      3264x2448 pixel count matches IMX179 / OV8865 / AR0833 sensors.

      okay. thanks for the tips nutsey. but I don't have any SPI flash tool stuff. I might disassemble the camera someday.

      by the way, the settings menu mimics the Firefly 7s but with fewer features. so it's something more like an Explorer Rexso Dual camera. and the max photo res is 20 MP in settings.

      EXIF from a 20 MP photo shows this res.
      Code:
      ExifImageWidth - 5120
      ExifImageHeight - 3840

      I saw some specs for this cam on Aliexpress and it was nonexistent "IMX079" sensor stated there

    Hello, I make videos with drones and it would be very useful to limit this camera to shutter speeds less than 1/400 or set high iso, One way is to modify the tables of auto-exposure. How can I locate the offset of each video mode in the binary?
