I have graph2dot FFmpeg utility for converting filtergraph descriptions to the textual representations in the dot language for their subsequent visualisation.

(Thanks to Mulvya who uploaded it in this answer).

It works fine for me but it doesn't recognize some filters, e. g. mpdecimate and delogo:

No such filter: 'mpdecimate'
No such filter: 'delogo'

Is there some way (e. g. a newer version of this program or its DLL libraries) to fix it?

  • My upload was compiled using license LGPL. I need to compile it as GPL to include those filters. I'll do it in a couple of days.

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
