FFmpeg graph2dot tool In FFmpeg Filters Documentation is the section 3 graph2dot is this about graph2dot program:


  The graph2dot program included in the FFmpeg tools directory can be used to parse a filtergraph description and issue a corresponding textual representation in the dot language. 


I have FFmpeg from Zeranoe's build (Windows, 64-bit, static) and I have no tools directory. 

So I tried find this program by Google for downloading it but without success.

Is this part of the documentation obsolete or is it possible to obtain this program?
I don't use Windows, but in Linux you can download the FFmpeg source, then:

cd ffmpeg
./configure
make
make tools/graph2dot


Then you can use it:

echo "nullsrc,scale=640:360,nullsink" | tools/graph2dot -o graph.tmp
dot -Tpng graph.tmp -o graph.png


Resulting in:



Not Windows specific, but maybe helpful for any Linux user who also wants to use this tool.
