ip-camera

问题 I have an IP-camera that serves images. These images are then processed via EmguCV and then I want to display the processed images. To show the images, I use this code: Window1(){ ... this.Dispatcher.Hooks.DispatcherInactive += new EventHandler(Hooks_DispatcherInactive); } Hooks_DispatcherInactive(...) { Next() } Next() the calls calls the image processing methods and (should) display the image: MatchResult? result = survey.Step(); if (result.HasValue) { Bitmap bit = result.Value.image.Bitmap

问题 I have an IP camera which is streaming video in MJPEG format. Now my aim is to receive it and display it in my own custom android app. For this I have three programming alternatives on android platform : Using inbuilt Anrdroid MediaPlayer class Using FFMPEG library in native C and accessing it through JNI Using GStreamer port on android to receive the stream So please suggest a better solution? I have no experience with FFMPEG or GStreamer. So what is the feasibility of doing this? 回答1: Use

问题 There is weird situation. I took standard google sample camera2API. I need that flash is worked permanently, regardless of outside light. In order to accomplish it i have changed one line of code: private void setAutoFlash(CaptureRequest.Builder requestBuilder) { if (mFlashSupported) { // requestBuilder.set(CaptureRequest.CONTROL_AE_MODE, CaptureRequest.CONTROL_AE_MODE_ON_AUTO_FLASH); requestBuilder.set(CaptureRequest.CONTROL_AE_MODE, CaptureRequest.CONTROL_AE_MODE_ON_ALWAYS_FLASH); } } It

问题 So far the solution I found requires a crossdomain.xml to work,but this is not available on an IP camera: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()"> <mx:Script> <![CDATA[ import utils.video.mjpeg.MJPEG; public function init():void{ Security.loadPolicyFile("xmlsocket:http://10.8.0.54/crossdomain.xml"); trace("xmlsocket:http://10.8.0.54/crossdomain.xml") var vid:MJPEG = new MJPEG("10.8.0.54", "

问题 I am trying to use a RTSP stream from an IP camera as video input source for various applications on Windows (eg. skype). The only solution I have found so far is using " webcam 7 ", an application that fetches RTSP stream and creates a virtual driver that registers in system as webcam and that any application can then use. Unfortunately, this application often becomes unstable and might crash randomly. Are there any alternative/better ways for achieving this? 回答1: Create your own DirectShow

问题 I'm trying to get live feed from TPLink TL-SC3171G IP cam in C# app. I've tried using AForge.NET library but no luck. The sample code from AForge.NET doesn't work for me. I'm getting "The remote server returned an error: (401) unauthorized access." I can access the cam via browser with basic ip adress: "http://192.168.168.20" . In app I've tried with: "http://username:password@192.168.168.20" "http://username:password@192.168.168.20:port" Can you please help me with some direction. It really

问题 A bit of context; this program was built originally to work with USB cameras - but because of the setup between where the cameras needs to be and where the computer is it makes more sense to switch to cameras run over a network. Now I'm trying to convert the program to accomplish this, but my efforts thus far have met with poor results. I've also asked this same question over on the OpenCV forums. Help me spy on my neighbors! (This is with their permission, of course!) :D I'm using: OpenCV v2

问题 I have to develop plug-in module which will allow us to stream live video from IP Cams if the IP of the cameras are available. The format and encoding for the same is: MPEG4 RTSP/RTP but I dont know from where to start. I have search in many site, unable to find any thing related. while browsing the Apples doc's, I found AVFoundation is used to stream live video from IP Cam's. UPDATE I found this from GITHUB but dont know How to implement it in my App. Please help me by sample code or related

问题 I'm looking for a way to interface with an external camera from an Android device. The reason it needs to be an external camera is because I need to be able to modify the camera (remove IR filter) and I have no desire to break an on-board phone camera. It doesn't matter how the camera connects whether it is through USB, bluetooth, WiFi, or some other communication protocol, the two devices just need to be able to talk without having a middleman server/router. I'm looking for a solution that:
