NetLibDirectshowCapture
A .NET Wrapper of libdshowcapture using .NET 8.0 C++/CLI
This is a direct wrapper, so almost all behaviors should be consistent with libdshowcapture. And it should be compatible with all the devices that OBS Studio supports.
Performance
This library is written in C++/CLI (aka. C++ Interop), which has better performance according to Microsoft. All the marshaling details are manually controlled for optimized performance and latency. The callback exposed the native pointer directly, which eliminate all of the unnecessary copies. It should has lower latency compared to other camera library using explicit P/Invoke.
Usage Example
// List all capture devices
var videoDevices = NetLibDirectshowCapture.Device.EnumVideoDevices();
var videoDevice = videoDevices[0];
// Check device's capabilities
var cap = videoDevice.Capabilities
.First(c => c.Format == VideoFormat.YUY2 && c.MaxCx == 1920 && c.MaxCy == 1080);
// Create config
VideoConfig videoConfig = new VideoConfig()
{
Name = videoDevice.Name,
Path = videoDevice.Path,
UseDefaultConfig = false,
Cx = cap.MaxCx,
CyAbs = cap.MaxCy,
CyFlip = false,
FrameInterval = cap.MinInterval,
InternalFormat = cap.Format,
Format = VideoFormat.XRGB
};
byte[] managedArray = null;
// Create frame event handler
videoConfig.OnVideoCaptured += (o, e) =>
{
managedArray ??= new byte[e.Length];
System.Runtime.InteropServices.Marshal.Copy(e.Ptr, managedArray, 0, e.Length);
// Process frames using managedArray...
};
// Run!
var device = new Device();
device.ResetGraph();
device.VideoConfiguration = videoConfig;
device.ConnectFilters();
device.Start();
