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? https://ffmpeg.org/ffmpeg-filters.html#frei0r-1 ----- Apply the colordistance effect, taking a color as the first parameter: frei0r=colordistance:0.2/0.3/0.4 frei0r=colordistance:violet frei0r=colordistance:0x112233 Apply the perspective effect, specifying the top left and top right image positions: frei0r=perspective:0.2/0.2|0.8/0.2 ----- I tried those two and few others (list at the end), they worked, but their configuration a bit unintuitive .... List of working effects: colordistance - works edgeglow - works glow - works bw0r.- works posterize - work vignette. - work sobel - work perspective -- work emboss - works sharpness. - works colorize. - works contrast0r. - works squareblur. - works brightness. - works threshold0r. - works (try 0.6 as parameter) equaliz0r - works glitch0r. - works (try 1 as param) gamma. - works pr0file. - works invert0r - works cartoon. - works pr0be. - works saturat0r - works (try 3) dither. - works (try 0.8) primaries - works colortap - works (not sure how to use it) luminance. - works? hqdn3d - works ? twolay0r. - seems to work ? rgbnoise - works sopsat - works (try 0.1) ndvi - works nervous - works (motion effect) colortap - works c0rners. - works vertigo. - works softglow - works spillsupress. - works (not sure what it does) normaliz0r - works tint0r - seems to work (not sure how it was supposed to look) nosync0r/distort0r - not sure how to use them? hue - works ? Site seems to be 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), [..] ===== so, huh :}
