Enumerating the video capture devices with DirectShow works well in console but does not work with Unity...












0














I use Unity 2018.2.12 and DirectShow.Net



I created simple code that enumerates video capture devices. It founds devices but it cannot obtain their FriendlyName property under being running as Unity script.



using DirectShowLib;
using UnityEngine;

namespace DirectShow.Net_Tests {
public class CodeForUnity : MonoBehaviour {

void Start() {
foreach (var device in DsDevice.GetDevicesOfCat(FilterCategory.VideoInputDevice))
{
Debug.Log(
$"Device Name:t{device.Name}n" +
$"tDevice FriendlyName (Property):t{device.GetPropBagValue("FriendlyName")}n" +
$"tDevice Class GUID:t{device.ClassID}n");
}
}
}
}


The same code can obtain FriendlyName property being running as console application.



using System;
using DirectShowLib;

namespace DirectShow.Net_Tests {
static class Program {

public static void Main(string args) {
foreach (var device in DsDevice.GetDevicesOfCat(FilterCategory.VideoInputDevice))
{
Console.WriteLine(
$"Device Name:t{device.Name}n" +
$"tDevice FriendlyName (Property):t{device.GetPropBagValue("FriendlyName")}n" +
$"tDevice Class GUID:t{device.ClassID}n");
}
}
}
}


Why does not it work in Unity?

  • @VuVirt This function outputs a string to the console in Unity. What could be the problem?
