Examples of SeekEvent

org.gstreamer.event.SeekEvent
A request for a new playback position and rate.
The seek event configures playback of the pipeline between start to stop at the speed given in rate, also called a playback segment.
The start and stop values are expressed in format.
A rate of 1.0 means normal playback rate, 2.0 means double speed. Negative values means backwards playback. A value of 0.0 for the rate is not allowed and should be accomplished instead by PAUSING the pipeline.
A pipeline has a default playback segment configured with a start position of 0, a stop position of -1 and a rate of 1.0. The currently configured playback segment can be queried with #GST_QUERY_SEGMENT.
and stopType specify how to adjust the currently configured start and stop fields in segment. Adjustments can be made relative or absolute to the last configured values. A type of {@link SeekType#NONE} meansthat the position should not be updated.
When the rate is positive and start has been updated, playback will start from the newly configured start position.
For negative rates, playback will start from the newly configured stop position (if any). If the stop position if updated, it must be different from -1 for negative rates.
It is not possible to seek relative to the current playback position, to do this, PAUSE the pipeline, query the current playback position with {@link org.gstreamer.Pipeline#queryPosition getPosition} and update the playback segment current position with a {@link SeekType#SET} to the desired position.
