png2br

2-in-1 PNG to ASCII art converter and ASCII video player.

Works on Windows (good luck installing libav) and Linux.

No sound (never got to implement it).

There are some configuration defines in avtest.cpp, feel free to play with the values.

Three thresholding algorithms are implemented:

• Binary thresholding
• Ordered dithering
• Floyd–Steinberg dithering

• A C++20 capable compiler
• pkg-config
