Implementation Details and Technical Considerations

Core Functionality and Methods

The core of the StreamOrchestrationService revolves around two primary methods: startStreaming(platforms[]) and stopStreaming(). The startStreaming() method initiates the streaming process, taking an array of target platforms as input. Upon receiving this input, the service orchestrates the following actions:

• Initializes the streaming session.
• Configures and connects to each specified platform.
• Activates the MediaCaptureService and SceneCompositorService to prepare the media stream.
• Utilizes the WebRTCGatewayService to facilitate real-time streaming.
• Calls the backend APIs to configure each platform's streaming settings.

The stopStreaming() method, on the other hand, gracefully concludes the streaming sessions. This process includes:

• Stopping all active streams.
• Releasing all associated resources.
• Updating the state machine to the stopped state.

These two methods encapsulate the essence of managing the streaming workflow, providing the foundation for a seamless multi-platform streaming experience. The startStreaming() method acts as a launchpad, coordinating all the necessary steps to initiate the streaming process across multiple platforms. The stopStreaming() method ensures a controlled and safe shutdown of the streaming session, releasing all allocated resources and updating the state accordingly. The implementation adheres to a state machine paradigm, providing a clear and structured approach to managing the various stages of the streaming process. The service also incorporates robust error handling, allowing it to gracefully manage partial failures, ensuring that the streaming continues on platforms that are functioning correctly, even if others experience issues.

State Management and Streaming Session Tracking

At the core of the StreamOrchestrationService is a state machine, meticulously designed to track the lifecycle of each streaming session. The state machine transitions through several distinct phases: initializing, connecting, live, stopping, and stopped. This stateful approach provides a clear and organized view of the streaming process, ensuring that the service can effectively manage and monitor the streaming sessions. The activeSession signal, of type StreamingSession, plays a crucial role in providing real-time information about the current state of the streaming session. This signal emits updates about the streaming session's status, allowing other components to react accordingly. As the streaming session progresses through the state machine, the activeSession signal reflects the current state, providing real-time insights into the streaming process. This detailed tracking system enables the service to handle various scenarios, including potential errors, and allows the platform to maintain a stable and reliable streaming environment. The implementation of the state machine incorporates robust error handling mechanisms, allowing it to respond to partial failures and ensure that streaming continues on platforms functioning correctly, even if others encounter issues.
