Description

LckService is the central entry point for interacting with the LIV Capture Kit at runtime and the default implementation of ILckService. It provides APIs for starting and stopping recording or streaming, configuring capture settings (resolution, framerate, bitrate, orientation), managing audio, capturing photos, and controlling active cameras. This service also exposes events for key lifecycle moments (recording started, stopped, paused, resumed, streaming events, photo saved, etc.), making it easy to integrate LCK into your application workflow.

​
Usage

  • Retrieve the service via DI: 
    [InjectLck] private ILckService _lckService;
  • Configure capture options (resolution, framerate, bitrate) before starting capture.
  • Start recording or streaming with StartRecording() or StartStreaming().
  • Subscribe to public events such as OnRecordingStarted, OnStreamingStopped, or OnPhotoSaved to react to capture lifecycle changes.
