This is simply requesting to play from the start to EOS.

When you receive SEGMENT_DONE, you can seek again to replay from somewhere or
loop. If it does not work, you will need to debug. E.g. when gst_element_seek()
fails dump a pipeline as a dot-graph and check that all pads are active and not
flushing. Maybe some element you use has bugs with seek handling.
