basic-tutorial-13.c (playback speed) and gst_event_new_seek entry in core reference contradict to each other
It is not possible to seek relative to the current playback position, to do this, PAUSE the pipeline, query the current playback position with GST_QUERY_POSITION and update the playback segment current position with a GST_SEEK_TYPE_SET to the desired position.
So this text says that we should PAUSE the pipeline. But https://gstreamer.freedesktop.org/documentation/tutorials/basic/playback-speed.html shows us code where we don't PAUSE before seeking. So should we PAUSE or not?
