The AMD MEP Enumerator is a Windows driver associated with AMD's multimedia or video processing hardware, typically found on systems with AMD graphics or APUs (Accelerated Processing Units). "MEP" likely stands for Media Engine Processor, which is a part of AMD's technology for video playback, encoding, and decoding, possibly related to HDMI audio, video decoding, or other multimedia functions on AMD platforms.

The AMD MEP Enumerator driver enables Windows to properly recognize and interact with the multimedia or video hardware, ensuring that tasks like video decoding, media playback, or multimedia interfaces (such as HDMI or DisplayPort outputs) work correctly. It is often a part of the AMD Catalyst or AMD Radeon Software drivers that manage AMD's graphics and video capabilities.
