0x1D78 aAJ_0x1D78_LiveViewMgr_struct_ptr

This ptr (pointer) points to the 0x29D8 byte LiveViewMgr_struct

The actual LiveViewMgr_struct is malloced in AJ_LiveView_Initialise() at 0xFF835DBC

Bit(0x200) : Checked in AJ_LiveView_main(), AJ_GetResource_Res_Free_Count() Have a look at AJ_lv_debug_flag() bit 0 = Enable AE Sequence bit 1 = Enable AF Sequence bit 2 = Output AF RAW Data bit 3 = Output AE RAW Data bit 14 = Output DEFM Raw bit 15 = Output RSHD Raw bit 5 = Enable PSave ON bit 10 = Enable PSave OFF bit 4 = Enable Eshutter (Alex may be interested in this) bit 6 = Enable Magnify (AJ is interested in this!) bit 13 = Enable 30 frm save bit 8 = Change FPS

Set in AJ_LiveView_Initialise()



check AJ_LiveView_main()TST with #0x200. -> if Bit = 0 => possible error
