How to capture frames from a webcam with SharpDX

由 拟墨画扇 提交于 2020-06-17 13:25:27
问题 I'm trying to implement a webcam capture app which should take still frames, display them on the screen and save to the disk. Since I'm using SharpDX already to capture the screen, I thought it would be nice to use that library. I was not sure if SharpDX had any video capture capabilities, so I started searching and found parts of what it looks like a webcam capture prototype: var attributes = new MediaAttributes(1); attributes.Set<Guid>(CaptureDeviceAttributeKeys.SourceType,

jQuery webcam/flash: How to detect if webcam is active?

由 限于喜欢 提交于 2020-05-14 19:55:07
问题 I'm using this jQuery webcam plugin in a website I'm working on. If you go to the website, you'll notice it uses flash, and you have to click 'accept' in order to get it to work. I want to determine if the webcam is active (on) or not. How can I do this with javascript/jquery? In other words, what do I substitute in the if statement here? function capture_image(){ if(webcam.muted == true) {alert("hey");} I'm far from a pro in javascript and jquery, so real code would be much appreciated. Also

如何使用C#创建Windows Webcam应用

由 本秂侑毒 提交于 2020-04-12 16:31:28
最近想用C#写一个camera的应用。搜索了Google和StackOverflow，发现大部分的sample用了WIA或者DirectShow。WIA和DirectShow都没有直接提供C#接口，所以实现起来也比较复杂。试着运行了几个WIA的工程，在Windows10上还不起作用。发现微软提供了一个MediaCapture类，包含了丰富的C#接口，可用于音频，视频。要用这个类，就需要创建一个UWP工程。这里分享下如何使用MediaCapture的C#接口来获取camera的每一帧数据。 微软示例 微软在GitHub上放了大量的 UWP示例 ，里面包含了各种camera的接口使用方法。 在Android中要获取camera的每一帧数据，可以通过onPreviewCallback的回调函数实现。参考 CameraFrames 这个示例，也可以实现类似的功能。 如何创建Windows Webcam应用 1. 在 package.appxmanifest 中获取webcam权限： 2. 创建image element用于绘制webcam的预览界面： 3. 通过Image Element初始化 FrameRenderer ： _frameRenderer = new FrameRenderer(PreviewImage); 4. 初始化MediaCapture对象： // Create a

HTML Media Capture API vs. getUserMedia()

问题 currently, I'm trying to do some really simple thing (well, actually I thought it is simple...): I want to take a photo from the web-cam in a web-application . I stumbled over two possibilities: 1. The HTML Media Capture API which looks really easy: <input type="file" accept="image/*" capture="camera"> 2. JavaScript media streams, which also look pretty easy: navigator.getUserMedia() And here comes my question: The HTML Media Capture API is not working in desktop browsers and the JavaScript
