Special Thanks @ Dave Coffin for dcraw and the bayer extracting to 16bit

Q: I'm able to choose camera2 api, but many things are missing. Why?
A: because its not fully supported by your device. such devices are called legacy devices. they support just basic image capture and recording features. -
Q Why can't i open raw/bayer files?
A Because its the pure data. the decoder cant read it because it does not know how to open it.
To tell the decoder how the data is stored, the dng container is needed.
In that case send us the raw/bayer file and it will work soon. -
Q Why my Device dont show an highspeed video profile, i know it support it
A Its because the Oem's did not add it as MediaProfile and freedcam support it only for most snapdragon socs
- In that case open the VideoProfileEditor inside FreeDcamSetting.
- As sample for 720p highspeed select first the 720p profile.
- Rename it to 720Hfr or what ever you want.
- Change Framerate to 120
- Select Highspeed
- Save the Profile and close the VideoProfileEditor.
- Q Why cant i decompile apps build with nougat sdk
A They changed the dex header version. Use a hexeditor to change the version from 37 to 35 and dex2jar works

First you need a Colorchecker Passport without it, its useless to continue
Set it somewhere in the Scene and capture a Dng from it.
When done you need Adobes Dng Profile Editor
Load there the Dng and choose Chart tab and place the dots to the edges of the chart.
Then click Create Color Table. Now you can tune the matrixes. When done save the dcp profile into camera raw appData folder.
C:\Users\ UserName\AppData\Roaming\Adobe\CameraRaw\CameraProfiles.
Then open the Dng into CameraRaw and go to tab Camera Calibration.
Select there the created dcp profile and click on Save Image... and save the Dng with the choosen profile, do not open the image!
Open the saved Dng now into exiftools or a simliar tool, wich can read metadata, and copy out the matrixes into a txt file in the bottom order.
<matrixes>
<matrix name="G4">
<color1>1.15625, -0.2890625, -0.3203125, -0.53125, 1.5625f, 0.0625, -0.078125, 0.28125, 0.5625</color1>

Can get used to apply custom profiles direct to a dng.
data can get created with various tools.
like from a dcp with dcamprof or dcptools.
or extracted from a existing dng with exiftools.
tonemapprofiles.xml
<tonemapprofiles>
<!-- thats the first profile -->
<tonemapprofile name="linear">
<tonecurve>0,0,0.25,0.25,0.5,0.5,0.75,0.75,1,1</tonecurve> use "," to split. ignores whitespace and line breaks,
<baselineexposure>0.35</baselineexposure> set to avoid the hidden exposure
<huesatmapdims>90 25 1</huesatmapdims> should only contain whitespaces for splitting no line breaks!
<huesatmapdata1>0 0 .... 1 1</huesatmapdata1> should only contain whitespaces for splitting no line breaks!
</tonemapprofile>
<!-- next profile -->
<tonemapprofile name="srgb">
<tonecurve>0,0,......,1,1</tonecurve>
</tonemapprofile>
<tonemapprofile name="iso100">
<baselineexposure>-0.35</baselineexposure>
</tonemapprofile>
</tonemapprofiles>
Copy that file now on your phones internalSD/DCIM/FreeDcam/config/matrixes.xml and you can select it inside Freedcam.
Its gets then applied to each new dng
Create File in /data/misc/camera/camera_dbg.txt
Valid values:
none - no logging
error - error message logging only, default
