Video Acceleration (VA) API

Introduction

The main motivation for VA-API (Video Acceleration API) is to enable hardware accelerated video decode and encode at various entry-points (VLD, IDCT, Motion Compensation etc.) for the prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, VC-1/VMW3, and JPEG, HEVC/H265, VP8, VP9) and video pre/post processing

VA-API is split into several modules:

• Core API
• Encoder (H264, HEVC, JPEG, MPEG2, VP8, VP9)
  • H.264 encoding API
  • HEVC encoding API
  • JPEG encoding API
  • MPEG-2 encoding API
  • VP8 encoding API
  • VP9 encoding API
• Decoder (HEVC, JPEG, VP8, VP9, AV1)
  • HEVC decoding API
  • JPEG decoding API
  • VP8 decoding API
  • VP9 decoding API
  • api_dec_av1
• Video processing API
• FEI (H264, HEVC)
  • FEI encoding common API
  • H.264 FEI encoding API
  • HEVC FEI encoding API
