# Play video file

You can play VVC video codec with .h266, .vvc, .266 and anything or .mp4 muxed with VVC codec:

```
ffplay_vvceasy versatile.266
```

Or if you have xHE-AAC audio codec:

```
ffplay_vvceasy -codec:a libfdk_aac -i versatile.m4a
```

# Limitations of FFmpeg VVC encoder

Before encode to VVC video codec, see the limitations below.

libvvenc (FFmpeg vvc version) works for:

- Pixel format ✅ (changeable of 8/10bit) 
- Video size (auto detects, but it doesn't detect for SAR and DAR anamorphic is glitch and corrupts the video ) ⚠️ (Better way to use vvencapp without FFmpeg)
- Frame rate ✅ (auto detects) 
- MP4 Muxing :x: (does not support, you need MP4BOX after encode.)
- Audio with encode VVC ⚠️ (does not support, because it can corrupt the file) To avoid corrupt file, you need to disable audio using `-an` or you could do output container for .266, .vvc and .h266 too.
- Bitrates ✅
- Passes ⚠️ (only one pass)
- Presets ⚠️ (only medium preset)
- QP/CRF ⚠️ (only you can set -global_quality command only, global_quality equals qp)
- HDR ⚠️ (default SDR, but cannot encode HDR)

Built in libvvenc for FFmpeg command:

```
ffmpeg -i example.mp4 -c:v libvvenc -global_quality 37 -pix_fmt yuv420p10 example.266
```

Additional command: You can convert to vvc video without taking a much space for vvencapp, example:

```
ffmpeg -i example.mp4 -pix_fmt yuv420p -f yuv4mpegpipe - | vvencapp --y4m -i - --preset medium --qp 35 -o converted.266
```

Converting xHE-AAC to AAC audio:

```
ffmpeg -c:a libfdk_aac -i mymusic.m4a -c:a aac -b:a 128k mymusic.aac
```

Replace video size for `-s` and frame rate for `-r`.

### Update 21th May 2022 of FFmpeg vvdec support

Good news, you can play .mp4 file after .h266 and audio format were merged into mp4 playable of VVC.

About [xHE-AAC](https://www.iis.fraunhofer.de/en/ff/amm/broadcast-streaming/xheaac.html), now it's available decode support xHE-AAC of FFmpeg. [Exhale](https://gitlab.com/ecodis/exhale) (encoder) is free to use and open source, but if you want Fraunhofer IIS xHE-AAC, you can download [EZ CD Audio Converter](https://www.poikosoft.com/music-converter) for Windows only. You can also merge your encoded xHE-AAC audio into mp4 too.

To make playable mp4 with audio and video together, you need VVC video encoded, audio file and [GPAC Nightly build](https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/). Code for mp4box/gpac to merge VVC video encoded and audio file:
```
mp4box -add video.266 -add audio.m4a -new convertedvvc.mp4
```

Containers are also acceptable video containers of .mkv, .mp4, .mov and more.

For Linux and Mac OS users: Replace **mp4box** by **gpac**

### Note about downloads

I use always Windows to compile FFmpeg, so I forgot compile every time for Mac OS and Linux. Also, please check changelog before you download the new version.

```

# Mac OS downloaders (Important note)

Please note, this is not a malware of my compiled build, see the three screenshots to make run ffmpeg tools customised version

You need to allow the app on your Mac OS for chmod write access & Security & Privacy:

Step 1: Click cancel button, do not move to bin.

### Build Mac OS for FFmpeg VVC build

Requirements:

Xcode

CMake

NASM

Homebrew

Code to build FFmpeg VVC version:

```
brew install libxml2 ffmpeg fdk-aac nasm
git clone https://github.com/fraunhoferhhi/vvenc
git clone https://github.com/fraunhoferhhi/vvdec
cd vvenc && mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
sudo cmake --build . --target install -j $nproc
cd ../../
cd vvdec && mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
sudo cmake --build . --target install -j $nproc
cd ../../
git clone --depth=1 https://github.com/MartinEesmaa/FFmpeg-FixVVC
cd FFmpeg-FixVVC
./configure --enable-libfdk-aac --enable-libvvenc --enable-libvvdec --enable-static --enable-pic --enable-libxml2 --pkg-config-flags="--static" --enable-sdl2
make -j
```

# Linux builders (Important for FFplay)

You can build using this:

```
sudo apt update && sudo apt upgrade -y && \
sudo apt install build-essential cmake nasm autoconf pkg-config \
python3-setuptools ninja-build python3-pip libtool git wget -y && \
sudo pip3 install meson && \
git clone --depth=1 https://github.com/fraunhoferhhi/vvenc && \
git clone --depth=1 https://github.com/fraunhoferhhi/vvdec && \
git clone --depth=1 https://github.com/mstorsjo/fdk-aac && \
git clone --depth=1 https://github.com/libsdl-org/SDL && \
git clone --depth=1 https://github.com/gnome/libxml2 && \
git clone --depth=1 https://github.com/xiph/opus && \
git clone --depth=1 https://code.videolan.org/videolan/dav1d && \
git clone --depth=1 https://github.com/MartinEesmaa/FFmpeg-FixVVC && \
cd vvenc && sudo make install-release install-prefix=/usr/local disable-lto=1 && \
cd .. && \
cd vvdec && sudo make install-release install-prefix=/usr/local disable-lto=1 && \
cd .. && \
cd fdk-aac && autoreconf -if && ./configure --prefix=/usr/local --enable-static --disable-shared && sudo make install -j $nproc && \
cd .. && \
cd libxml2 && autoreconf -if && ./configure --prefix=/usr/local --enable-static --disable-shared && sudo make install -j $nproc && \
cd .. && \
cd opus && autoreconf -if && ./configure --prefix=/usr/local --enable-static --disable-shared && sudo make install -j $nproc && \
cd .. && \
cd SDL && ./configure --prefix=/usr/local --enable-static --disable-shared && sudo make install -j $nproc && \
cd .. && \
mkdir dav1d/build && cd dav1d/build && meson -Denable_docs=false -Ddefault_library=static -Dprefix=/usr/local .. && sudo ninja install && \
cd ../../ && \
cd FFmpeg-FixVVC && \
./configure --enable-static --pkg-config-flags="--static" --extra-ldexeflags="-static" \
--enable-libfdk-aac --enable-libvvenc --enable-libvvdec --enable-pic \
--enable-libxml2 --enable-libopus --enable-libdav1d --enable-sdl2 && \
make -j
```

If you want actually play VVC file with FFplay on your local distro, you need to remove command `--extra-ldexeflags="-static"`, otherwise it might give result segmentation fault for FFplay static only.

If compiling is success and finished, you can install FFmpeg VVC for using the code:

```
mv ffmpeg ffmpeg_vvceasy
mv ffplay ffplay_vvceasy
mv ffprobe ffprobe_vvceasy
sudo cp ffmpeg_vvceasy ffplay_vvceasy ffprobe_vvceasy /usr/local/bin
```
