File Upload: calculate media playback length in minutes

How can I make my form recognize the upload media length (audio or video) and count the price according to those minutes.

Unfortunately we don't have a way to do what you are asking. But you can create your own way of doing it. Note that this will not be easy. And involve a bit of programming.

You would have to edit the full source code.

And you would need to host this edited code on your own web host.

For example:

https://www.godaddy.com

First you would need to program your own file upload field to capture the media file. You can do this with PHP.

Then get the duration with JavaScript

I managed to put together a demo for you.

You can see it working here:

You need to upload an mp4 movie and when it fully loads press the button to get the duration in seconds.

You can download this small test movie:
