### WebRTC streams
WebRTC enabled cameras can be used by facilitating a direct connection with the home assistant frontend. This usage requires `CameraEntityFeature.STREAM` with `frontend_stream_type` set to `StreamType.WEB_RTC`.

WebRTC enabled cameras can be used by facilitating a direct connection with the home assistant frontend. This usage requires `CameraEntityFeature.STREAM` and the integration must implement the two following methods to support native WebRTC:
- `async_handle_async_webrtc_offer`: To initialize a WebRTC stream. Any messages/errors coming in async should be forwared to the frontend with the `send_message` callback.
- `async_on_webrtc_candidate`: The frontend will call it with any candidate coming in after the offer is sent.
The following method can optionally be implemented:
- `close_webrtc_session` (Optional): The frontend will call it when the stream is closed. Can be used to clean up things.
WebRTC streams do not use the `stream` component and do not support recording.
By implementing the WebRTC methods, the frontend assumes that the camera supports only WebRTC and therefore will not fallbac to HLS.

An integration overriding this method must also implement async_on_webrtc_candidate.
Integrations can override with a native WebRTC implementation.
