You assume right. What you wrote in your previous message is correct.
You need to wait for the pipeline to be prerolled (reach PAUSED state,
ASYNC_DONE message on the bus) before you can send a seek. And usually
you will want to do a flushing seek, so set the FLUSH seek flag on your
request (and for a media player usually also the KEY_UNIT flag).
