Intel Graphics for Linux* - VAAPI

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).
