Example Code - convert to flv throws Exception

[sethkong]

After downloading the latest version of the library, I can now get all example codes to work on Windows 7 except for the convert-to-flv.php example file. Big thanks to Oliver Lillie for your constantly and responsive supports.

Even though it generated correct .flv file, the convert-to-flv.php throws \PHPVideoToolkit\Exception on line 41.

In the post-generated step, it complains that it could not find the $output even though the output was generated.
Please help me resolve this issue, and thank you in advance.

My development environment:
Windows 7
PHP 5.4
XAMPP

[0] => 8
[1] => Undefined variable: output
[2] => C:\xampp\htdocs\www\webedu.local\video\lib\FfmpegProcessProgressable.php
[3] => 292

// Line 136-148 of Flv.php

if($exec->hasError() === true)
{
    if(is_file($temp_output) === true)
    {
        @unlink($temp_output);
    }
if($this->_enforce_meta_data_success === true)
{
    @unlink($output);
    throw new FfmpegProcessPostProcessException('Yamdi post processing of "'.$output.'" failed. The output file has been removed. Any additional Yamdi message follows:
'.$exec->getBuffer());
}
// TODO, log or exception not sure as the original file is ok.
}

Yamdi post processing of "" failed. The output file has been removed. Any additional Yamdi message follows:

That error is a PHP Notice error and can be ignored, however I will patch it at some point. Please post the stacktrace of the exception so I can properly debug the error

I believe this should now be fixed in the latest commit
