After a brief google session and ffmpeg docs,
No it's not been merged yet and currently lives in this svn tree:
svn://svn.ffmpeg.org/soc/libavfilter
see README & checkout.sh files, you have to patch,configure and build
ffmpeg yourself.

This thread has some examples from the GSoC student using the new techniques:

Alternatively this page goes into what you want using mencoder:

You may well get better answers from ffmpeg-users list as I haven't
had time to try any of this yet :-)
