VAAPI

VAAPI (Video Acceleration API) is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities for video processing. It consists of a main library and driver-specific acceleration backends for each supported hardware vendor.

The following features are currently supported in VAAPI for Intel graphics cards:

Hardware Supported

  • Intel® GMA X4500HD.
  • Intel® HD Graphics (in Intel® 2010 Core™ i7/i5/i3 processor family).
  • Intel® HD Graphics 2000/3000 (in 2nd Generation Intel® Core™ i7/i5/i3 Processor family).
  • Intel® HD Graphics 2500/4000 (in 3nd Generation Intel® Core™ i7/i5/i3 Processor family).
  • Intel® HD Graphics 4200/4400/4600/5000, Intel® Iris™ Graphics 5100, and Intel® Iris™ Pro Graphics 5200 (in 4nd Generation Intel® Core™ i7/i5/i3 Processor family).

Features

  • Support MPEG2 decode acceleration Main Profile @ HL up to 80 Mbps.
  • Support MPEG2 encode acceleration Main profile @ HL up to 80 Mbps (excludes GMA X4500HD, HD Graphics and HD Graphics 2000/3000)
  • Support VC-1 decode acceleration Advanced Profile @ Level 3 up to 40 Mbps (excludes GMA X4500HD and HD Graphics)
  • Support H.264/AVC decode acceleration High Profile @ L4.1 up to 40 Mbps, with:
    • H.264 / AVC Hardware Variable Length Decoding (VLD) - CABAC
    • H.264 / AVC Hardware Variable Length Decoding (VLD) - CAVLC
    • H.264 / AVC Hardware Inverse Transform (IT)
    • H.264 / AVC Hardware Motion Compensation (HWMC)
    • H.264 / AVC Hardware In-Loop Deblocking (ILDB)
  • Support H.264/AVC encode acceleration Main Profile @ L4.1 up to 40 Mbps (excludes GMA X4500HD and HD Graphics).
  • Support JPEG/MJPEG decoding (excludes GMA X4500HD, HD Graphics and HD Graphics 2000/3000).
  • Support Video Post Processing (excludes GMA X4500HD).
