Compiling ffmpeg with cuda and shared library

Official Instalation Guide

Remeber to build shared library for all libs. Ex: for libsvtav1 use -DBUILD_SHARED_LIBS=ON in the command.

cd ~/ffmpeg_sources && \
git -C SVT-AV1 pull 2> /dev/null || git clone https://gitlab.com/AOMediaCodec/SVT-AV1.git && \
mkdir -p SVT-AV1/build && \
cd SVT-AV1/build && \
PATH="$HOME/bin:$PATH" cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DCMAKE_BUILD_TYPE=Release -DBUILD_DEC=OFF -DBUILD_SHARED_LIBS=ON .. && \
PATH="$HOME/bin:$PATH" make && \
make install

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig" CC=gcc CXX=g++ CFLAGS="-D__linux__ -U__WIN32__ -U_WIN32 -U_WIN64" CXXFLAGS="-D__linux__ -U__WIN32__ -U_WIN32 -U_WIN64" ./configure   --prefix="$HOME/ffmpeg_build"   --extra-cflags="-I$HOME/ffmpeg_build/include -I/usr/local/cuda/include"   --extra-ldflags="-L$HOME/ffmpeg_build/lib -L/usr/local/cuda/lib64"   --extra-libs="-lpthread -lm"   --ld="g++"   --bindir="$HOME/bin"   --enable-gpl   --enable-gnutls   --enable-libaom   --enable-libass   --enable-libfdk-aac   --enable-libfreetype   --enable-libmp3lame   --enable-libopus   --enable-libsvtav1   --enable-libdav1d   --enable-libvorbis   --enable-libvpx   --enable-libx264   --enable-libx265   --enable-nonfree   --enable-cuda-nvcc   --enable-libnpp   --disable-static   --enable-shared   --disable-doc   --disable-debug   --disable-lzma

make
make install

Don’t forget to dump the cache so that shell can find binaries from $PATH freshly.

hash -r

Add to path

sudo ln -s /home/{username}/bin/ffmpeg /usr/local/bin/

Redo the compiling process

make distclean || rm -rf config.*

Common Errors

Encountering the error ERROR: dav1d >= 0.2.1 not found using pkg-config while pkg-config --modversion dav1d shows the module do existing.

$ pkg-config --modversion dav1d
1.3.0

The reason this error occurs, despite pkg-config seemingly finding the library, is often related to how the build system (like Meson or Autotools) is executing pkg-config. Make sure you have the correct PKG_CONFIG_PATH

export PKG_CONFIG_PATH="/usr/lib/x86_64-linux-gnu/pkgconfig:$PKG_CONFIG_PATH"
