This is just a quick and dirty script to extract gyro data from the insta360 video files. It generates a blackbox CSV file.
Place the video file in the root folder and call it video.mp4. Run php gyro.php and it should generate a CSV file with the gyro data.
blackbox has this order for the gyro data:
roll > pitch > yaw
Insta360 order:
pitch > yaw > roll
This is already sorted in the script.
