Since you configured the playback segment to play to the end of the
stream, the SEGMENT_DONE message is posted as soon as the last byte of
the data is pushed in the pipeline (by the demuxer or source).

In light of this, your question does not make any sense. What are you
trying to do?

What do mean with 'NEW_SEGMENT values'? Maybe you mean changing the
playback segment start and stop values? Maybe you mean the values of the
NEW_SEGMENT event?

What's a 'seek for NEW_SEGMENT'? maybe you mean that you want to perform
a segment seek? In any case, this has nothing to do with state changes. 

In general, seeking can be done in either PAUSED or PLAYING. Performing
a non-flushing seek will usually block the caller until the PLAYING
state is reached (so you usually want to perform non-flushing seeks in
PLAYING).
