Libavfilter is the filtering API of Libav. It is the substitute of the
now deprecated 'vhooks' and started as a Google Summer of Code project.
-Integrating libavfilter into the main Libav repository is a work in

-libavfilter then check it out from the libavfilter repository into

But note that there may still be serious bugs in the code and its API
and ABI should not be considered stable yet!

Video filters are loaded using the @var{-vf} option passed to

chain, and @var{fifo, crop, vflip} are in another. The points where
the linear chains join are labeled by names enclosed in square
