Hardware Accelerated Video Decode

Xe implements a high-performance and low-power HW acceleration for video decoding operations for multiple video codecs.

The HW decode is exposed by the graphics driver using the following APIs:

  • Direct3D* 9 Video API (DXVA2)
  • Direct3D11 Video API
  • Direct3D12 Video API
  • Intel Media SDK
  • MFT (Media Foundation Transform) filters.
  • Intel VA API

Xe supports full HW accelerated video decoding for AVC/HEVC/VP9/JPEG/AV1.

Note:

Video playback best performance can be achieved by enabling display MPO with minimized EU workloads. In some test scenarios, it may act differently.

For example, 8k playback on less than 8k monitors, in non-full screen mode or some UI operations and unexpected end user behaviors etc. - These will hit MPO limitation or simply applications do not use MPO.

Then graphics driver need to use EU for rendering/composition, and 8K E2E playback has dependency on EU counts capability.

Expected performance: More than 16 simultaneous decode streams @ 1080p.

Note:Actual performance depends on the processor SKU, content bit rate, and memory frequency. Hardware decode for H264 SVC is not supported.
