Instead of

my $ffmpeg = FFmpeg::Command->new('/usr/local/bin/ffmpeg');
[download]

use

my $ffmpeg = FFmpeg::Command->new('ffmpeg.exe');
[download]

or put the path to where you put ffmpeg.exe there:

my $ffmpeg = FFmpeg::Command->new('C:\\Directory\\Where\\I\\Put\\ffmpe
+g.exe');
[download]

You will want to avoid whitespace in the directory names. It might be possible to simply use double quotes though:

# untested!
my $ffmpeg = FFmpeg::Command->new('"C:\\Program Files\\Ffmpeg\\ffmpeg.
+exe"');
