I am building FFmpeg with custom options to reduce the final size of apk file on android. I want just convert a mp4 file to a gif. Following is my options specified


 --disable-everything
 --enable-decoder=mpeg4,mpegvideo,aac,gif,h264
 --enable-parser=aac,mpeg4video,mpegaudio,mpegvideo,gif,h264
 --enable-demuxer=mpegvideo,aac,mov,gif,h264
 --enable-muxer=mp4,gif,mov,h264
 --enable-protocol=file
 --enable-encoder=mpeg4,mov,gif,h264
 --enable-filter=scale,fps,copy,palettegen,vflip,paletteuse,crop

What other options do i need to add to successfully run this command?

ffmpeg -y -i input.mp4 -vf "fps=15,scale=320:-1:flags=lanczos" -pix_fmt rgb24 output.gif

ot this command

ffmpeg -y -i input.mp4 output.gif

After I added module into Android Studio I run FFmpeg command. Iam getting this error:

I also tried to include FULL library and it that case everything worked as expected.

Thanks for your help.
