  • FFmpeg creates empty palette, for better quality GIF conversion

    FFmpeg creates empty palette, for better quality GIF conversion

    I have referred to

    https://ffmpeg.org/ffmpeg-filters.html#palettegen-1

    https://superuser.com/a/556031/724432

    but it creates an empty pallete file

    I am trying it on android

    the command used is

    {"-y", "-i", j, "-ss", 10, "-t",3,"-vf","fps=15,scale=300:-1:flags=lanczos,palettegen", palette};

    and the error that is shown is
