Intel(R) Media Driver for VAAPI

Introduction

The Intel(R) Media Driver for VAAPI is a new VA-API (Video Acceleration API) user mode driver supporting hardware accelerated decoding, encoding, and video post processing for GEN based graphics hardware.

Prerequisites

For Ubuntu 16.04 and above

# apt install autoconf libtool libdrm-dev xorg xorg-dev openbox libx11-dev libgl1-mesa-glx libgl1-mesa-dev

Equivalents for other distributions should work.

Dependencies

Libva - https://github.com/intel/libva

GmmLib - https://github.com/intel/gmmlib (please check https://github.com/intel/media-driver/wiki/Comparability-with-GmmLib)

Building

Build and install libva master
Build and install gmmlib master
Get media repo and format the workspace folder as below (suggest the workspace to be a dedicated one for media driver build):

<workspace>
    |- media-driver

$ mkdir <workspace>/build_media

$ cd <workspace>/build_media

$ cmake ../media-driver

$ make -j8

Install

$ sudo make install

This will install the following files (e.g. on Ubuntu):

-- Installing: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
-- Installing: /etc/profile.d/intel-media.sh
-- Installing: /usr/lib/x86_64-linux-gnu/igfxcmrt64.so

For iHD_drv_video.so please export related LIBVA environment variables.

export LIBVA_DRIVERS_PATH=<path-contains-iHD_drv_video.so>
export LIBVA_DRIVER_NAME=iHD

Build Modes

This section summarizes key driver build modes which can be used in the different environment requirements:

Build option	Default value	Dependencies	Comments
ENABLE_KERNELS	ON	N/A	Enable/Disable shaders during driver build
ENABLE_NONFREE_KERNELS	ON	ENABLE_KERNELS=ON	Enable/disable close source shaders (kernels) during the build
BUILD_KERNELS	OFF	ENABLE_KERNELS=ON, ENABLE_NONFREE_KERNELS=OFF	If enabled, rebuild open source shaders (kernels) from sources. Requires ENABLE_NONFREE_KERNELS=OFF

With the above options it is possible to build (table assumes that non-listed options have default values):

No.	Build option(s)	HW Features	Shaders (Kernels)	Comments
1	ENABLE_KERNELS=ON	Yes	Close source (pre-built)	Default, full feature driver
2	ENABLE_KERNELS=OFF	Yes	None	HW features only, include HW decoder, HW VDEnc Encoder (CQP mode)
3	ENABLE_NONFREE_KERNELS=OFF	Yes	Open source (pre-built)	HW features available in prev. mode (ENABLE_KERNELS=ON) and features supported by open source shaders
4	ENABLE_NONFREE_KERNELS=OFF BUILD_KERNELS=ON	Yes	Open source	Same as ENABLE_NONFREE_KERNELS=OFF driver, but shaders are rebuilt from sources
