Get WebCamTexture at high frame rates (240 fps)

Is there any way to get WebCamTexture to get images at 240fps on Android? I am trying to get the slow-motion camera feed being pulled in to my game, but I have only been able to get at most 30FPS from the camera (not even 60).

Here is my super quick script I have used to attempt to get it working. It is showing that the WebCamTexture is updating at around 30fps, and the game is running at 60fps.

using UnityEngine;
using UnityEngine.UI;

public class WebcamTest : MonoBehaviour
{
    public RawImage m_RawImage;

    public TMPro.TMP_Text m_Text;

    private WebCamTexture m_WebCamTexture;

    private int m_NumCamUpdates;
    private int m_NumFrames;

    // Start is called before the first frame update
    void Start()
    {
        Application.targetFrameRate = 240;

        m_WebCamTexture = new WebCamTexture();
        m_WebCamTexture.requestedWidth = 1920;
        m_WebCamTexture.requestedHeight = 1080;
        m_WebCamTexture.requestedFPS = 240;
        m_WebCamTexture.Play();

        m_RawImage.texture = m_WebCamTexture;

        InvokeRepeating("TestCamFrameRate", 1f, 1f);
    }

    void TestCamFrameRate()
    {
       string _Debug = "Num frames processed this second: [" + m_NumCamUpdates + "] from frames [" + m_NumFrames + "] at [" + m_WebCamTexture.width + " x " + m_WebCamTexture.height + "]";

        m_Text.text = _Debug;
        Debug.LogError(_Debug);

        m_NumCamUpdates = 0;
        m_NumFrames = 0;
    }

    // Update is called once per frame
    void Update()
    {
        m_NumFrames++;

        if(m_WebCamTexture.didUpdateThisFrame)
        {
            m_NumCamUpdates++;
        }
    }
}

Is there something I can do to get the WebCamTexture to run higher than 30fps, ideally up at 240fps? I have tested this running on Galaxy S6, S8 and S20, and they all run at around 30fps, never any higher.

Hi there, were you able to figure this out? I am trying to connect a UVC camera on android and get over 60fps. Thank you so much
