Using C# Windows 10 is it possible to tell if the video/camera is currently in use by any app?
In C# on Windows 10, you can check if the camera is currently being used by any application by utilizing the MediaCaputure
API in the Windows Runtime. Here's an example:
csharpusing System;
using Windows.Devices.Enumeration;
using Windows.Media.Capture;
public class CameraUsageChecker
{
public static async Task<bool> IsCameraInUse()
{
var devices = await DeviceInformation.FindAllAsync(DeviceClass.VideoCapture);
foreach (var device in devices)
{
var mediaCapture = new MediaCapture();
var settings = new MediaCaptureInitializationSettings { VideoDeviceId = device.Id };
try
{
await mediaCapture.InitializeAsync(settings);
// The camera is available and not in use by any app
mediaCapture.Dispose();
return false;
}
catch (UnauthorizedAccessException)
{
// The camera is in use by another app
mediaCapture.Dispose();
return true;
}
}
// No camera device found
return false;
}
}
In this code, the IsCameraInUse
method checks for all available video capture devices and attempts to initialize a MediaCapture
instance for each device. If the initialization is successful, it means the camera is available and not in use by any app. If it throws an UnauthorizedAccessException
, it means the camera is already in use by another application.
To use this code, you need to add a reference to the Windows.Media.Capture
namespace in your project. Note that this code requires the Windows 10 SDK
to be installed.
By calling the IsCameraInUse
method, you can determine if the camera is currently in use by any application on a Windows 10 system.
