1. Genaral info
#######################################

The patch provided below contains an integration layer between ffmpeg
framework and EVC codec implementation.
In nutshell, it enables using EVC codec (encoding, decoding)  by the means
of ffmpeg API. 
I'd like to emphasize one more time, that (as mentioned before) it isn't
codec implementation. The provided implementation serves as an integration
layer between ffmpeg framework and the EVC codec.

EVC codec has been published as two separate libraries. 
The first one called XEVE (eXtra-fast Essential Video Encoder) is an
opensource MPEG-5 EVC encoder.
The second one called XEVD (eXtra-fast Essential Video Decoder ) is an
opensource MPEG-5 EVC decoder.
For more information on both libraries please follow the links below:
* https://github.com/mpeg5/xeve 
* https://github.com/mpeg5/xevd 

The patch provided below should be apply to FFmpeg 5.0 release (commit
b655beb025cb54ba19cad89e731990910643f208 release/5.0)

2. Building
#######################################

3.1. Download, build and install dependencies

Dependencies:
* eXtra-fast Essential Video Encoder (XEVE) (https://github.com/mpeg5/xeve)
* eXtra-fast Essential Video Decoder (XEVD) (https://github.com/mpeg5/xevd)

-------------------
2.1.1. XEVE
-------------------
git clone git@github.com:mpeg5/xeve.git 
cd xeve

-------------------
base profile
-------------------
mkdir build_base
cd buid_base
cmake .. -DSET_PROF=BASE
make
make install

-------------------
main profile
-------------------
mkdir build_main
cd buid_base
cmake .. -DSET_PROF=MAIN
make
make install

-------------------
2.1.2. XEVD
-------------------
git clone git@github.com:mpeg5/xeve.git
cd xeve

-------------------
base profile
-------------------
mkdir build_base
cd buid_base
cmake .. -DSET_PROF=BASE
make
make install

-------------------
main profile
-------------------

mkdir build_main
cd buid_base
cmake .. -DSET_PROF=MAIN
make
make install

---------------------------------------
2.2. Build ffmpeg with libxeve and libxevd
---------------------------------------
It is required ffmpeg to be configfured with --enable-libxeve and --enable-
libxevd

Please find below exaple 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="$HOME/bin" \
--enable-gpl \
--enable-gnutls \
--enable-libaom \
--enable-libass \
--enable-libfdk-aac \
--enable-libfreetype \
--enable-libmp3lame \
--enable-libopus \
--enable-libdav1d \
--enable-libvorbis \
--enable-libvpx \
--enable-libx264 \
--enable-libx265 \
--enable-libxeve \
--enable-libxevd \
--enable-nonfree && \
PATH="$HOME/bin:$PATH" make -j $(nproc)

make install
