Hi,

I'm not 100% sure this is the right place to ask but I can't seem to find where the file type of an input file is detected... I would like to know this so I can change things like  'FLAC' into 'Free Lossless Audio Codec' etc. to display as FileType...

Thanks in advance.

There is a description that can be accessed via the API
GetFileType() function.  It uses the following lookup table
(from ExifTool.pm):

Code:

Thanks for your quick reply.. I already found that in the ExifTool.pm file but I was hoping for a solution from the command line. I can't use the API from the command line can I?

I know I need

Code:

my $desc = Image::ExifTool::GetFileType($filename, 1);

If I'd use the API but I don't know how to use it from AppleScript, I only have the option to run command line applications from it. I know OS X can execute perl script from the command line but I don't know if that's what I need for the API. If I only need to run that line (+ setting filename) in a perl script then I can test it.

By the way, ExifTool is awesome!

You can do this by adding a user-defined tag (called "MyType") with this
config file:

Code:

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::Composite' => {
        MyType => {
            Require => 'FileType',
            ValueConv => 'GetFileType($val,1)',
        },
    },
);
1;  #end

See the https://exiftool.org/config.html" target="_blank">config
file documentation for details about how to use a
configuration file.

I realized that this isn't quite right since I am passing the
file type to GetFileType(), but it expects the file extension.
For most files, the file type and extension are the same,
but not for all.  In the next release I will change
GetFileType() to be able to handle this properly for
all file types.

I hit a bit of a snag implementing this.  Some file types are
generated dynamically, so I can't generate a description
for all file types.  I will do what I can to improve GetFileType(),
but to handle the remaining cases the user-defined tag
should be changed as follows:

Code:

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::Composite' => {
        MyType => {
            Require => 'FileType',
            ValueConv => 'GetFileType($val,1) || $val',
        },
    },
);
1;  #end

which will return the original file type if a better
description doesn't exist.

It works. Thank you.
