High quality gif with FfmpegFrameRecorder

Hi, I'm using FfmpegFrameGrabber and FfmpegFrameRecorder to making Gif. First I extract Gif frames by grabber and convert them to bitmaps by Bitmap frameBitmap = new AndroidFrameConverter().convert(frame );

then I do some Edits on Them and convert them to Frame object again. and then make gif of them by recorder. I have tested different PixelFormat But the quality is still bad. also set videoquality to 1. .... from ffmpeg documentation I have found these commands make the Gif with high quality.. ffmpeg -i StickAround.mp4 -filter_complex "[0:v] palettegen" palette.png ffmpeg -i StickAround.mp4 -i palette.png -filter_complex "[0:v][1:v] paletteuse" prettyStickAround.gif is it possible to do this? I know it may be done by FrameFilter but I dont know how...
