rw.SECOND_DISPLAY_CONNECTED 對應 dev->wec_disp_connected
rw.secfb.disable-overlay 對應 to_disable_overlay
然後 if(dev->sec_disp_connected&&dev->to_disable_overlay){ if(!dev->to_tvout_display){ property_set("sys.VIDEO_TVOUT_DISPLAY", "1"); dev->to_tvout_display = 1; LOGI("enable VIDEO TVOUT MODE"); } } 也就是說：
SECOND_DISPLAY_CONNECTED 要是 1
secfb.disable-overlay 要是 1
才會 enable VIDEO_TVOUT_DISPLAY
