Detail of plugins

### Hello World

A sample Hello World plugin for demonstration and learning purposes.

This plugin provides a few unauthenticated requests, all beginning with "ping" ("pingSample", "pingJson", "pingFail"...) to demonstrate basic binder capabilities.

### Authentication

An sample Authentication plugin for demonstration purposes.

This plugin provides a few requests to demonstrate the binder's token-based security mechanism.

Calling "connect" with a security token will initiate a session, calling "refresh" will issue a new token and invalidate the previous one, calling "logout" will invalidate all tokens and close the session.

### Tic Tac Toe

A sample Tic Tac Toe game plugin.

This plugin provides an interactive Tic Tac Toe game where the binder returns the grid as a JSON response.

### Audio

A sample Audio plugin with 2 backends: * ALSA (mandatory) * PulseAudio (optional)

This plugin is able to initialize a specific soundcard, define volume levels, channels (mono/stereo...), mute sound, and play a 22,050 Hz PCM stream.

(if PulseAudio development libraries are not found at build time, only ALSA will be available)

(if a PulseAudio server is not found at runtime, the plugin will dynamically fall back to ALSA)

(a specifc backend can be forced by using this syntax before running afb-daemon : $ export AFBAUDIOOUTPUT=Alsa)

### Radio

A sample AM/FM Radio plugin with 1 backend: * RTLSDR - Realtek RTL2832U dongles (mandatory)

This plugin is able to initialize specific RTL2832U dongles, switch between AM/FM modes, define frequency, mute sound, and play sound (if combining with the audio plugin).

(if rtlsdr development libraries are not found at build time, this plugin will not be built)

### Media

A sample Media Server plugin with 1 backend: * Rygel

(if GUPnP/GSSDP development libraries are not found at build time, this plugin will not be built)

This plugin is able to detect a local Rygel UPnP media server, list audio files, select an audio file for playback, play/pause/seek in this file, upload an audio file to the server.

Sample command-line applications: afb-client-demo (built by default)

Sample HTML5 applications: test/*.html, afb-client, afb-radio

Sample Qt/QML applications: test/token-websock.qml
