Parse accelerometer metadata from mp4 files recorded on Android #793

Is there an existing feature request for this?

Description

If I understand correctly accelerometer metadata is needed to make "Horizon Lock" feature work. Is that possible to add support for such kind of metadata similar with https://github.com/gyroflow/gyroflow/issues/753? (big-endian, "mett" box, application/gyro and application/accel mime type)

Can you share a sample file?

UnlimitedIllusionsSoftware commented 3 months ago

Sure, here it is (Pixel 6 Pro, NO OIS, 3840x2160, 30 FPS) https://drive.google.com/file/d/1smWmTq_zUF5AE8Ut_keDiUKNhOGgFiZq/view?usp=sharing

this one is good. What's the unit of the accelerometer? m/s² or g?
