I am trying to compile FFmpeg with SVT-AV1 codec, following instructions from here: https://github.com/OpenVisualCloud/SVT-AV1/tree/master/ffmpeg_plugin

Everything goes well, but when I try to run

./configure --enable-libsvtav1

I am getting 

ERROR: SvtAv1Enc not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

The content of the ffbuild/config.log: https://pastebin.com/euPriFAp

There is an exact issue on the github: https://github.com/OpenVisualCloud/SVT-AV1/issues/35, but is closed as solved.

I have tried both on my Mac and in the Docker container with Ubuntu 18.04, but getting the same result.

Could anyone please help, what am I doing wrong?

The problem was in the lack of requred libraries. Please find the complete installation instruction below.

Installing packages required for compiling:

sudo apt-get update

sudo apt-get install \
  autoconf \
  automake \
  build-essential \
  cmake \
  git-core \
  libass-dev \
  libfreetype6-dev \
  libsdl2-dev \
  libtool \
  libva-dev \
  libvdpau-dev \
  libvorbis-dev \
  libxcb1-dev \
  libxcb-shm0-dev \
  libxcb-xfixes0-dev \
  pkg-config \
  texinfo \
  wget \
  zlib1g-dev

Installing assemblers used by some libraries:

sudo apt-get install nasm
sudo apt-get install yasm

Build and install SVT-AV1:

git clone --depth=1 https://github.com/OpenVisualCloud/SVT-AV1
cd SVT-AV1
cd Build
cmake .. -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
make -j $(nproc)
sudo make install

Apply SVT-AV1 plugin and enable libsvtav1 to FFmpeg:

cd ~
git clone -b release/4.2 --depth=1 https://github.com/FFmpeg/FFmpeg ffmpeg
cd ffmpeg
export LD_LIBRARY_PATH+=":/usr/local/lib"
export PKG_CONFIG_PATH+=":/usr/local/lib/pkgconfig"
git apply ../SVT-AV1/ffmpeg_plugin/0001-Add-ability-for-ffmpeg-to-run-svt-av1.patch
./configure --enable-libsvtav1

(Note: if you want other codecs to be supported please add the required flags to the ./configure command)

Build FFmpeg:

make
make install
hash -r
source ~/.profile

Now you should have ffmpeg command working and have svt-av1 in encoders list:

ffmpeg -encoders

...
V..... libsvt_av1           SVT-AV1(Scalable Video Technology for AV1) encoder (codec av1)
...
