Welcome to Deflect, a C++ library for streaming pixels to other Deflect-based applications, for example Tide. Deflect offers a stable API marked with version 1.0 (for the client part).
Deflect provides the following functionality:
- Stream pixels to a remote Server from one or multiple sources
- Stream stereo images from a distributed 3D application
- Receive input events from the Server and send data to it
- Transmitted events include keyboard, mouse and multi-point touch gestures
- Compressed or uncompressed streaming
- Fast multi-threaded JPEG (de)compression using libjpeg-turbo
DeflectQt (optional) provides the following additional functionality:
- Create QML applications which render offscreen and stream and receive events via Deflect
The following applications are provided which make use of the streaming API:
- DesktopStreamer: A small utility that lets you stream your desktop.
- SimpleStreamer: A simple example to demonstrate streaming of an OpenGL application.
- QmlStreamer (optional): An offscreen application to stream any given qml file.
