basic-tutorial-13.c (playback speed) and gst_event_new_seek entry in core reference contradict to each other
https://developer.gnome.org/gstreamer/stable/gstreamer-GstEvent.html#gst-event-new-seek says:
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?
