UWP get live webcam video stream

I was looking into the MediaCapture class, however it doesn't seem to expose what I'm looking for. I want the live Stream from the web cam - not to record it or preview it. I'm working on the Microsoft Cognitive Services Emotion API and I want to follow this example , but instead of getting a local video stream from the file system - I want to get a Stream from a web cam. The Microsoft Cognitive Services Video APIs, including Emotion, are REST APIs, not streaming APIs, so your scenario is not supported. What you can do instead is periodically capture a frame and make RESTful calls to one of

AS3 - Webcam video dimensions not carrying over into new BitmapData - defaulting to 320x240

由 为君一笑 提交于 2019-12-01 01:57:56
I am attempting to capture a 1920x1080 webcam capture and create a new bitmap with the capture. I feel like I have all the dimension settings correct but the final 1920x1080 bitmap only contains a small 320x240 version of the video capture. Help! import flash.display.Bitmap; import flash.display.BitmapData; var bandwidth:int = 1000; // Maximum amount of bandwidth that the current outgoing video feed can use, in bytes per second. var quality:int = 100; // This value is 0-100 with 1 being the lowest quality. var cam:Camera = Camera.getCamera(); cam.setQuality(bandwidth, quality); cam.setMode

简单的Windows Webcam应用：Barcode Reader

由 不打扰是莪最后的温柔 提交于 2019-11-30 22:36:28
在Windows上用WinForm创建一个Webcam应用需要用到DirectShow。DirectShow没有提供C#的接口。如果要用C#开发，需要创建一个桥接DLL。Touchless SDK是一个免费开源的.NET库，对DirectShow进行了简单的封装。使用 Touchless 可以很方便的在WinForm应用中调用camera。这里分享下如何创建一个调用webcam的barcode reader。 参考原文： WinForm Barcode Reader with Webcam and C# 作者： Xiao Ling 翻译：yushulx WinForm Barcode Reader 下载 Touchless SDK 。 Dynamsoft Barcode Reader SDK 用于barcode识别. 如要想用免费开源的，可以选择 ZXing.NET 。 打开 Visual Studio 2015 创建一个 WinForm工程. 通过 Nuget 可以在工程中直接下载安装Dynamsoft Barcode Reader: 在引用中添加 TouchlessLib.dll : 把 WebCamLib.dll 添加到工程中。属性中设置拷贝。这样工程编译之后就会把DLL拷贝到输出目录中，不需要再手动拷贝。 初始化 Touchless 和 Dynamsoft Barcode

OpenCV 2.4.4 Java - Grab Webcam picture/stream (OSX)

由 可紊 提交于 2019-11-30 21:28:26
I'm new in the world of Stackoverflow and in OpenCV programming. I've made some projects with OpenCV Bindings for Java (the opencv.org officials, not JavaCV), like object recognition through ORB and SURF features, working with images. Everything ok. Now I'm moving to object recognition in video streams. I want to grab stream from webcam and apply object recognition. I'm not a Java guru, so I found in OpenCV the VideoCapture class, but I'm not able to obtain pictures from the camera. I'm running my project in Eclipse with OpenCV 2.4.4 bindings, in OSX Mountain Lion. The result in the console:
