[yangchar]

1. follow the steps to build ffmpeg FFMPEGVVC.md
2. ffplay_g vvc_8b_bt709-ClosedGOP-3840x2160-24fps-60s-4Mbps.mp4
3. how to get the streams
4. i did't enable-libxml2 because configure ERROR: libxml-2.0 not found using pkg-config

Hi @yangchar, I looked your number steps.

You have to click link build script in FFMPEGVVC.md.

Make sure your libxml2 is installed on your computer example (/usr/local). I recommend if you want to install correctly on your machine. Here's a short code of installation libxml2 on Linux machine:

git clone --depth=1 https://github.com/gnome/libxml2
cd libxml2
autoreconf -if
./configure --prefix=/usr/local --enable-static --disable-shared
sudo make install -j $nproc

or you can install on Ubuntu package:

sudo apt install libxml2-dev

libxml2 requires for DASH streams to demux and play a sample VVC video with seperate AAC audio file, maybe GOP Closed video.

If you have any question or issues, feel free to reply with me. :)

Thank you!

Hi Martin Can you upload ffmpeg&ffplay binary files for linux ubuntu? i can't build success; Or you can send email to me, thank you. lsb_release -a LSB Version: core-11.1.0ubuntu2-noarch:printing-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch Distributor ID: Ubuntu Description: Ubuntu 20.04.6 LTS Release: 20.04 Codename: focal

Hi @yangchar, I can build Linux static of FFmpeg for later, but libjxl, you can see the message in CMake log following like this:

You can run
/home/cambricon/ffmpeg-vvc/libjxl/deps.sh to download this dependency.

Make sure if that any case to get Ubuntu package:

sudo apt install libbrotli-dev

I'll make easy little bit for you, here is a quick libjxl build, making sure case is installed packages:

sudo apt install build-essential cmake nasm autoconf pkg-config \
python3-setuptools ninja-build python3-pip libtool git wget xxd -y && \
sudo pip3 install meson
git clone --depth=1 https://github.com/libjxl/libjxl
sed -i 's/-lm/-lm -lstdc++/g' libjxl/lib/jxl/libjxl.pc.in libjxl/lib/threads/libjxl_threads.pc.in
git -C libjxl submodule update --init --recursive --depth 1 --recommend-shallow
mkdir libjxl/build
cd libjxl/build
cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=OFF -DBUILD_SHARED_LIBS=OFF \
-DJPEGXL_ENABLE_BENCHMARK=OFF -DJPEGXL_ENABLE_PLUGINS=ON \
-DJPEGXL_ENABLE_MANPAGES=OFF -DJPEGXL_FORCE_SYSTEM_BROTLI=ON \
-DJPEGXL_FORCE_SYSTEM_GTEST=ON -DCMAKE_INSTALL_PREFIX=$PREFIX .. -G Ninja
sudo ninja install
cd ../../

While I'm busy, you can have a look my Linux build script: https://github.com/MartinEesmaa/VVCEasy/blob/master/libvvdecffmpeg.sh

And of my FFmpeg Btbn forked repository, but you have to build image first of nonfree target and then FFmpeg nonfree: https://github.com/MartinEesmaa/FFmpeg-Builds
