E2 Client, Tally system. Web UI with Presets.

Pre-built release packages can be found under the Releases.

Please refer to the Wiki for more detailed documentation, including development and feature guides.

You can also try submitting a GitHub Issue for support, which may or may not receive an answer.

Supported Devices

This implementation has been tested with the following device software versions:

  • E2 version 3.2
  • S3 version 3.2

This implementation supports the following device APIs:

  • TCP port 9876 XML (read-only, live streaming)
  • TCP port 9999 JSON-RPC (read-mostly, includes preset recall)
  • TCP port 9878 "telnet" (write-only, preset recalls and program cut/autotrans)
  • UDP port 40961 discovery

Install

Docker

Docker images for amd64 are available from Docker Hub: https://hub.docker.com/r/qmsk/e2/

docker pull qmsk/e2
docker run --rm --net=host --name=e2-test qmsk/e2 tally --discovery-interface=eth0 --http-listen=127.0.0.1:8001 --http-static=/opt/qmsk-e2/static

Raspberry PI

Pre-built debian packages for ARM are available from GitHub releases: https://github.com/qmsk/e2/releases

wget https://github.com/qmsk/e2/releases/download/v0.6.0-dev.5/qmsk-e2_0.6.0-dev.5_armhf.deb
sudo dpkg -i qmsk-e2_0.6.0-dev.5_armhf.deb
sudo edit /etc/default/qmsk-e2-tally
sudo systemctl restart qmsk-e2-tally

The package installs the binaries at /opt/qmsk-e2, creates a qmsk-e2 user and configures the systemd qmsk-e2-tally.service to run using /etc/default/qmsk-e2-tally for configuration.

Building

The project consists of a set Go applications, and a Javascript web frontend. Once built, the binary Go applications + Javascript assets can be distributed and executed without needing to install the development tools and instructions listed here.

Release binaries are built using the Docker-based setup under build

Backend

go get github.com/qmsk/e2/cmd/...

Building the backend code requires Go version 1.10.

The Go binaries can also be cross-compiled for different platforms, such as building Linux ARM binaries on your laptop for use on a RaspberryPI:

GOOS=linux GOARCH=arm go build -o bin/linux_arm/server -v github.com/qmsk/e2/cmd/server

Frontend

cd static && npm install

Building the frontend code requires:

Tally

Tally implementation for following the state of inputs on program, preview and active destinations.

Sources

Supports the following input sources:

  • E2
  • S3

Drivers

Supports the following output drivers:

Usage

Run the tally software using a network interface connected to the same network as the E2 device:

$GOPATH/bin/tally --discovery-interface=eth0

Tag the relevant inputs in EMTS with tally=ID in their Contact details field:

EMTS Contact field

Referr to the Wiki for further documentation.

Server

Web API + frontend for following the E2 state and controlling presets.

server --discovery-interface=eth0 --http-listen=:8284 --http-static=./static

The server will connect to the first discovered E2 system.

Server Presets UI

Using the server Web UI requires the static assets for the web frontend (see Building).

Referr to the Wiki for further documentation.

Client

go install ./cmd/client

Useful for testing the client library:

$GOPATH/bin/client --e2-address=192.168.0.100 listen

Usage:

  client [OPTIONS] <command>

E2 JSON-RPC:
	  --e2-address=HOST
	  --e2-jsonrpc-port=PORT
	  --e2-xml-port=PORT
	  --e2-timeout=
