m4a mime type

[dubrovine]

filetype van - 1.1.3

Uploading audio file with .m4a extension and its detected as video

filetype.IsVideo(buf) == true
filetype.IsAudio(buf) == false

types.Type={{video 3gpp video/3gpp} 3gp})

I believe it should be something like audio\m4a

[arpanbag001]

Same here. It detects as video/mp4

I believe it should be audio/mp4 instead.
