(From update of attachment 193898)
this patch need some more work:

GST_OBJECT_LOCK (filter)

make PROP_GRID_X/PROP_GRID_Y doesn't work anymore since these properties try to
change filter state and the filter is locked, I would like to change these
setter this way:

case PROP_GRID_X:
      //ret = gst_element_get_state (GST_ELEMENT (filter),
      //    &filter->state, NULL, 250 * GST_NSECOND);
      filter->gridx = g_value_get_int (value);
      if (filter->prevgridx != filter->gridx)
      //    && ret == GST_STATE_CHANGE_SUCCESS
      //    && filter->state == GST_STATE_PLAYING) {
      {
        filter->changed_gridx = true;
      }
      filter->prevgridx = filter->gridx;
      break;

what do you think about?
