NDI-EMBER-MTX

NDI Matrice with Ember control for NDI - VSM integration The NDI MTX creates virtual targets (defined in target.json file) that you can select from your NDI Decoder (E.g. vMix or a Birddog)

It's build with static installations in mind, so it's not using discovering protocol for finding sources. But instead a static list in sources.json file.

Matrix view:

Client Panel view:

Installation:

(ubuntu 20.04lts on Intel based machine)

Setup in storage folder:

sources.json is the list of sources remember to add dnsName AND url targets.json is the name of targets, you can add up to 100 in current configuration.

Build and run:

ndi_mtx.cc will build when yarn is called. (c compiler on machine is needed)

apt-get update && apt-get install -y libavahi-common-dev libavahi-client-dev build-essential
clone and cd to ndi-ember-mtx folder
install nodejs and yarn
cp ./lib/x86_64-linux-gnu/* /usr/lib/
yarn
yarn build-server
yarn build-client
yarn start

Open MTX GUI in chrome:

http://localhost:3008

Open CLIENT PANEL GUI in chrome:

http://localhost:3008/?target=2

Connect to Ember server on port: 9000

REST API

You can change connections from REST API with:

POST http://localhost:3008/setmatrix?source=8&target=3

And /state returns JSON with current state:

http://localhost:3008/state

Example of autostart using systemd:

(based on standard install of nodejs and user named ndi)

create start.sh file in ndi-ember-mtx folder:

#!/bin/bash
while true; do
    echo "Starting NDI MTX"
    cd /home/ndi/ndi-ember-mtx
    /etc/bin/node build/server/index.js
    sleep 2
done

create systemd service file /etc/systemd/system/ndimtx.service
