I tried to recompile CinGG's version of ffmpeg with those plugins enabled:

FFMPEG_EXTRA_CFG="--enable-frei0r" (I have frei0r plugins 1.7.0 installed) and after tweaking  /usr/share/cin/ffmpeg/plugin.opts (added frei0r filter_name=vignette at very end of it) I can see this plugin and even use some effects. But not sure where  to find exact documentation for all those parameters?


Apply the colordistance effect, taking a color as the first parameter: 

 Apply the perspective effect, specifying the top left and top right image positions: 

I tried those two and few others (list at the end), they worked, but their configuration a bit unintuitive ....

https://www.dyne.org/software/frei0r/ , it even says
  Frei0r is the result of a collective effort in coordination with several software developers meeting at Piksel between 2003 and 2005 to find a common standard for video effect plugins to be used among their applications: Andraz Tori (Cinelerra/CVS), [..]
