Cordova Plugin (iOS + Android) serving Live Images from the Camera over HTTP

Primary LanguageObjective-C

#CameraServer Plugin For Cordova

Supported platform:

  • iOS
  • Android

Provides Live Camera images over HTTP (over Wifi or locally to a Cordova Application):

Why over HTTP ?

  • A known memory leak problem occurs when retrieving data/result in Cordova (see CameraPlus)
  • It's faster and purely in native code so it was suitable for our application Netcam Studio Smart Camera

#How to use CameraServer?

Add the plugin to your cordova project:

cordova plugin add https://github.com/Moonware/cordova-cameraserver

Removing the plugin to your cordova project:

cordova plugin rm cordova-plugin-cameraserver

Dependency

Since Cordova 4.0, it may be required to install the cordova-plugin-whitelist to allow calls to 127.0.0.1 and localhost

Without this step, your application may not be allowed to pull and display images from the camera server plugin.

Please follow installation and setup instructions here: cordova-plugin-whitelist

#Javascript APIs

startServer( options, success_callback, error_callback );

stopServer( success_callback, error_callback );

getURL( success_callback, error_callback );

getLocalPath( success_callback, error_callback );

getNumRequests( success_callback, error_callback );

startCamera( success_callback, error_callback );

stopCamera( success_callback, error_callback );

/* Just for testing, do not use this since it leaks */
getJpegImage( success_callback, error_callback );

#Quick Start

Start the Web Server

cordova.plugins.CameraServer.startServer({
    'www_root' : '/',
    'port' : 8080,
    'localhost_only' : false,
    'json_info': []
}, function( url ){
    // if server is up, it will return the url of http://<server ip>:port/
    // the ip is the active network connection
    // if no wifi or no cell, "127.0.0.1" will be returned.
    console.log('CameraServer Started @ ' + url); 
}, function( error ){
    console.log('CameraServer Start failed: ' + error);
});

Start the Camera Capture (will act on demand when a HTTP request arrives)

cordova.plugins.CameraServer.startCamera(function(){
      console.log('Capture Started');
  },function( error ){
      console.log('CameraServer StartCapture failed: ' + error);
  });

Downloading a Live Image in Javascript (AngluarJS / Ionic)

var localImg = 'http://localhost:8080/live.jpg';

$http.get(localImg).
    success(function(data, status, headers, config) {
        console.log("Image Downloaded");
    }).
    error(function(data, status, headers, config) {
        console.log("Image Download failed");
    });

Displaying a Live Image in a Cordova App is as simple as:

<img src='http://localhost:8080/live.jpg'>
