Hello, i have written (basing on drawtext) a simple video filter, which 
utilizes aalib to render input frames as ascii-art and rastarizes this 
ascii-art to output frames using freetype2 library. Also fontconfig can 
be used for font discovery.

Attaching a patch implementing this filter.

Here is example video:


and after applying this filter:

ffmpeg -i disharmony_plain.mp4 -vcodec libx264 -preset slow -crf 18 
-pix_fmt yuv420p -vf 'scale=iw/3:ih/4, 
pad=width=1920:x=(ow-iw)/2' -aspect 16:9 -acodec aac -strict -2 -f mp4 


I hope for suggestions how to adopt this code in order to upstream it.

This is one of my first steps on FOSS world and the first one towards 
ffmpeg suite, so it most likely will be needing a strong scepsis during 
review, because approaches i took most likely wasn't perfect ones to say 
the least.
