It is supported under Linux and Windows.

Prequisities

Install build dependencies

sudo apt-get update -qq && sudo apt-get -y install \
autoconf \
automake \
build-essential \
cmake \
pkg-config \
libsdl2-dev \ 
nasm

Install in system xeve encoder (dev package, main profile)

Detailed and latest info is in xeve.
Install in system xevd decoder (dev package)

Detailed and latest info is in xevd.

Build

To enable EVC in FFmpeg it need to be configured with flags --enable-libxeve and --enable-libxevd

Sample static configuration

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
--prefix="$HOME/ffmpeg_build" \
--pkg-config-flags="--static" \
--extra-cflags="-I$HOME/ffmpeg_build/include" \
--extra-ldflags="-L$HOME/ffmpeg_build/lib" \
--extra-libs="-lpthread -lm" \
--bindir="$HOME/bin" \
--enable-ffplay \
--enable-libxeve \
--enable-libxevd

Shared configuration

For shred build, FFmpeg need to be configured with flag --enable-shared and removed --pkg-config-flags="--static".

Compilation & installation

PATH="$HOME/bin:$PATH" make -j $(nproc)

make install

Examples

Encode

ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -r 30 -i input_file.yuv -c:v libxeve -f rawvideo output_file.evc

Pass encoder specify parameters by using -xeve-params "<param=value>:<param=value>"

ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -r 30 -i input_file.yuv -c:v libxeve -xeve-params "rc-type=0:q=37:profile=baseline:preset=medium" -f rawvideo output.evc

Encoder parameters help

ffmpeg -help encoder=libxeve

Optional parameters:

-threads <num>

Decode

ffmpeg -i input_file.evc -pix_fmt yuv420p output_file.yuv

MP4 container

YUV -> MP4

ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -r 30 -i input_file.yuv -c:v libxeve -f rawvideo output_file.mp4

MP4 -> YUV

ffmpeg -i input_file.mp4 -f rawvideo -pix_fmt yuv420p output_file.yuv

EVC -> MP4

ffmpeg -i input_file.evc -c:v copy output_file.mp4
