Hello, I am still engrossed in the previous topic of the screenshot,
if I got it to work thanks to your help but I do not get the optimal
quality results, this leads me to the conclusion that there is some
option not available in the compilation, so I I decided to compile it
from source, but as I said repeatedly, the verad documentation is
conspicuous by its absence.
Please, I do not need to recommend other projects, I do not need to
recommend other platforms or tools, I just need to know if they know
the correct way to compile it with the environment and configuration
that I am using.my entry is:

$ ./configure --cross-prefix=x86_64-w64-mingw32- --arch=x86_64
--prefix=/usr/local --pkg-config=pkg-config
--pkg-config-flags=--static --extra-cflags=-static
--extra-ldflags=-static --enable-static --disable-shared --enable-gpl
--enable-avisynth --enable-libaom --enable-libfdk-aac
--enable-libfribidi --enable-libmp3lame --enable-libopus
--enable-libsoxr --enable-libvorbis --enable-libvpx --enable-libx264
--enable-libx265

and the response of the configure script is as follows

libfdk_aac is incompatible with the gpl and --enable-nonfree is not specified.
how can I use both combinations? thanks
