Hi, I would like to second the support for mp4 files.

On the same, note, .mov also returns the same result:
[{typename: 'pic'}, {typename: 'pif'}, {typename: 'sea'}, {typename: 'ytr'}]

Both .mkv and .webm return this same result so it's impossible to tell which is which (only from the file extension, which could be changed):
[{"typename": "mkv"},{"typename": "mka"},{"typename": "mks"},{"typename": "mk3d"},{"typename": "webm","mime": "audio/webm","extension": "webm"}]

So overall, add better support for video files.

mkv, mka, mks mk3d and webm share the same signature (see: https://en.wikipedia.org/wiki/List_of_file_signatures).

mp4 shall be detected correctly now on version 1.0.10. (https://github.com/LarsKoelpin/magic-bytes/blob/master/src/index.spec.ts#L17)

let me know, if it works for you.
