==Introduction==
The core of VLC media player is the [[LibVLC]], which provides an interface for applications to handle features such as playlist management, audio and video decoding and output, a thread system. All the [[LibVLC]] source files are located in the src/  directory and its subdirectories:

*config/: load the configuration from command line and configuration file, provides functions for the modules to read and write to configuration
*control/: functions to control the behaviour of [[LibVLC]], like Play/Pause, volume management, fullscreen, log verbosity, etc.
*extras/:
*modules/:
*network/:
*osd/:
*test/:
*text/:
*interface/: contains code for user interaction such as key presses and device ejection.
*playlist/: manages playlist interaction such as stop, play, next, or random playback.
*input/: opens an input module, reads packets, parses them and passes reconstituted elementary streams to the decoder(s).
*video_output/: initializes the video display, gets all pictures and subpictures (ie. subtitles) from the decoder(s), optionally converts them to another format (such as YUV to RGB), and displays them.
*audio_output/: initializes the audio mixer, ie. finds the right playing frequency, and then resamples audio frames received from the decoder(s).
*stream_output/: TODO
*misc/: miscellaneous utilities used in other parts of libvlc, such as the thread system, the message queue, CPU detection, the object lookup system, or platform-specific code.
