Avisynth

Build

• From AviSynth doc:
• And Can AviSynth on Linux work (Ubuntuforums).

Build avisynthplus

• Instruction from AviSynth doc, added libdevil-dev as suggested on Ubuntuforums.
• This creates and installs a nice deb package.

sudo apt-get install build-essential git cmake checkinstall libdevil-dev pkgconf ninja-build
# +libdevil-dev from ubuntuforums post

# Build (copy-paste from avisynth doc):
git clone --recursive https://github.com/AviSynth/AviSynthPlus && \
cd AviSynthPlus && \
mkdir avisynth-build && \
cd avisynth-build && \

cmake ../ -G Ninja && \
ninja && \
    sudo checkinstall --pkgname=avisynth --pkgversion="$(grep -r \
    Version avs_core/avisynth.pc | cut -f2 -d " ")-$(date --rfc-3339=date | \
    sed 's/-//g')-git" --backup=no --deldoc=yes --delspec=yes --deldesc=yes \
    --strip=yes --stripso=yes --addso=yes --fstrans=no --default ninja install

Build avs2yuv

• Suggested by ubuntuforums, to test avisynth installation

git clone https://github.com/DJATOM/avs2yuv.git && \
mkdir -p avs2yuv/build && \
cd avs2yuv/build && \
cmake ../ && \
make && \
sudo make install

• Test avisynth works as expected. Create a file version.avs:

Version(pixel_type="YUV420P8")

• Play it:

avs2yuv test.avs -o - | mpv -
# Alternatively:
avs2yuv test.avs -o test && mplayer test

• Re-build ffmpeg package with avisynth enabled

sudo apt install nasm libsdl2-dev devscripts fakeroot build-essential dpkg-dev debhelper dh-autoreconf
sudo apt-get build-dep ffmpeg
apt source ffmpeg
cd ffmpeg-6.1.1/
vi debian/rules
# Add --enable-avisynth to CONFIG lines
dch --local +avisynth
# Tell '* Enable avisynth'
# Rebuild with test disabled
# - We can run the tests manually with:
#     export LD_LIBRARY_PATH="libavcodec:libavdevice:libavfilter:libavformat:libavutil:libpostproc: \
#         libswresample:libswscale";      dh_auto_test -a --sourcedirectory=debian/standard -- -k
# - The failing test is some obscure test about headers missing in some include
DEB_BUILD_OPTIONS=nocheck debuild -us -uc
# This may fail because of some library not present: libGL.so
# This library comes in principe with libgl-dev, but it seems even reinstalling it doesn't create the the symlink
# If so:
#     sudo apt install --reinstall libgl-dev
#     cd /usr/lib/x86_64-linux-gnu/
#     sudo ln -s libGL.so.1 libGL.so
#     cd ~/build/ffmpeg-6.1.1/
#     DEB_BUILD_OPTIONS=nocheck debuild -us -uc
cd ..
# Install the new ffmpeg
# - We take the extra version of packages.

. install-ffmpeg.sh
sudo apt install -f

• Check that ffmpeg accepts *.avs file:

ffplay -i version.avs

Build ffms2

• We follow the avisynth doc / ubuntuforums.

git clone https://github.com/ffms/ffms2
cd ffms2
l /usr/local/include/|grep avisynth
PKG_CONFIG_PATH=$HOME/ffmpeg_build/lib/pkgconfig \
CPPFLAGS="-I/usr/local/include/avisynth" \
./autogen.sh --enable-shared --enable-avisynth && \
make -j$(nproc) && \
sudo checkinstall --pkgname=ffms2 --pkgversion="1:$(./version.sh)-git" \
--backup=no --deldoc=yes --delspec=yes --deldesc=yes --strip=yes --stripso=yes \
--addso=yes --fstrans=no --default

# Add ffms2 to avisynth
cd /usr/local/lib/avisynth/
sudo ln -s ../libffms2.so libffms2.so

• Test that avisynth script accept the FFmpegSource2 command:

cat test.avs
# FFmpegSource2("test.mkv",atrack=-1)
ffplay -i test.avs

QTGMC

QTGMC is an anti-aliasing filter for avisynth.
