In that link you posted, scroll to the bottom and click "Shell Metadata Providers". There's more more information and some sample C++ code.

Here are some other relevant links:

Sorry I can't give you anything more concrete, however it looks like some tag libraries (i.e. for reading MP3 metadata) may work as well, as the metadata for videos seems to be stored in a similar, if not identical, format. That being said, you can give TagLib# a shot.

I've made a simple C# code (portable to Unity, too) csatomreader. It's optimized for speed and can read the atoms over HTTP, too.

E.g. Get title:

using (FileStream stream = new FileStream(fileName, FileMode.Open))
{
    var mp4Reader = new AtomReader(stream);
    string value = mp4Reader.GetMetaAtomValue(AtomReader.TitleTypeName);
    Console.WriteLine($"{atomTypeName}: {value}");
}

If you need to get more metadata values at once, then iterate over ParseAtoms(), e.g. see the GetMetaAtomValue() source.
