Hi,
currently the media player doesn't check the return values of
gst_element_set_state(). It should really do that.

If it's SUCCESS, NO_PREROLL or ASYNC everything is fine (errors will be posted
as bus message), if it's FAILURE things should fail immediately (there will be
no error messages on the bus in the worst case).

This is only for state changes from NULL or READY to PAUSED or PLAYING.
Downwards state changes can fail but you're usually not interested in that.
