Hardware Acceleration with AMD GPUs

AMD Advanced Media Framework (AMF) is AMD's multimedia framework for real-time video processing. It abstracts the platform and API details underneath it, and gives Emby access to the video engines built into Radeon GPUs and APUs.

GPU Context Types

An AMD GPU can present several context types at once, and Emby prefers AMF where it is available.

AmdWindows is AMF on Windows.

AmdLinux is AMF on Linux.

VulkanAmd is the generic, cross-vendor Vulkan interface on the same card - a separate context available alongside AMF, not a replacement for it.

Vaapi is the generic, vendor-agnostic VAAPI context. It appears when the card's VAAPI encoder did not identify itself as AMF specifically, which is why it can show up alongside the AMF contexts rather than instead of them.

Which of these exist on your machine, and which one is in use, is shown per device in Advanced Mode.

Hardware Requirements

AMF works with most recent Radeon GPUs from the Southern Islands family onwards, and with APUs of the Kabini, Kaveri and Carrizo families and newer.

Drivers

On Linux nothing needs installing - the necessary drivers ship with Emby Server. On Windows, install the Radeon software. See GPU Setup.

What Your Card Can Do

Emby detects the encoders, decoders and filters each device actually offers, rather than assuming them from the model name, and shows them per device in the transcoding configuration. What a given GPU supports depends on its generation, its driver and the operating system, so the configuration is the authoritative answer for your own hardware.
