=========================================
AM Monitor (GENIVI Audio Manager Monitor)
=========================================
Authors: JoonCheol Park <jooncheol.park@windriver.com>
Daewon Park <daewon.park@windriver.com>
Introduction
------------
The AM Monitor shows to working flow of the AM. In this demo, we use the AM with 2 Plugins for PulseAudio and Audio Policy Control. When we play the audio in this app, we can see the internal status of connections in AM and status of the PulseAudio.
Dependencies
------------
- Audio Manager (branch Intreprid_stable_branch, Version 6.1)
+ 2 patches for PulseAudio Routing Plugin and Audio Policy Control Plugin
(http://git.projects.genivi.org/?p=meta-genivi-demo.git;a=tree;f=recipes-multimedia/audiomanager/audiomanager;h=f134ecaf6190ec272bd6136ee88f0e86a8b86047;hb=HEAD)
- PulseAudio
- DBus
- Qt5
Build Instruction for Ubuntu 14.04 PC
-------------------------------------
- Build Audio Manager + 2 patches
$ git clone git://git.projects.genivi.org/AudioManager.git
$ curl "http://git.projects.genivi.org/?p=meta-genivi-demo.git;a=blob_plain;f=recipes-multimedia/audiomanager/audiomanager/0001-Porting-Pulse-Routing-Interface-from-AM-v1.x-to-AM-v.patch;h=7d6ebbf710d0a0d46d99797f5ef6dd3712a888fe;hb=HEAD" > 0001-Porting-Pulse-Routing-Interface-from-AM-v1.x-to-AM-v.patch
$ curl "http://git.projects.genivi.org/?p=meta-genivi-demo.git;a=blob_plain;f=recipes-multimedia/audiomanager/audiomanager/0001-Porting-Pulse-Control-Interface-from-AM-v1.x-to-AM-v.patch;hb=HEAD" > 0001-Porting-Pulse-Control-Interface-from-AM-v1.x-to-AM-v.patch
$ cd AudioManager
$ git checkout Intreprid_stable_branch
$ patch -p1 < ../0001-Porting-Pulse-Routing-Interface-from-AM-v1.x-to-AM-v.patch
$ patch -p1 < ../0001-Porting-Pulse-Control-Interface-from-AM-v1.x-to-AM-v.patch
$ mkdir build
$ cd build
$ cmake -DWITH_PULSE_ROUTING_PLUGIN=ON -DWITH_PULSE_CONTROL_PLUGIN=ON -DWITH_ENABLED_IPC=DBUS -DWITH_DATABASE_STORAGE=OFF -DWITH_DLT=OFF -DCMAKE_INSTALL_PREFIX=(PREFIX on your dev environment) ..
$ make
$ make install
- Build AM Monitor
$ git clone git://git.projects.genivi.org/AudioManagerDemo.git
$ qmake
or
$ qmake INCLUDEPATH=(PREFIX-OF-AM)/include
$ make
Running AM Monitor on Ubuntu 14.04 PC
-------------------------------------
1. Set testing environment
$ . pc-env
This script creates 2 virtual sink device for PulseAudio Daemon. You can check with "pacmd list-sinks". If you want to remove created sink device, execute 'deactivate' on the shell
2. Execute AM
$ AudioManager -V -c(PREFIX-OF-AM)/lib/audioManager/control/libPluginControlInterface.so -l(PREFIX-OF-AM)/lib/audioManager/command/ -r(PREFIX-OF-AM)/lib/audioManager/routing/
3. Execute AM Monitor
$ ./AudioManagerMonitor --debug
If you don't use any argument, AM Monitor will be running as fullscreen mode. Please refer the usage with "--help" option.
Audio Policy Rule Configuration example
----------------------------------------
- Preset of AM Sources and Sinks
(PREFIX-OF-AM)/lib/audiomanager/routing/libPluginRoutingInterfacePULSE.conf
It defines 5 preset of AM Sources - Entertainment, Navigation, TTS ...
- Policy Rule
(PREFIX-OF-AM)/lib/audiomanager/control/libPluginControlInterface.conf
It defines audio policy scenario. E.g - When play the NAVI sound alert during Media playing, Sink Volume of previous Media goes down to 50%.
To do items
------------
- AM Monitor
- Use CommonAPI for command interface in AM Monitor App
- AM Plugins
- Enhance the Routing Plugin for PulseAudio
- Implement missing code for all Routing Plugin APIs
- Enhance the configuration syntax
- Enhance the Conrol Plugin for Audio Policy
- More flexible and programmable audio policy configuration using JavaScript
