webcam

问题 Even though it seems to be in some kind of jeopardy, the open video standard is a great idea. I saw some demos on motion tracking with it - just proofs-of-concept, but interesting nonetheless. Now, I'd say that concepts like these would really be a gain, if there would be access to the user's webcam... Just imagine browsing through Flickr with your hands in mid-air. I have Googled a little, but I can't find any detailed discussion on the subject. It is mentioned in some places, but that doesn

问题 I'm using OpenCV 2.2 with visual studio 2010 on a win 7 64 bit pc. I'm able to display pictures and play AVI files through OpenCV as given in the book "Learning OpenCV" but I'm not able to capture webcam images. Even the samples given along with the OpenCV files cant access the webcam. I get asked for " video source -> capture source" and there are two options: HP webcam Splitter and HP webcam. If I select HP webcam the window closes immediately without displaying any error. (i think any

问题 I'm trying to take pictures with a webcam in my c# application. I found out to use DirectShowLib. After a hard research, I found an example of how using the webcam, it displays the video on screen perfect, but it can't take the bitmap image for saving it at my will. sample of the code I found to take the picure would be public Bitmap snapImage() { IVMRWindowlessControl9 windowlessCtrl = null; IBaseFilter vmr9 = null; vmr9 = (IBaseFilter)new DirectShowLib.VideoMixingRenderer9(); DirectShowLib

问题 I don't have my own Flash Media Server. I can however use the Highwinds CDN. They run FMS on their CDN. When you schedule a live event, Highwinds gives you two urls: the "server" and "stream name". Examples: server: rtmp://fli003.am4.hwcdn.net/XXXX/ definst stream name: fli/00000-streamname?encoderuser=XXX&encoderpassword=YYY These two urls can be pasted into the Flash Media Live Encoder application to stream the live event. The respective field names in Flash Media Live Encoder are "FMS URL"

问题 I am trying to overlay an image over the webcam feed. Here's the main section of the code - # Load our overlay image: glasses.png imgGlasses = cv2.imread('1.png') # Create the mask for the glasses imgGlassesGray = cv2.cvtColor(imgGlasses, cv2.COLOR_BGR2GRAY) ret, orig_mask = cv2.threshold(imgGlasses, 10, 255, cv2.THRESH_BINARY) # Create the inverted mask for the glasses orig_mask_inv = cv2.bitwise_not(orig_mask) # Convert glasses image to BGR # and save the original image size (used later

问题 Is it possible for AS3 to record a video with a webcam and save it to a local disk/to a network server? 回答1: You can use an Air app called AirCam to achieve this. It uses the BitmapData class to generate a FLV file. If you want to build it yourself they also include the the source code on the site. There class does not support sound though. The purpose of this revolutionary new class is to record a stream of BitmapData to a FLV-file, because writing directly, and especially the converting

问题 In a nutshell, I need a way to stream (or otherwise play) a movie along with 3 to 4 other 'show angles', with the user being able to change the stream they're viewing. End result should be a video player with links/buttons for the other angles, allowing the user to switch camera streams (angles) as they wish. Here's an example: You load a page with a DIY video.. and since it includes a fairly detailed assembly process, there are 4 cameras recording different angles or locations of the work

问题 To capture video from a web-camera, I used the example code from the DisplayWebcamVideo.java It was amended resolution: params.setValue ("video_size", "640x480"); To save images added to the line: private static void updateJavaWindow (BufferedImage javaImage) { mScreen.setImage (javaImage); ImageIO.write (javaImage, "jpg", new File (fileOut)); } All the remains, but while maintaining the periodic part of the image is painted gray. Besides, if I understood correctly, before saving the next

问题 I am currently trying to time alerts to appear 3 seconds after the viewer grants permission of webcam. The alerts are supposed to also have audio with them, as they're supposed to be triggered at the same time. The webcam has a face tracking feature with it, so there is a lot of extra code. So I don't know javascript, so please visuals help a lot more than statements. This is my current code I am working with. <!doctype html> <html> <head> <meta charset="utf-8"> <title>eve_</title> <link rel=
