Regarding Error: [AVFilterGraph @ 000000002886ff00] No such filter: 'eq'

First of all, thanks for this wonderful javacv project.

I installed javacv-platform version 1.5.9, ffmpeg-platform 6.0-1.5.9 and trying this filter in the code to adjust the brightness

FFmpegFrameFilter frameFilter = new FFmpegFrameFilter( "eq=brightness=0.25", grabber.getImageWidth(), grabber.getImageHeight()) ;

However, its giving the below error Error: [AVFilterGraph @ 000000002886ff00] No such filter: 'eq' org.bytedeco.javacv.FFmpegFrameFilter$Exception: avfilter_graph_parse_ptr() error -1279870712 (For more details, make sure FFmpegLogCallback.set() has been called.)

Is the downloaded binaries are compiled with the libraries (that includes filters)? Why this error is coming?
