GUI based Reciever - transmitter - transcoder for video and audio
Livefactory is build with containerbased production in mind.
So instead of including ffmpeg inside the code, ffmeg runs an instance pr. Transcoder.
You can run a local ffmpeg instance or use the docker API for controlling other machines (nodes https://docs.docker.com/engine/api/v1.43/)
It's using the dockerode package for handling this (https://www.npmjs.com/package/dockerode)
Roadmap:
- SDP support
- Refactor rest of the "ffmpeg command" command handling to backend, prior to API integration
- Build Pipeline
- REST API for external control
- 2110 Decklink IP card support
- NMOS support
- GUI refining
- A dockerbased ffmpeg engine with NDI and RIST support (in progress, but due to licence issues this might not be open sources)
Following input/output is supported
SRT, File, NDI, Decklink (SDI), Mpeg-ts, Colorbar, UDP, TCP, RTP
SRT, NDI, Decklink (SDI), Mpeg-ts, Screen, TCP, RTP
COPY is the settings when output to NDI, Decklink, Screen etc.
For transport of h264/265 following options is available: H264_NATIVE , HEVC_NATIVE, H264_MAC, HEVC_MAC, H264_NVIDIA, HEVC_NVIDIA
In input and/or output a custom option is available, this is for adding custom ffmpeg commands.
Install git, node and yarn on your machine.
git clone https://github.com/olzzon/live-factory
cd live-factory
yarn
yarn build
yarn start
Open GUI in browser:
http://localhost:1406
When running Live-factory for the first time, live-factory/settings.json folder and file will be created in your home folder, with all the available options. Depening on the setup, it's possible to remove certain types from the allowed lists. An example of the settings.json file is placed in: Doc/settings.json
Here's the basic structure of the settings.json file:
{
"maxActiveEncoders": 1,
"nodeList": [
{
"name": "FFmpeg local",
"type": "FFMPEG",
"path": "/opt/homebrew/bin/ffmpeg",
"hwaccel": "NONE"
},
{
"name": "Docker Node 01",
"type": "DOCKER",
"host": "192.168.1.119",
"port": 4244,
"containerName": "jrottenberg/ffmpeg",
"hwaccel": "NONE",
"mapHostFolders": ["/tmp:/tmp"]
},
{

}

{
"value": "COLORBAR",
"label": "COLORBAR"
},
{

"label": "COPY"

"label": "H264_NATIVE"
},
..................................
]
}
This example is on Ubuntu:
nano /lib/systemd/system/docker.service
Find the line which starts with ExecStart and adds -H=tcp://0.0.0.0:2375 to make it look like ExecStart=/usr/bin/dockerd -H=fd:// -H=tcp://0.0.0.0:4333
systemctl daemon-reload
sudo service docker restart
Test if it is working by using this command, if everything is fine below command should return a JSON
curl http://localhost:4333/images/json
```

### Build FFMPEG
Follow https://trac.ffmpeg.org/wiki/CompilationGuide/macOS
Add dependencies:

brew install automake fdk-aac git lame libass libtool libvorbis libvpx opus sdl shtool texi2html theora wget x264 x265 xvid nasm librist
```
```
install: http://new.tk/NDIRedistV5Apple
```
#### Clone FFMPEG-NDI repository:
```
https://github.com/olzzon/ffmpeg-ndi
```
### Make compilation static??? ToDO!!!:
https://video.stackexchange.com/questions/14717/how-to-compile-ffmpeg-with-libfdkaac-into-a-single-static-binary
!Remove all *.dylib in /usr/local/lib
### Configure
```
make distclean
???? --enable-librist
NO LIBRIST INSTALL ON OTHER MACHINES:
./configure --prefix="$HOME/coding/ffmpeg/build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/coding/ffmpeg/include --static" --enable-libsrt --enable-shared --enable-static --enable-gpl --extra-version=olzzon --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libopus --samples=fate-suite --enable-videotoolbox --enable-libndi_newtek --enable-decklink --disable-ffplay --disable-doc
```
```
make -j10
sudo make install
```
Rename ffmpeg to ffmpegruntime and copy it to "$HOME/live-factory" folder
# Build FFmpeg Ubuntu x86
## Install TeamViewer AFTER adding dependencies
### Get dependencies:
```
# These two had problems when installed later:
sudo apt install libsdl2-dev libass-dev
sudo apt update -qq && sudo apt -y install autoconf automake build-essential cmake git libssl-dev libfreetype6-dev libgnutls28-dev libmp3lame-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev meson ninja-build pkg-config texinfo wget yasm zlib1g-dev libunistring-dev libaom-dev nasm libx264-dev libx265-dev libnuma-dev libvpx-dev libfdk-aac-dev libopus-dev nvidia-cuda-toolkit
```
Install NVidia driver:
```
sudo ubuntu-drivers autoinstall
```
### Get source and set path:
```
mkdir ~/bin
cd ~
git clone https://github.com/olzzon/ffmpeg-ndi.git
cd ffmpeg-ndi
PATH="$HOME/bin:$PATH"
PKG_CONFIG_PATH="$HOME/ffmpeg-ndi/lib/pkgconfig"
```
### Set lib path
Set default PATH:
```
nano ~/.bashrc
ADD:
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/lib:/usr/lib/"
```
### Install Decklink:
install both Software AND SDK from blackmagicdesign.com
```
copy SDK lib files to ffmpeg-ndi/include
```
### Install NDI SDK:
https://downloads.ndi.tv/SDK/NDI_SDK_Linux/Install_NDI_SDK_v5_Linux.tar.gz
unpack with GUI
copy x86 libndi.so files to ffmpeg-ndi/lib
(HACK: extract SDK and move the libndi.so.5 files to /usr/lib, it's important to move not copy as a cp will creat a new symbolic link for one of the files)
### Compile SRT:
```
cd ~/ffmpeg-ndi
git clone --depth 1 https://github.com/Haivision/srt.git
mkdir srt/build
cd ~/ffmpeg-ndi/srt/build
cmake -DENABLE_C_DEPS=ON -DENABLE_SHARED=ON -DENABLE_STATIC=OFF -fPIC ..
make
sudo make install
```
### Compile CUDA support:
```
cd ~/ffmpeg-ndi
git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
cd nv-codec-headers && sudo make install && cd ..
### Prepare and compile:
```
cd ~/ffmpeg-ndi
./configure --prefix="$HOME/ffmpeg-ndi" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg-ndi/include -I/usr/local/cuda/include" --extra-ldflags="-L/usr/local/cuda/lib64 -L$HOME/ffmpeg-ndi/lib" --extra-libs="-lpthread -lm" --ld="g++" --bindir="$HOME/bin" --enable-libsrt --enable-gpl --enable-gnutls --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libopus --samples=fate-suite --enable-libndi_newtek --enable-decklink --enable-nvenc --enable-librist
??? --enable-cuda --enable-cuvid --enable-nvdec --enable-nvenc
make
sudo make install
export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib/:/home/ubuntu/ffmpeg-ndi/lib
source ~/.profile
```
Rebuild remember:
```
make distclean
