pyatem 0.10.0

Installation

Install the pyatem protocol module:

setup.py build
sudo setup.py install

Build and install the gtk application and proxy:

meson build
meson compile -C build
sudo meson install -C build

Run the application:

switcher-control

There is also the openswitcher-install.sh script which will install the library, proxy and gtk application in /usr/local for a quick installation of all components.

External dependencies

The only external dependency for pyatem is pyusb for the USB protocol support. It contains a native compiled module so it also requires a toolchain and python-dev headers at build time.

OpenSwitcher depends on the python bindings from gtk3.

OpenSwitcher-proxy only depends on pyatem for the core functionality but it might need more dependencies when loading specific frontends or backends:

• MQTT Frontend: paho-mqtt

Developing

To work on the pyatem library the quickest way to get up and running is using the openswitcher-develop.sh script that will install the pyatem library in devel mode where the files are symlinked to the git repository. It will also install the proxy and gtk application in /usr/local which will use the symlinked library.

Development happens on matrix on #openatem:brixit.nl

Proxy

There is also the openswitcher_proxy python module in this repository. It will run an API wrapper around one or more ATEM switchers. There is currently a single api supported which is a HTTP REST api for sending commands and reading the mixer state.

It can be run by starting the module:

python3 -m openswitcher_proxy --config /etc/myconfigfile.toml

Or if the software installed it can be started using the launcher script:

openswitcher-proxy --config /etc/myconfigfile.toml

The default config location is /etc/openswitcher/proxy.toml if not specified. Here’s an example config:

[[hardware]] id = “mini” label = “Atem Mini” address = “192.168.2.84”

[[hardware]] id = “mini2” label = “Local switcher” address = “usb”

[[frontend]] type = “http-api” bind = “:8080” auth = true username = “bob” password = “hunter2” hardware = “mini,mini2”

[[frontend]] type = “status” bind = “127.0.0.1:8082” auth = false

The status frontend provides a simple html page with the state of the connected switchers and a list of the enabled frontends.

The http-api frontend provides a HTTP server that can return any of the supported fields as json and trigger commands by sending a HTTP POST request with formfields or json
