Need Swift, Objective C Developer... With FFmpeg experience. Compile old code

Job ID: 35099803

Budget: $10 – $30 USD

I'm in need of a developer to compile some old code for me.
It is for an app that takes a video of any size/dimension and converts it into a square video, by adding padding/border onto the sides of the video.

Here is the code.
The code is from 2015. It is an old app so I'm not sure if the app was created in Objective C or Swift. I think it was created in swift.

I need someone that also understands the basics of ffmpeg. The app may have some of this integrated.
