+ Generic Webcam Java Utility
++The goal of this project is to provide really simple webcam API allowing you to use your +build-in, external (USB-connected) webcams or IP / network cameras directly from Java code. +It provides basic webcam +interface and a set of additional drivers which can be used to replace default build-in +drivers to extend and/or replace default functionality. +
+ +Continous Integration build status (Travis CI):
+ +
+
+
+
+
+Webcam Capture is avilable in Maven Central, so if you can add its dependency to your +project if you are using one of the dependency manager: +
+ ++<dependency> + <groupId>com.github.sarxos</groupId> + <artifactId>webcam-capture</artifactId> + <version>0.3.5</version> +</dependency> ++ +
+Download ZIP file containing complete API reference, required JARs, sources and examples +(link is visible at the right top corner of this page), uncompress, and add webcam-capture-[version].jar +and all JARs under libs directory to your project's classpath: +
+ ++Currently Webcam Capture supports the following drivers: +
+ ++This is IP camera driver for Webcam Capture project. It allows Webcam Capture to +handle pictures from IP cameras supporting JPEG and MJPEG (Motion JPEG) compression. +For more information about supported models, how to extend, examples, use-cases, please +follow to the Github project available here. +
+ ++This driver is available in Maven Central. +
+ ++This is driver containing video grabber for Webcam Capture project. It utilizes JMF +capabilities to access PC webcam (those USB-connected too) and can be used as a replacement +for default build-in driver. Its advantage is the fact it's pretty fast, but unformtunately, +from the other hand, it requires JMF +to be installed on your PC. +
+ ++If you do not want to use JMF (due to e.g. licensing issues), you can choose +FMJ, which is a freeware replacement for JMF. +
+ ++NOTE! Be aware of the fact that both JMF and FMJ are not being maintained any more! +
+ ++This driver is available in Maven Central. +
+ ++This is driver containing video grabber for Webcam Capture project. It utilizes +OpenIMAJ framework +capabilities to access PC webcam and can be used as a replacement +for default build-in driver. Its advantage is the fact it's pretty fast, supports +multiple platforms, but disadventage is the size of required 3rd party +JARs (around ~20MB). Default build-in driver uses OpenIMAJ natives to support video grabbing, +but id does not require all those additional JARs. +
+ ++This driver is NOT available in Maven Central, but it can be used in Maven build. +In such a case user has to add those repositories to project's POM: +
+ ++<repositories> + <repository> + <id>OpenIMAJ maven repository</id> + <url>http://maven.openimaj.org/</url> + </repository> + <repository> + <id>Octopussy thirdparty maven repository</id> + <url>http://octopussy.ecs.soton.ac.uk/m2/thirdparty/</url> + </repository> + <repository> + <id>OpenIMAJ Snapshots maven repository</id> + <url>http://octopussy.ecs.soton.ac.uk/m2/snapshots/</url> + </repository> +</repositories> ++ + +
+This is driver containing video grabber for Webcam Capture project. It utilizes +LTI-CIVIL project +capabilities to access PC webcam and can be used as a replacement +for default build-in driver. LTI-CIVIL supports Windows, Linux and MAC OS platforms. +For Mac OS it utilizes QTJ framework capabilities. For other ones it uses precompiled +natives. +
+ ++This driver is NOT available in Maven Central, but it can be used in Maven build. +In such a case user has to add those repositories to project's POM: +
+ ++<repositories> + <repository> + <id>sarxos-repo</id> + <url>http://repo.sarxos.pl/maven2</url> + </repository> +</repositories> ++ +
+NOTE! Be aware of the fact that LTI-CIVIL not being maintained any more by its owner! +
+ + +EXPERIMENTAL STUFF!
+ ++This is driver containing video grabber for Webcam Capture project. It utilizes +JavaCV Java wrapper for +OpenCV project +capabilities to access PC webcam and can be used as a replacement +for default build-in driver. Its advantage is quite stable interface, but unfortunately +it requires quite huge (around ~100MB) pre-installed OpenCV bundle. +
+ ++This driver is NOT available in Maven Central, but it can be used in Maven build. +In such a case user has to add those repositories to project's POM: +
+ ++<repositories> + <repository> + <id>javacv</id> + <url>http://maven2.javacv.googlecode.com/git</url> + </repository> + <repository> + <id>kevoree</id> + <url>http://maven.kevoree.org/release</url> + </repository> +</repositories> ++ +
EXPERIMENTAL STUFF!
+ ++This is driver containing video grabber for Webcam Capture project. It utilizes +VLCj Java wrapper for Videolan +VLC project +capabilities to access PC webcam and can be used as a replacement +for default build-in driver. Unfortunately it require VLC media player to be +pre-installed on the system where driver will be used. +
+ ++This driver is NOT available in Maven Central, but it can be used in Maven build. +In such a case user has to add those repositories to project's POM: +
+ ++<repositories> + <repository> + <id>caprica</id> + <url>http://www.capricasoftware.co.uk/repo</url> + </repository> +</repositories> ++ + + + + + + +
To capture single image and save it to disk:
+ +
+Webcam webcam = Webcam.getDefault();
+BufferedImage image = webcam.getImage();
+ImageIO.write(image, "PNG", new File("test.png"));
+
+
+If you have more then one webcam connected to your computer:
+ ++Webcam laptop = Webcam.getWebcams().get(0); +Webcam kitchen = Webcam.getWebcams().get(1); +Webcam roof = Webcam.getWebcams().get(2); ++ +
To detect motion with your webcam - loop solution:
+ +
+WebcamMotionDetector detector = new WebcamMotionDetector(Webcam.getDefault());
+detector.setInterval(100); // one check per 100 ms (10 FPS)
+detector.start();
+
+while (true) {
+ if (detector.isMotion()) {
+ System.out.println("Detected motion I, alarm turn on you have");
+ }
+ Thread.sleep(500);
+}
+
+
+To detect motion with webcam - listener solution:
+ +
+public class DetectMotionExample implements WebcamMotionListener {
+
+ WebcamMotionDetector detector = new WebcamMotionDetector(Webcam.getDefault());
+
+ public DetectMotionExample() {
+ detector.setInterval(100); // one check per 100 ms (10 FPS)
+ detector.addMotionListener(this);
+ detector.start();
+ }
+
+ @Override
+ public void motionDetected(WebcamMotionEvent wme) {
+ System.out.println("Detected motion I, alarm turn on you have");
+ }
+
+ public static void main(String[] args) throws IOException {
+ new DetectMotionExample();
+ System.in.read(); // keeps your program open
+ }
+}
+
+
++You can display image from webcam in Swing JPanel. There is a special component +designed for this. +
+ +
+JFrame window = new JFrame("Test Webcam Panel");
+window.add(new WebcamPanel(Webcam.getDefault()));
+window.pack();
+window.setVisible(true);
+window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
+
+
++To use Webcam Capture together with IP or network camera you have to add +IP / network camera driver +to your Webcam Capture project. +
+ +
+IpCamDevice ipcam = new B7210("B7210", "114.32.216.24");
+ipcam.setAuth(new IpCamAuth("demo", "demo"));
+ipcam.setSize(B7210.SIZE_QVGA);
+
+IpCamDriver driver = new IpCamDriver();
+driver.register(ipcam);
+
+Webcam.setDriver(driver);
+
+WebcamPanel panel = new WebcamPanel(Webcam.getDefault());
+panel.setFPS(0.5); // 1 frame per 2 seconds
+
+JFrame f = new JFrame("Night Tree Somewhere");
+f.add(panel);
+f.pack();
+f.setVisible(true);
+f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
+
+
+More IP / network camera examples are available in Github project's page.
+
+
+Logging (Logback via SLF4J) is already there, so you can enable it simply by adding +logback.xml configuration file somewhere in your filesystem and calling: +
+ +
+WebcamLogConfigurator.configure("path/to/logback.xml");
+
+
+
++There are more examples available in src/example, don't forget to +check them - please follow to the Github Project's Page where Webcam Capture +source code is stored! +
