I used local file, though also video that I got from youtube
(, I used command:

        CACA_DRIVER=ncurses mplayer -vo caca mteden_daniel

Works in both st (not head/tip, though 0.3 from about a month ago) and xterm,
also surprisingly it seems it even is faster on st! Though I tried this on
quite small terminal windows. At first I tried xterm with full screen terminal
and it was insanely slow.

Terminal size I used: 31 lines 95 columns; There still of course is insane
flickering, but frame rate seems quite decent (on st), though it seems those
frequent refreshes of st window lag wm (dwm) quite a bit, cause while it is
playing dragging even other windows becomes noticeably slower; window dragging
has, what I would call, sliding on ice effect.
