+ + ++In the development phase you will probably kill running application many +time (by stop button in Eclipse, Netbeans or other IDE), or by calling +kill -TERM <pid> command from CLI. You have to be aware that +killing running application when Webcam Capture is already running can have +unwanted side-effects, such as: +
+ ++All those issues arose from the same root cause - memory has not been +properly deallocated in the native layer. That's because you killed application +instead of closing it gracefully. +
+ ++However, there is a solution for this problem. For such purpose special TERM +signal handler has been implemented, and you can enable it before you actually +start using Webcam Capture API. This can be done by calling this code (please +make sure to call it before you use any other method!): +
+ ++Webcam.setTermSignalHandler(true); ++ +
+IMPORTANT NOTE! This is development setting and shall not be used +in production code!!! It modified the way of how JVM terminates its process, so +depending on the system there can be some unknown side-effects. Also features used +in this handler are undocumented and can be removed in further Java releases +without prior notification. +
+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: +
+Logging has been implemented via SLF4J API, so all you need to do +is to add specific implementation and create configuration file. +
+ ++This paragraph describes in short how to use Logback +to enable logs from Webcam Capture API. +
+ ++Go to Logback home page and download +ZIP files containing all required JARs. Extract ZIP and add those files into +your classpath: +
+ ++NOTE! The [version] is current Logback release signature (e.g. 1.0.9). +
+ ++Create logback.xml file and put this content inside: +
