Usage - sample application

You can easily start the compilation and the usage just by running the CMakeList file with a proper version of CMake and then follow the usual steps. The sample application lets you record the screen with the audio or a portion of it, just follow the instructions.

Usage - library

The library start with the Controller object which needs at the creation step the audio device chosen (just look the previous instructions) and the videoUrl which is different from each operating system (on Linux system, the library can give you the name of the display just by calling the DisplayInfo.showInfos() method). Moreover, a SRSettings parameter is requested, which is a simple structure which needs to be filled with all the information about the recording. After all of this you can easily start the capture with startCapture() methods and the recording process should be fine from that moment, just be aware of the possible exception that could be thrown by the method. From that moment you can pauseCapture(), resumeCapture() and stopCapture(). You can retrieve the file from the folder where your executable was running.
