how to inspect the output array from PHPVideoToolkit::getFFmpegInfo()
Quickest way I can think of:


Install the Devel module.
Go to http://mysite.com/devel/php and run the following code:

$info = PHPVideoToolkit::getFFmpegInfo();
dpm($info);



When you run that code you should be presented with a nicely formatted array in the messages area that you can inspect.

If you get an error that PHPVideoToolkit does not exist then find out what file in your installation declares that class, and make sure it's included using either module_load_include() or PHP's include/require.
