List of bindings

Here are the bindings shipped in the source tree:

All bindings may not be built, depending on the development libraries present on the system at build time.

Detail of bindings

Hello World

A sample Hello World binding for demonstration and learning purposes.

This binding provides a few unauthenticated requests, all beginning with "ping", to demonstrate basic binder capabilities.

Verbs:


Authentication

An sample Authentication binding for demonstration purposes.

This binding 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.

Verbs:


Tic Tac Toe

A sample Tic Tac Toe game binding.

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

Verbs:


Audio

A sample Audio binding with 2 backends:

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

Verbs:

(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 binding will dynamically fall back to ALSA)

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


Radio

A sample AM/FM Radio binding with 1 backend:

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

Verbs:

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


Media

A sample Media Server binding with 1 backend:

This binding 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.

Verbs:

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