Hello Bandit1983 :) , I could able to extract headers from MLV (MLVI , RAWI and VIDF) ,
10:52
Dev2608
code for same, https://github.com/shikamaruNARA17/MLV_TIFF (please see main.cpp )
10:53
Dev2608
i could able to print entries which have standard values ,(please see commit in main.cpp)
10:54
Dev2608
i have used endianhelper.h for this ,
10:54

10:57

ah perfect, the man of the hour BAndiT1983 :)

BAndiT1983
hi Dev2608, you can take a look at the OC implementation, regarding the endianess, but i suspect that the data is raw12 or raw14, so probably you have to dissect it first, so you get each sensel into 16 bit type, like uint16_t
11:01
BAndiT1983
hi se6astian, thanks for assistance, am a bit busy elsewhere today, but will try to check logs or getting irc up on my smartphone

Hello sebastien , sorry for not being specific , this is the output , https://github.com/shikamaruNARA17/MLV_TIFF/blob/master/MLV.png

Dev2608
@bandit1983 , so u mean after extracting the framedata , i need to convert it into 16 bit , is that what mean
11:12
Dev2608
how do i check , is it 14 bit ot 12 bit ,
11:13
BAndiT1983
bits sohuld ben oted in the format, can't find the excel table at the moment
11:13
BAndiT1983
yes, you have to convert, as the 12bit data is concatenated as stream, so your values will be totally off
11:14

11:14
Dev2608
?
11:15
BAndiT1983
yep, thanks
11:16
BAndiT1983
let me first find something different, before checking the specs
11:16

https://wiki.apertus.org/index.php/RAW12
11:16
BAndiT1983
check the bottom for 12bit explanation
11:19
BAndiT1983
seems like i have used only 14bit for mlv loader -> https://github.com/apertus-open-source-cinema/opencine/blob/master/Source/OCcore/Image/MLVLoader.cpp
11:19
BAndiT1983
Dev2608, try to decode it like that, you can find processing for 14bit in bayerframepreprocessor class
11:23
Dev2608
okay , Did u check main.cpp , is it okay for reading the header , so i am safe for that side atleast !
11:25
Dev2608
i see , so we need to check bits_per_pixel for checking the type of RAW data , it was 14 in this case also , i checked it .

sorry Dev2608, had not much time to check your stuff thoroughly yet
11:44
BAndiT1983
just check how OC does it, no guarantee that it reads everything, as it was a prototype
