Note: Hardware encode for H264 SVC is not supported.
2.4.2.3 Hardware Accelerated Video Processing
There is hardware support for image processing functions such as De-interlacing, Film
cadence detection, Advanced Video Scaler (AVS), detail enhancement, image
stabilization, gamut compression, HD adaptive contrast enhancement, skin tone
enhancement, total color control, Chroma de-noise, SFC pipe (Scalar and Format
Conversion), memory compression, Localized Adaptive Contrast Enhancement (LACE),
spatial de-noise, Out-Of-Loop De-blocking (from AVC decoder), 16 bpc support for de-
noise/de-mosaic.
There is support for Hardware assisted Motion Estimation engine for AVC/MPEG2
encode, True Motion, and Image stabilization applications.
The HW video processing is exposed by the graphics driver using the following APIs:
• Direct3D* 9 Video API (DXVA2)
• Direct3D 11 Video API
• Intel Media SDK
• MFT (Media Foundation Transform) filters
• Intel CUI SDK
Note: Not all features are supported by all the above APIs. Refer to the relevant
documentation for more details.
2.4.2.4 Hardware Accelerated Transcoding
Transcoding is a combination of decode video processing (optional) and encode. Using
the above hardware capabilities can accomplish a high-performance transcode pipeline.
There is not a dedicated API for transcoding.
The processor graphics supports the following transcoding features:
• Low-power and low-latency AVC encoder for video conferencing and Wireless
Display applications.
• Lossless memory compression for media engine to reduce media power.
• HW assisted Advanced Video Scaler.
• Low power Scaler and Format Converter.
