I tried the build and I got this error
ERROR: SvtAv1Enc >= 0.9.0 not found using pkg-config

BTW SvtAv1Enc is installed system wide in this location

/usr/local/lib64/pkgconfig/SvtAv1Dec.pc
/usr/local/lib64/pkgconfig/SvtAv1Enc.pc

=Edit= I solve it by add /usr/local/lib64/pkgconfig/ to the path

PKG_CONFIG_PATH="/usr/local/lib64/pkgconfig:$HOME/ffmpeg_build/lib/pkgconfig:$HOME/lib64/pkgconfig" .

In case of an error regarding makefiles for the libsvtav1.

1. Remove the ffmpeg_sources folder
2. The links for the libsvtav1 github should be changed to https://gitlab.com/AOMediaCodec/SVT-AV1.
3. Rerun the script
