New progress :
Now i 'm able to dump LV RAW whitout changing(patching) registers setting of chip4000 and chip 4001 , Liveview
video is displayed on LCD screen while dumping LV RAW , the new issue is :
after i insert patch which dumps LV RAW , camera exits Liveview mode automatically after one LV RAW frame is dumped ,
if no dumping code which read LV RAW frame struc_79 , then camera doesn't exit LV mode .
Highlight overflow in LV dumping file doesn't disappear , .

The latest progress :
Dumping LV raw frames (12bits 1664x1100) consecutively is ok while LV video is displayed on camera LCD screen ,
but the new issue is that LV AE controlling is wrong , LV video displayed on camera screen is always much more brighter
or darker than normal exposure level .
It's weird that LV AE controlling becomes abnormal once my patch reads mem of LV raw frame , if no reaing on LV RAW mem ,
then LV AE is good .
Now the key pointer is to understand how LV AE works then hack it .

What happens in Manual Mode? How many frames does it write? Is it continuous? Why are you so awesome?
The d800 has a movie mode where you are totally free from AE if you set the camera to M.

Hi nikkor , Hi all ,
I tested the patch in manual mode , RAW video frames dumped are continous , more than 100 RAW files are stored on SD card within
just several seconds , in total more than 400 Mbytes size .
the most important , video stream pictures are displayed on LCD screen while dumping , meaning the patch becomes practical .
However the patch isn't perfect at all :
1) I have to combined LV RAW patch with LV manual controlling patch , adjust LV shutter speed manually for normal exposure level on LCD displaying .
2) The current patch starts recording LV RAW once Liveview mode is activated , i'm going to add extra codes so that it could be started/stopped
upon specific button pressing .
3) The progress benefit from my guessing of LV RAW backdoor inside firmware ,
but the backdoor doesn't work 100% same as i expected/guessed before ,according to code behaviour and code logic that i understand,
i think/guess the backdoor should compress LV RAW frame at first then store it on SD card , but they doesn't work now ,
i have to insert my patch to dump source data for compressing that i think/guess, since my dumping is right LV RAW , why compressing and storing don't work is still mess to me .
