    });

    # Set timeout

    # Convert a video file into iPod playable format.
    $ffmpeg->output_options({
        file   => $output_file,
        device => 'ipod',
    });

    my $result = $ffmpeg->exec();

    croak $ffmpeg->errstr unless $result;

    # This is same as above.

        audio_codec         => 'libaac',
        audio_sampling_rate => 48000,
        audio_bit_rate      => 64,
    });

    $ffmpeg->exec();
