using builtin_profiles nnvgpu profile, output video vertical direction is reversed

Does anyone have the same problem?

My solution, which is just one possible solution to this problem, was to create a user defined profile in the json file in my home directory that copied the parameters of the built-in profile exactly but had this line for "filter"
"filter": "[0:v]rotate=PI:c=none:ow=rotw(0):oh=roth(0)[rotate0];[rotate0][1:v]overlay",

I named it something like "nnvgpu-rotated". Ffmpeg will rotate the gopro footage 180 degrees when it prepares the overlayed footage.
