look at the examples in the ffmpeg/doc/examples directory to get
started. Other than that, reading API docs (which are by far not
complete but improving continously) and looking at code examples (e.g.
in existing filters, look for all the "vf_<filter-name>.c" files or in
some cases ffmpeg.c and ffplay.c themselves) is your best bet.
Depending on how much experience you have in this area, this will
require quite sometime and endurance on your part but it's doable.

Hope this helps a bit.
