mplayer/ffmpeg How to set caca filter's output size

Question

I'm curious how different clips would look like in ASCII art. So I'm trying caca.

To just play, I use mplayer -vo caca $FILE.

But that creates an output of quite small size.

How can I change that size?

Answer 1

Found. Caca library is driven mostly by environment variables rather than filter params.

export CACA_GEOMETRY=200x78
mplayer -vo caca $INPUT
