You may use mplayer output & named pipe.
Example:
-==========================================
mkfifo temp.yuv
FNAME=in # input video-file, without extension

# run mplayer in background
mplayer -noass -fontconfig -font "DejaVu Sans" -subfont-autoscale 1 -subfont-text-scale 4.2 -subcp UTF-8 -subfont-outline 4 -subpos 100 -sub $FNAME.ass $FNAME.avi -vo yuv4mpeg:file=temp.yuv -noframedrop -ao null -really-quiet </dev/null &

ffmpeg -f yuv4mpegpipe -i mayo.yuv -i $FNAME.avi -vcodec libxvid -bf 0 -acodec libmp3lame -f avi -y out.avi -map 0.0 -map 1.1

-===========================================
-sub $FNAME.ass - textbased subs, for current example:  in.ass
-subcp  subs codepage
