that this is a problem that Unity can and should solve on their end. Software-only video sources, like the OBS Virtual Camera, do not use DevicePath. Relying on DevicePath seems to not be recommended,

OBS 27.2.1
Other software can be called, but Unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


public class WebCamManager : MonoBehaviour
{
    // Use this for initialization 
    void Start () { 
        GetWebCam();
    }

    void GetWebCam(){
        WebCamTexture webcamTexture = new WebCamTexture (); 

        #if (Unity_IOS || UNITY_ANDROID) && !UNITY_EDITOR

        for (int i = 0; i < WebCamTexture.devices.Length; i++) { 
            if (!WebCamTexture.devices [i].isFrontFacing) { 
                webcamTexture.deviceName = WebCamTexture.devices [i].name; 
                break; 
            }
        }
        #endif
        #if UNITY_EDITOR
        for (int i = 0; i < WebCamTexture.devices.Length; i++) { 
            Debug.Log(WebCamTexture.devices[i].name);
            if(WebCamTexture.devices[i].name != null){
                 webcamTexture.deviceName = WebCamTexture.devices[i].name;
            }
        }
        #endif
 
        Renderer _renderer = this.GetComponent<Renderer>(); 
        _renderer.material.mainTexture = webcamTexture; 
        webcamTexture.Play(); 
    }
}

OBS 25

I submitted it. Why can’t I find it? Do I need to go to the mailbox to confirm that it will be displayed? My email is out of service

It doesn’t work like that. After you submit your bug report:

  • you will get an email that your report is received and there will be an URL to the fogbugz page where you can check on your report
  • someone at Unity will try to recreate your bug and will decide if it is really a bug, user error or behavior by design, you will get an email about this decision
  • if it’s deemed a bug, that someone will open an issue in the issuetracker (most of the time, there are some rare cases when they only track problems internally), which will appear on the issuetracker and becomes visible for the public

Could you please resubmit the report with a working email account and a note saying that the previous report should be dismissed? QA has to be able to communicate with you in case they have follow-up questions.
