Anyone used the built in ProgressBar.php with file uploads?

I'm trying to add a progress bar to my mp3 upload form. The form is standard laravel (4.2) with several text inputs (artist, title, email etc) and an upload field. It works and uploads to aws S3.

I can't manage to keep the integrity of my working form and add a progress bar; either the solutions I'm looking at use dropzone or jQuery with their own form and I just can't integrate them or the progress bar bit.

I found that there is a ProgressBar.php in: /web/laravel/vendor/symfony/console/Symfony/Component/Console/Helper/

but I have found no documentation on how to utilise it.

Anybody familiar with this or got any ideas?
