Auteur

The current scope of this project is that of a basic live node compositor, with a service exposing a JSON API for creating, connecting, inspecting, scheduling and removing GStreamer processing nodes (sources, mixers and destinations as of writing).

It can be used for things like linear video feeds that allow hotswapping inputs/sources and compositing them based on a schedule (cue time and duration). As well as fail-over to backup content when a source is unavailable.

An example client running commands one at a time is provided for exploring that API.

Environment

This project depends on:

  • Rust (stable channel)

  • GStreamer (master as of writing)

  • gst-plugins-rs (master as of writing)

The most convenient testing platform for this PoC is a Linux machine, <#404>, enter a devenv then build <#404> and export GST_PLUGIN_PATH:

A few GStreamer plugins are needed, make sure to install the dependencies for all of those before building gst-build:

Building

Running

Run the service:

Explore and test the API with the client:

You can also find the API definition in common/src/controller.rs.

In addition, a simple wrapper script around the controller can be found in scripts/node_schedule.py, alongside other scripts that leverage it to demonstrate other features (eg scripts/crossfade.py)
