seek).
After calling this method, the segment field position and time will contain the requested new position in the segment. The new requested
position in the segment depends on rate and start_type and stop_type.
For positive rate, the new position in the segment is the new this start field when it was
updated with a start_type different from NONE. If no update
was performed on this start position (#GST_SEEK_TYPE_NONE), start is ignored and
this position is unmodified.
For negative rate, the new position in the segment is the new this stop field when it was
updated with a stop_type different from NONE. If no stop was
previously configured in the segment, the duration of the segment will be used to update the stop position. If no update was performed on
this stop position (#GST_SEEK_TYPE_NONE), stop is ignored and this
position is unmodified.
The applied rate of the segment will be set to 1.0 by default. If the caller can apply a rate change, it should update this rate and applied_rate after calling this function.
update will be set to true if a seek should be performed to the segment position field. This field can be false
if, for example, only the rate has been changed but not the playback position.
