4 Author: Manuel Bachmann
9 Here are the plugins shipped in the source tree:
14 * Audio _(2 backends: ALSA/PulseAudio)_
15 * Radio _(1 backend: RTLSDR RTL2832U)_
16 * Media _(1 backend: Rygel UPnP)_
18 All plugins may not be built, depending on the development libraries present on the system at build time.
25 A sample Hello World plugin for demonstration and learning purposes.
27 This plugin provides a few unauthenticated requests, all beginning with "ping", to demonstrate basic binder capabilities.
31 * _ping:_ returns a success response
32 * _pingfail:_ returns a failure response
33 * _pingnull:_ returns a success response, with an empty JSON response field
34 * _pingbug:_ does a memory violation (intercepted by the binder)
35 * _pingJson:_ returns a success response, with a complex JSON response field
36 * _pingevent:_ broadcasts a global event
43 An sample Authentication plugin for demonstration purposes.
45 This plugin provides a few requests to demonstrate the binder's token-based security mechanism.
47 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.
51 * _ping:_ returns a success response
52 * _connect:_ creates a session and returns a new token
53 * _refresh:_ returns a new token
54 * _check:_ verifies the passed token is valid
55 * _logout:_ closes the session
62 A sample Tic Tac Toe game plugin.
64 This plugin provides an interactive Tic Tac Toe game where the binder returns the grid as a JSON response.
68 * _new:_ starts a new game
69 * _play:_ asks the server to play
70 * _move:_ gives a client move
71 * _board:_ gets the current board state, as a JSON structure
72 * _level_: sets the server level
73 * _join_: joins an existing board
74 * _undo_: undo the last move
75 * _wait_: wait for a move
82 A sample Audio plugin with 2 backends:
85 * PulseAudio (optional)
87 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.
91 * _ping:_ returns a success response
92 * _init:_ initializes backend, on the "default" sound card
93 * _volume:_ gets or sets volume, in % (0-100)
94 * _channels:_ gets or sets channels count (1-8)
95 * _mute:_ gets or sets the mute status (on-off)
96 * _play_: gets or sets the playing status (on-off)
98 _(if PulseAudio development libraries are not found at build time, only ALSA will be available)_
100 _(if a PulseAudio server is not found at runtime, the plugin will dynamically fall back to ALSA)_
102 _(a specifc backend can be forced by using this syntax before running afb-daemon : **$ export AFB_AUDIO_OUTPUT=Alsa**)_
109 A sample AM/FM Radio plugin with 1 backend:
111 * RTLSDR - Realtek RTL2832U dongles (mandatory)
113 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).
117 * _ping:_ returns a success response
118 * _init:_ initializes backend, looking for plugged-in devices
119 * _power:_ sets device power status (on-off)
120 * _mode:_ sets device reception mode (AM-FM)
121 * _freq:_ sets device frequency (in Hz)
122 * _mute_: sets device mute status (on-off)
123 * _play_: sets device playing status (on-off)
125 _(if rtlsdr development libraries are not found at build time, this plugin will not be built)_
132 A sample Media Server plugin with 1 backend:
136 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.
140 * _ping:_ returns a success response
141 * _init:_ initializes backend, looking for an active local UPnP server
142 * _list:_ returns list of audio files, as a JSON structure
143 * _select:_ select an audio files, by index number (001-...)
144 * _play:_ plays the currently selected audio file
145 * _stop:_ stops the currently selected audio file
146 * _pause:_ pauses the currently selected audio file
147 * _seek:_ seeks in the currently selected audio file, in seconds
148 * _upload:_ uploads an audio file, with a POST request
150 _(if GUPnP/GSSDP development libraries are not fund at build time, this plugin will not be built)_
