### OpenSeeLauncher Component API

Source: https://github.com/emilianavt/openseeface/blob/master/README.md

The OpenSeeLauncher component in Unity allows for starting, stopping, and managing the face tracker executable directly from within the Unity application.

```APIDOC
## OpenSeeLauncher Component API

### Description
Provides functions to control the OpenSeeFace tracker executable from Unity.

### Methods

* `public string[] ListCameras()`
  * **Description**: Returns the names of available cameras. The index of the camera in the array corresponds to its ID for the `cameraIndex` field. Setting the `cameraIndex` to `-1` will disable webcam capturing.

* `public bool StartTracker()`
  * **Description**: Starts the face tracker. If it is already running, it will shut down the running instance and start a new one with the current settings.

* `public void StopTracker()`
  * **Description**: Stops the face tracker. The tracker is stopped automatically when the application is terminated or the `OpenSeeLauncher` object is destroyed.

### Additional Settings

* `commandlineArguments` (string array)
  * **Description**: Additional custom commandline arguments for the tracker. Each argument should be a separate element in the array. For example, `-v 1` should be added as two elements: `"-v"` and `"1"`.
```

--------------------------------

### OpenSeeLauncher: Adding Custom Commandline Arguments

Source: https://github.com/emilianavt/openseeface/blob/master/README.md

Additional custom commandline arguments should be added one by one into elements of commandlineArguments array. For example -v 1 should be added as two elements, one element containing -v and one containing 1, not a single one containing both parts.

```csharp
commandlineArguments

```

--------------------------------

### Run Facetracker with Visualization and Video Input

Source: https://github.com/emilianavt/openseeface/blob/master/README.md

A simple demonstration can be achieved by running the face tracker on a video file with specific visualization and tracking parameters.

```bash
python facetracker.py --visualize 3 --pnp-points 1 --max-threads 4 -c video.mp4
```

--------------------------------

### Show Help for Facetracker Script

Source: https://github.com/emilianavt/openseeface/blob/master/README.md
