This commit adds the framework APIs, editor and rendering features needed to support live streaming. Along with this, we're working on a new plugin that adds Twitch.tv support (waiting for legal approval to commit.)
- Game live streaming
- Allows general support for live internet streaming of game video and audio
- Web cam video feed can be overlaid onto game viewports automatically
- New 'Broadcast' Blueprint function library allows you to easily start broadcasting from your game
- New IGameLiveStreaming API that allows you to start broadcasting through C++
- Editor live streaming
- The editor UI now displays a "broadcast" button automatically when a live streaming service is available
- Broadcasting of all desktop editor windows is supported (configured in preferences)
- If you have a web cam, video will be displayed automatically while broadcasting in a new editor window
- New "Live Streaming" editor preference tab with many new settings for configuring broadcasting
- New IEditorLiveStreaming API that lets you control editor broadcasting directly, if needed
- Added new 'Broadcast.Start' and 'Broadcast.Stop' console commands
- These allow you to easily test live streaming in games without writing UI code
- Built-in help is available for these new commands
- To implement a live streaming plugin:
- Inherit from the new ILiveStreamingService interface
- Register your "LiveStreaming" feature with the IModularFeatures system
- Other changes:
- Eliminated broken screen quad drawing functions; replaced with publicly-exposed DrawRectangle()
- Slate: Eliminated legacy code for 'marking windows as drawn' (not used anymore)
- Slate: Added Slate rendering callback to find out when a frame buffer is ready to be presented
