ffmpeg displaymatrix: rotation of -180.00 degrees

[dkrstic79]

I am using gopro upside down without rotation lock. after the video is recorded, opening it on my mac, the rotation is correct. when i go to create an overlay, I get the following in the ffmpeg log file:

damirkrstic@Damirs-Mac-mini 10082024 % tail -f /var/folders/41/27zq99ys1szdn2d063z638v80000gn/T/tmpxq19x__l.txt
      Metadata:
        encoder         : Lavc61.19.100 h264_videotoolbox
      Side data:

Once the overlay is generate, both the overlay and video are flipped upside down. How do I change so that the gopro-dashboard is not flipping the video when I run it.

Here are my parameters:

damirkrstic@Damirs-Mac-mini 10082024 % cat ~/.gopro-graphics/ffmpeg-profiles.json 
{
    "overlay-mac": {
    "input": [],
    "output": ["-vcodec", "h264_videotoolbox", "-q:v", "65"]
  }
}

Here is the command that I run to create an overlay:

% bin/gopro-dashboard.py --fit 17237943888_ACTIVITY.fit --profile overlay-mac --font Arial --gpx-merge OVERWRITE nice-ride.MP4 10082024.mp4

and here is the exif for the nice-ride.MP4 itself:

Any help is appreciated.

I've had this happen to me, I am not sure why as I haven't traced it down, but what I did was use a tool called exiftool to add the rotation back. Command I used with exiftool is

exiftool.exe -rotation=180 -api LargeFileSupport=1 GX069613.MP4
