The frontend and web server elements for Unreal Pixel Streaming (previously located in Samples/PixelStreaming/WebServers
) are now in this repository, for all to contribute to. They are referred to as the Pixel Streaming Infrastructure.
The goals of this repository are to:
- Increase the release cadence for the Pixel Streaming servers (to mitigate browser breaking changes sooner).
- Encourage easier contribution of these components by Unreal Engine licensees.
- Facilitate a more standard web release mechanism.
- Grant a permissive license to distribute and modify this code wherever you see fit (MIT licensed).
If you would like to contribute to our repository, please reference our contribution guide. Thank you for your time and your efforts!
The Pixel Streaming Infrastructure contains reference implementations for all the components needed to run a pixel streaming application. They are structured as separate projects, which work together, but are designed to be modular and interoperable with other implementations which use WebRTC technology. These implementations include:
-
A signalling web server, called Cirrus, found in
SignallingWebServer/
. -
An SFU (Selective Forwarding Unit), found in
SFU/
. -
A matchmaker, found in
Matchmaker/
. -
Several frontend projects for the WebRTC player and input, found in
Frontend/
:- shared libraries for communication and UI functionality
- separate implementations using different technologies such as TypeScript or React/JSX
For detailed information, see the /frontend.
We release a number of different components under this repository, specifically:
- Container images for the signalling server
- NPM packages for the frontend
- Source releases of this repo with the reference frontend built as a minified js bundle
The following container images are built from this repository:
The following are unofficial
NPM packages (official ones coming soon):
