LibCecSharp

The managed binding for libCEC: control CEC-capable HDMI devices — power a TV on or to standby, become the active source, send remote keys, read device state — and receive bus events.

LibCecSharp (namespace CecSharp) is a pure C# assembly that binds the native library through its C API (P/Invoke over cecc.h), targeting net8.0. It runs anywhere the native library does: Windows, Linux, macOS and Raspberry Pi.

Requirements

  • A Pulse-Eight USB-CEC adapter, or a supported SoC-native CEC backend.
  • The native libCEC library on the loader path at runtime — cec.dll on Windows, libcec.so on Linux, libcec.dylib on macOS. This package is managed IL only; it does not carry the native library.

Install the native library with the Windows USB-CEC Adapter software, with apt-get install libcec8 on Debian/Ubuntu, or build it from source.

Usage

Derive from CecCallbackMethods to receive events, describe yourself in a LibCECConfiguration, then construct LibCecSharp.

using CecSharp;

class CecClient : CecCallbackMethods
{
    public override int ReceiveLogMessage(CecLogMessage message)
    {
        Console.WriteLine($"log: {message.Message}");
        return 1;
    }
}

var config = new LibCECConfiguration();
config.DeviceTypes.Types[0] = CecDeviceType.RecordingDevice;
config.DeviceName = "example";
config.ClientVersion = LibCECConfiguration.CurrentVersion;

using var lib = new LibCecSharp(new CecClient(), config);

// a null port opens the first adapter that opens, skipping any that another
// process is using
if (lib.Open(null, 10000))
{
    lib.PowerOnDevices(CecLogicalAddress.Tv);
    lib.Close();
}
