JavaScript classes for capturing images from camera in web application

Each modern web browser provides the "navigator.mediaDevices" property that returns a "MediaDevices" object, which provides an entry point to connected media input devices such as cameras. Internet contains many code samples, which demonstrate how to work with camera in JavaScript code. VintaSoft created own helper-classes, which simplify working with media devices in web application.

Demo application "VintaSoft ASP.NET Core Camera Demo" contains classes, which simplify working with media devices in web application:

• VideoInputDeviceManagerJS - JavaScript class that allows to get the list of available media devices, refresh list of available media devices, get media device by identifier.
• VideoInputDeviceJS - JavaScript class that allows to get device information, start/stop video playing, activate/deactivate the media stream of device, capture video frame from device, close the device.
• WebcamDialogJS - JavaScript VintaSoft UI-dialog that allows to capture images from the camera.

Functionality of classes (VideoInputDeviceManagerJS, VideoInputDeviceJS, WebcamDialogJS) can be tested using on-line demo application "VintaSoft ASP.NET Core Camera Demo".

Source codes of classes (VideoInputDeviceManagerJS, VideoInputDeviceJS, WebcamDialogJS) are available in source codes of demo application "VintaSoft ASP.NET Core Camera Demo" and can be get on Github or in installation of evaluation version of VintaSoft Imaging .NET SDK in folder "<SdkInstallPath>\VintaSoft\Imaging .NET 15.0\Examples\ASP.NET Core\CSharp\AspNetCoreCameraDemo\".
