List connected cameras. CameraPlayer.

中文版文档(Chinese version)

It supports .NET Standard 2.0( and above), so it supports .NET Core 3.1 (and above) and .NET framework(above 4.6.1).

Zack.CameraLib.Core

Used for listing connected cameras(Windows-Only currently).

Step 1:

Install-Package Zack.CameraLib.Core

Step 2:

var cameras = CameraUtils.ListCameras();
foreach(CameraInfo camera in cameras)
{
	Console.WriteLine(camera.FriendlyName+","+camera.Index);
	foreach(VideoCapabilities v in camera.VideoCapabilities)
	{
		Console.WriteLine($"{v.FrameRate},{v.Height},{v.Width},{v.BitRate},{v.FrameRate}");
	}
}

Zack.WinFormCoreCameraPlayer

A .NET Core WinForm control used for displaying video of camera. Sample code of WinForm for .NET Core.

Step 1:

Install-Package  Zack.WinFormCoreCameraPlayer

Step 2:

Add a CameraPlayer to a form.

Due to a possible bug of Visual Studio, a CameraPlayer instance in the InitializeComponent may lead to error during design time. If this bug happens, please add the CameraPlayer instance by code. for example:

        private CameraPlayer player;
        public Form1()
        {
            InitializeComponent();

            this.player = new CameraPlayer();
			this.player.Location = new System.Drawing.Point(0, 0);
            this.player.Dock = DockStyle.Fill;
            this.Controls.Add(this.player);
		}

Step 3:

cameraPlayer.Start(0, new System.Drawing.Size(1024, 768));

The first parameter of Start is the index of selected camera. All the connected cameras can be listed using CameraUtils.ListCameras() of Zack.CameraLib.Core mentioned above.

If a filter is set using the method SetFrameFilter() of CameraPlayer, the Image can be processed before the Mat is rendered. OpenCVSharp can be used to process the Mat.

Sample code:

cameraPlayer.SetFrameFilter(srcMat=> {
	Cv2.Blur(srcMat, srcMat, new Size(10, 10));
});

WinFormCoreDemo1 is the sample project.

Zack.WinFormCameraPlayer

This is the .NET framework version of Zack.WinFormCoreCameraPlayer.

All the code of this .NET framework version is the same as the .NET core version, so they won't be covered here. The only difference is the NuGet package name is Zack.WinFormCameraPlayer

WinFormDemo1 is the sample project.
