-Integrating libavfilter into the main FFmpeg repository is a work in

-libavfilter then check it out from the libavfilter repository into
-some directory of your choice by:
-
-@example
-   svn checkout svn://svn.ffmpeg.org/soc/libavfilter

-And then read the README file in the top directory to learn how to
-integrate it into ffmpeg and ffplay.

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