About

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)

Supported platforms

Linux & BSD

Prerequisites

libCEC needs the following dependencies in order to work correctly:

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

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

Compilation

To compile, execute the following commands:

mkdir build
cd build
cmake ..
make
sudo make install

Raspberry Pi

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 \
      ..

Exynos

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

cmake -DHAVE_EXYNOS_API=1 ..

TDA995x

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

cmake -DHAVE_TDA995X_API=1 ..

Debian

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

Apple OS X

Prerequisites

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

Compilation

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

Microsoft Windows

Prerequisites

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

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

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

Compilation

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

Developers

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

C++ developers

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

C developers

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

.NET developers

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

Python developers

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