This library provides support for Pulse-Eight's USB-CEC adapter and other CEC capable hardware, like the Raspberry Pi.

You can find a list of frequently asked questions on [libCEC's FAQ page] (http://libcec.pulse-eight.com/faq)

libCEC needs the following dependencies in order to work correctly:

• [p8-platform] (https://github.com/Pulse-Eight/platform) 2.0 or later
• udev v151 or later
• cdc-acm support compiled into the kernel or available as module
• [liblockdev] (https://packages.debian.org/search?keywords=liblockdev) 1.0 or later

To compile libCEC on Linux, you'll need the following dependencies:

• [cmake 2.6 or better] (http://www.cmake.org/)
• a supported C++ 11 compiler
• [liblockdev] (https://packages.debian.org/search?keywords=liblockdev) 1.0 development headers

The following dependencies are recommended. Without them, the adapter can not be (fully) auto-detected.

• pkg-config
• udev development headers v151 or later
• X randr development headers

To compile libCEC on a new Debian/Ubuntu installation, follow these instructions:

apt-get update
apt-get install cmake liblockdev1-dev libudev-dev libxrandr-dev python-dev swig
cd
git clone https://github.com/Pulse-Eight/platform.git
mkdir platform/build
cd platform/build
cmake ..
make
sudo make install
cd
git clone https://github.com/Pulse-Eight/libcec.git
mkdir libcec/build
cd libcec/build
cmake ..
make -j4
sudo make install
sudo ldconfig

If you're compiling for a Raspberry Pi, then the path to the required headers and libraries can be set manually, in case it's not in a standard system directory:

cmake -DRPI_INCLUDE_DIR=/path/to/vc/include \
      -DRPI_LIB_DIR=/path/to/vc/lib \
      ..

If you're cross compiling, then you can set the correct toolchain like this (for the Raspberry Pi):

cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/CrossCompile.cmake \
      -DXCOMPILE_BASE_PATH=/path/to/tools/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi \
      -DXCOMPILE_LIB_PATH=/path/to/firmware/hardfp/opt/vc/lib \
      -DRPI_INCLUDE_DIR=/path/to/firmware/hardfp/opt/vc/include \
      -DRPI_LIB_DIR=/path/to/firmware/hardfp/opt/vc/lib \
      ..

To compile libCEC on a new Raspbian installation, follow these instructions:

sudo apt-get update
sudo apt-get install cmake liblockdev1-dev libudev-dev libxrandr-dev python-dev swig
cd
git clone https://github.com/Pulse-Eight/platform.git
mkdir platform/build
cd platform/build
cmake ..
make
sudo make install
cd
git clone https://github.com/Pulse-Eight/libcec.git
mkdir libcec/build
cd libcec/build
cmake -DRPI_INCLUDE_DIR=/opt/vc/include -DRPI_LIB_DIR=/opt/vc/lib ..
make -j4
sudo make install
sudo ldconfig

To compile in support for Exynos devices, you have to pass the argument -DHAVE_EXYNOS_API=1 to cmake:

cmake -DHAVE_EXYNOS_API=1 ..

To compile in support for TDA995x devices, you have to pass the argument -DHAVE_TDA995X_API=1 to cmake:

cmake -DHAVE_TDA995X_API=1 ..

Use the following commands to create a debian package:

source /etc/lsb-release
sed "s/#DIST#/${DISTRIB_CODENAME}/g" debian/changelog.in > debian/changelog
dpkg-buildpackage

To compile libCEC on OS X, you'll need the following dependencies:

• [p8-platform] (https://github.com/Pulse-Eight/platform) 2.0 or later
• [cmake 2.6 or better] (http://www.cmake.org/)
• a supported C++ 11 compiler
• xcode 3.2.6 or later

To compile, execute the following command:

mkdir build
cd build
cmake ..
make
sudo make install

Note: You may need to copy pkg.m4 to your m4 sources directory

To compile libCEC on Windows, you'll need the following dependencies:

• [p8-platform] (https://github.com/Pulse-Eight/platform) 2.0 or later
• [cmake 2.6 or better] (http://www.cmake.org/)
• [Visual Studio 2013] (https://www.visualstudio.com/)
• [Windows DDK (Driver Development Kit)] (https://msdn.microsoft.com/en-us/windows/hardware/hh852365.aspx)
• To create an installer, you'll need [Nullsoft's NSIS] (http://nsis.sourceforge.net/)

When compiling LibCecSharp, you'll need the following versions too:

• Visual Studio 2012
• Visual Studio 2010
• Visual Studio 2008

To compile libCEC, follow these instructions:

• run support\build.cmd to build libCEC and cec-client
• open project\libcec.sln with Visual Studio 2013.
• build the project.

To develop for libCEC or cec-client in Visual Studio:

• run support\visual-studio.cmd

To build an installer on Windows:

• go to project and execute create-installer.bat to create the installer.
• the installer is stored as build\libCEC-installer.exe

We provide a C, C++, Python and .NET CLR interface to the adapter.

• the API can be found in include/cec.h
• an example implementation can be found in src/cec-client/cec-client.cpp

• the API can be found in include/cecc.h
• an example implementation can be found in src/cecc-client/cecc-client.cpp

• add a reference to LibCecSharp.dll
• an example can be found in src\CecSharpTester\CecSharpClient.cs

• the API is exported to Python through Swig
• an example can be found in src/pyCecClient
