• Add NVEnc.auo2 as new native AviUtl2 plugin.
• Improve vpp-subburn quality by updating libass and linking harfbuzz. ( #717 )
• Add feature to use filters with avcodec encoders (mainly for my test purpose, #718 ).
  • Available with -c av_xxx, with option to set encoder options (--avcodec-prms).
    Example: -c av_libsvtav1 --avcodec-prms preset=6,crf=30,svtav1-params=enable-variance-boost=1:variance-boost-strength=2"
    Other codec options include av_libvvenc, av_libvpx-vp9, etc.
