# LckDescriptor

> How to read the active capture resolution, framerate, and bitrate settings from the LIV Camera Kit (LCK) SDK in Unity.

## Description

`LckDescriptor` is a wrapper around the active `CameraTrackDescriptor` that describes the current capture configuration — resolution, framerate, and bitrate. You get it from `ILckService.GetDescriptor()` to inspect what settings are being used for recording or streaming.

***

## Usage

Use `LckDescriptor` when you need to read or display the current capture settings at runtime.

```c# theme={null}
var descriptorResult = _lckService.GetDescriptor();

if (descriptorResult.Success)
{
    var descriptor = descriptorResult.Result;
    Debug.Log($"Active resolution: {descriptor.cameraTrackDescriptor.Resolution.Width}x{descriptor.cameraTrackDescriptor.Resolution.Height}");
    Debug.Log($"Active framerate: {descriptor.cameraTrackDescriptor.Framerate}");
    Debug.Log($"Active bitrate: {descriptor.cameraTrackDescriptor.Bitrate}");
}
else
{
    Debug.LogError($"Failed to retrieve descriptor: {descriptorResult.ErrorMessage}");
}
```
