[FFmpeg-devel] [PATCH] add colours to warnings and errors

How about using termcap/terminfo/* instead of hardcoding ANSI codes ?

Note sometimes the background is actually a (semi)transparent color, 
and forcing a background color fills the whole window with an opaque 
version which really sux visually (vi and others do it).

Btw, there are other options, like underline (4) or video inverse (7).

Indeed, doesn't seem to be available in termcap.

Wow, first time in a while I agree with M?ns :D

It's odd noone came up with some kind of standardization for that...
Maybe we could snoop on the $DIRCOLORS, or .vimrc or .emacs/init.el :D
