FFmpeg tool graph2dot doesn't recognize some filters
The older upload did not cover those filters as they require GPL license and the older binary was built with a LGPL configure.

I've uploaded a 64-bit GPL3 Windows binary of graph2dot (with 4 dependencies) to http://www.datafilehost.com/d/6fcd14be
