OBSWebRTCBridge

OBS WebRTC Bridge will create a new PeerConnectionFactory, creates a new PeerConnection, gets the OBS audio and video sources.

Basic Implementations:

  • The above code stacks define a class RTCObsBridge that has two main functions: Start() and Stop().
  • The Start() function
    • Creates a new PeerConnectionFactory,
    • Creates a new PeerConnection,
    • Gets the OBS audio and video sources,
    • Creates media streams,
    • Adds the audio and video tracks to the media stream,
    • Adds the media stream to the PeerConnection,
    • Creates an RTCOfferDescription and
    • Sets up callbacks for OBS audio and video data and start the OBS audio and video sources.
  • The Stop() function stops the OBS audio and video sources, closes the PeerConnection and releases the PeerConnectionFactory.

This is a simplified example, it is highly recommended to use a signalling protocol such as SDP to establish the connection between OBS and the WebRTC endpoint. Please keep in mind that this is a simplified example and there may be additional error handling and other code that would be needed for a production implementation.

Basic Understanding:

I can give you an idea of how you could proceed with integrating the WebRTC code into OBS Studio;

  • You would need to include the OBS Studio headers in your program, in order to use its APIs and callbacks.
  • You would need to create an OBS output module by implementing the obs_output_info struct and its required functions, such as obs_output_create, obs_output_start, obs_output_stop, and obs_output_destroy.
  • In the obs_output_create function, you would need to create an instance of the RTCObsBridge class, and initialize it.
  • In the obs_output_start function, you would need to call the Start method of the RTCObsBridge instance, to start the WebRTC connection and the OBS audio and video sources.
  • In the obs_output_stop function, you would need to call the Stop method of the RTCObsBridge instance, to stop the WebRTC connection and the OBS audio and video sources.
  • In the obs_output_destroy function, you would need to destroy the RTCObsBridge instance.
  • You would need to handle the WebRTC signaling, to establish the connection with the remote peer, and exchange the necessary information to start the video and audio streaming.
  • You would need to register the output module in the OBS Studio's plugin system, so that it can be used in the user interface.
  • It is important to note that this is just a high level idea and it will require more effort and knowledge to complete the integration. Also, it's depend on the specific use case and requirements you have.
