Exiftool reporting audio as video.

[abdel@transloadit.com]

I have an audio file that is being reported as video by ExifTool. Not sure what's wrong with the file that is causing this, and if there's a way to fix it.

I have attached the file to this thread. I am using the 12.22 version which is the latest.

This file has a MajorBrand of "iso6", which ExifTool doesn't recognize.  In fact, with a bit of Googling, I see there are also "iso3", "iso4" and "iso5" brands.  If these brands related to specific file contents (ie. if "iso6" should always be an M4A file), then I could identify these properly.  Other than this possibility, the container packages are all identical to MP4.

I did some more googling, and I'm pretty sure that the "iso6" brand may also be used for a video file.

So the only way to distinguish this as an audio file is to look at the content of the tracks and check to see if there is a video program or not.  I'll add this feature to ExifTool 12.23, which should be available later today.

Thank you very much Phil.
