Motivation

I ran into the problem of having many video files of various formats that needed to run on a raspberry pi. So i needed a script to convert all of them for playback in a format that raspberry pi can run.

You could of course just loop through all the files. Though i found the following issues:

Problems:

• There is no ETA on when the script will finish.
• Files would be scattered in the file system.

So i decided i wanted to write a more specific program for the job.
