Can open produced DNG in Photoshop but not in LibRaw

I have a few questions regarding the Adobe DNG SDK and if i am using it correctly.

So the flow of my program works as follows: i read a custom binary file containing the raw data.

This will be the buffer of my output DNG. I can open the produced DNG in the windows preview correctly and

also in Adobe Photoshop, but if I want to open it in some other programs like LibRaw or RawTherapee, the image

is just completely black.

I will post my programm and the log of DNGValidate.exe , perhaps you have an idea what went wrong.

Here is a link of my DNG.

See my program below

Re: Can open produced DNG in Photoshop but not in LibRaw

Well, one thing I do notice is that there's no thumbnail/preview image. Technically, that's illegal and may be causing trouble.

Re: Can open produced DNG in Photoshop but not in LibRaw

Hi sandy_mc, thank you for the answer. How to set the preview/thumnnail? I think I have it since Windows 10 can show me the a preview, right before "oWriter->WriteDNG(m_dngHost, fstream, *m_pDngNegative.Get(), NULL, dngVersion_1_3_0_0, ccUncompressed);"

Sorry for the bad formatting, i would like to edit my question with code syntax, but i did not find it.
