I’ve been playing with Audio Video Bridging (https://www.xmos.com/applications/avb) quite a bit lately and historically I’ve always used the AVDECC-Lib controller (https://github.com/audioscience/avdecc-lib) running on my laptop, either under Windows or Linux.
My intention is to create a completely standalone demo so I’ve since compiled the AVDECC-Lib controller for my Raspberry Pi.
The first thing to do is ensure that the GCC compiler is v4.7 :
sudo apt-get install g++-4.7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.7
sudo update-alternatives --config gcc
Next we need to ensure that we have all of the required applications and modules :
sudo apt-get install cmake
sudo apt-get install git
sudo apt-get install libpcap-dev
sudo apt-get install libreadline-dev
Now we clone AVDECC-Lib from github :
git clone git://github.com/audioscience/avdecc-lib --recursive
Finally we build the library and application :
cd avdecc-lib
cmake .
make
Now we can run the controller and manage our AVB network :
sudo controller/app/cmdline/avdecccmdline
Note, it is necessary to use sudo because the application requires direct access to the Ethernet PHY.
The controller will now give you a list of network interfaces and you need to choose the appropriate one (2).
AVDECC Controller version: v0.4.9
1 (lo, address: <127.0.0.1>)
2 (eth0, address: <192.168.128.180>)
Enter the interface number (1-2): 2
That’s it, we are now at the controller command line :
Enter "help" for a list of valid commands.
