What does the new function "AF key" in the video settings of the "allbest-a720-100c-51-425" do?

Press this key ('set' or 'shutter-half') during video recording: camera makes single autofocus scan. I don't know how it works n a720, but it works good on a650 (also a710, a610, a620).

Here wap4 reported that some exposure control functions (also ExpCtrlTool_StartConti()) crashes DRYOS cameras. So, ExpCtrlTool_StartConti() for DRYOS replaced by nullsub(). Unfortunately, I have only VxWorks camera and cannot debug this functions on DRYOS. Maybe, someone else?
