In my current project I need to encode media files from any format to several predefined. Furthermore I need to track progress and show it for the customer. I don’t want to describe wich media formats I need and what troubles with converting (maybe it will be my future posts, if anybody interested), instead I will describe common idea how to implement encoder scripts and how to track progress.
