I am new to libavfilter and I am currently learning how to develop my own filter for frame analysis. I am using this tutorial/guide, http://wiki.multimedia.cx/index.php?title=FFmpeg_filter_HOWTO, and it feels outdated being modified last on July 2010.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.
Any pointers would be appreciated. Thanks.
