Note that we already support those filters through hue, mp=eq and

Why are you adding fade? (it is already integrated since more than one year).
> Afterwards you should be able to apply fades, such as the following: ffmpeg -i input.avi -vf "fade=in:0:30" output.avi
> Question: Can we add a custom filter with out recompiling entire ffmpeg source.For testing it is getting touch to recompile entire code.

I suspect you're looking for plugins, and no it is not likely they
will be implemented.
