I am using this tutorial/guide, http://wiki.multimedia.cx/index.php?title=FFmpeg_filter_HOWTO, and it feels outdated being modified last on July 2010. The example it uses, vf_negatem, does not exist any more. Also the libavfilter documentation packaged in the ffmpeg source only describes what they are, now how to write one.

Extract the code from ffplay.c or ffmpeg_filter.c.
