Brings the element to the lost state. The current state of the
element is copied to the pending state so that any call to
gst_element_get_state() will return GST_STATE_CHANGE_ASYNC.
An ASYNC_START message is posted. If the element was PLAYING, it will
go to PAUSED. The element will be restored to its PLAYING state by
the parent pipeline when it prerolls again.
This is mostly used for elements that lost their preroll buffer
in the GST_STATE_PAUSED or GST_STATE_PLAYING state after a flush,
they will go to their pending state again when a new preroll buffer is
queued. This function can only be called when the element is currently
not in error or an async state change.
This function is used internally and should normally not be called from
plugins or applications.
