Hi Tal,

Sorry for the late response since I was busy on other project.

My colleagues and I did some research and we found only the final output file has the black/white problem you mentioned, so I checked the readme of sample_encode.exe:

In the optional argument, it says the default input format is YUV420, since the output of sample_vpp.exe is NV12, this is the issue. You should add "-nv12" in the middle of the command so it becomes

sample_encode.exe jpeg -i out_modifed.yuv -nv12 -o outputfile.jpg -w 1706 -h 1280 -sw -q 100

I have checked outputfile.jpg and it has the correct color.
