Undocumented Features and Use Case of this Python Package

[pklaus]

It would be helpful to find a bit more information on this software in its README.

As I see it, it can provide a Python-only alternative to extracting the gpmf metadata using ffmpeg. Would there be a reason for using this over ffmpeg and - let's say - pygpmf (see on Github | PyPI)? Maybe for debugging if the 'high level' tools have problems reading and interpreting the data?

Besides: The library hachoir3 was renamed to just hachoir: https://github.com/vstinner/hachoir

pygpmf is 5mo old, this is 3 years... back then this was what I could get working for the use-case I had (batch extracting GPS and accelerometer data from hero5 black videos).

If/when I needed this functionality again I would probably check out the current alternatives and either use them or update this to be more current (probably also use kaitai instead of hachoir etc, depending on full ffmpeg just to parse the fourcc streams is a bit bloated)

Thanks for your response! This clarifies things nicely!
