HID API for Elgato UVC devices

The folder Library contains cross-platform code to access device-specific features of selected Elgato video products.

The CMake project in this folder builds a small console app for testing. Modify selectedDeviceID in SampleCode/main.cpp to select the correct device type.

Supported platforms

• Windows (10 or higher)
• macOS

Supported devices

• HD60 S+
• HD60 X

Supported features

• Switch on-device HDR tonemapping on/off
• Read HDMI HDR status packet (for HDR detection)

Limitations

The library was written for macOS and Windows. However, the sample project was only built with Visual Studio 2019 and tested on Windows so far.

Driver API for Elgato devices

For non-UVC devices device properties can be accessed via a custom driver property set (IKsPropertySet).

Sample code is provided, see SampleCode/DriverInterface.h/.cpp

Supported platforms

• Windows (10 or higher)

Supported devices

• 4K60 Pro MK.2
• 4K60 S+

Supported features

• Switch on-device HDR tonemapping on/off (4K60 Pro MK.2 only)
• Set video compression (4K60 S+ only)
• Read HDMI HDR status packet (for HDR detection)

4K60 Pro MK.2

To receive HDR the format on DirectShow filter pin must be set to P010.

4K60 S+

The 4K60 S+ always produces compressed video output. For HDR the encoder format must be set to HEVC via the driver interface.
