 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
-ffmpeg or to avplay. Filters in the same linear chain are separated by
+avconv or to avplay. Filters in the same linear chain are separated by
 commas. In our example, @var{split, fifo, overlay} are in one linear
 chain, and @var{fifo, crop, vflip} are in another. The points where
 the linear chains join are labeled by names enclosed in square
