Intel Media SDK安装步骤

！！！（gcc/g++版本要在4.8以上，本人使用的是5.4版本）

要先安装依赖，按以下步骤依次执行

1.LIBVA

git clone https://github.com/intel/libva.git 
cd libva/ 
./autogen.sh 
./configure 
make 
make install 
cp /usr/local/include/va/* /usr/include/ 
cp /usr/local/lib/libva* /usr/lib64/

2.Intel(R) Graphics Memory Management Library（gmmlib）（可以不用单独安装，安装Media Driver时会附带安装）

Introduction

The Intel(R) Graphics Memory Management Library provides device specific and buffer management for the Intel(R) Graphics Compute Runtime for OpenCL(TM) and the Intel(R) Media Driver for VAAPI.

License

The Intel(R) Graphics Memory Management Library is distributed under the MIT Open Source license.

You may obtain a copy of the License at:

https://opensource.org/licenses/MIT

Building

Get gmmlib repo, make it look like

        <workspace>

    |- GmmLib

$ mkdir <workspace>/build

$ cd <workspace>/build

cmake [-DCMAKE_BUILD_TYPE= Release | Debug | ReleaseInternal] [-DARCH= 64 | 32] ../GmmLib

$ make -j8 ( Also performs compile time ULT)

Build步骤如下:

    mkdir workspace && cd workspace/
    git clone https://github.com/intel/gmmlib.git
    mkdir build && cd build
    cmake [-DCMAKE_BUILD_TYPE= Release] [-DARCH= 64] ../gmmlib
    make -j8

执行完make以后会得到如下结果：

[ 89%] Linking CXX static library libgmm_umd.a
[ 89%] Built target gmm_umd
[ 90%] Linking CXX shared library libigdgmm64.so
[ 90%] Built target igfx_gmmumd_dll
[ 91%] Linking CXX static library libigfx_gmmumd_excite.a
[ 91%] Built target igfx_gmmumd_excite

[ 97%] Linking CXX static library libigfxgmmumd.a
[ 97%] Built target igfxgmmumd

把生成的动态和静态库拷贝到 /usr/lib64 目录下：

cp Source/GmmLib/libgmm_umd.a /usr/lib64/ && 
cp Source/GmmLib/libigdgmm64.so /usr/lib64/ && 
cp Source/GmmLib/libigfx_gmmumd_excite.a /usr/lib64/ && 
cp Source/GmmLib/libigfxgmmumd.a /usr/lib64/

Install

Not a stand alone software component. GmmLib is build as static library for Intel media driver and Compute runtime for OpenCL Supported Platforms

Intel Atom and Core Processors supporting Gen9/Gen10 graphics devices

BDW (Broadwell)

SKL (Skylake)

CNL (Cannonlake)

3.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.

License

The Intel(R) Media Driver for VAAPI is distributed under the MIT license with portions covered under the BSD 3-clause "New" or "Revised" License. You may obtain a copy of the License at: https://opensource.org/licenses/MIT & https://opensource.org/licenses/BSD-3-Clause

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

 1. Build and install libva master
  2. Get gmmlib and media repo and format the workspace folder as below (suggest the workspace to be a dedicated one for media driver build):
<workspace>
    |- gmmlib
    |- media-driver

$ mkdir <workspace>/build_media

$ cd <workspace>/build_media

$ cmake ../media-driver \
-DCMAKE_INSTALL_PREFIX=/usr \
-DMEDIA_VERSION="2.0.0" \
-DBUILD_ALONG_WITH_CMRTLIB=1 \
-DBS_DIR_GMMLIB=`pwd`/../gmmlib/Source/GmmLib/ \
-DBS_DIR_COMMON=`pwd`/../gmmlib/Source/Common/ \
-DBS_DIR_INC=`pwd`/../gmmlib/Source/inc/ \
-DBS_DIR_MEDIA=`pwd`/../media-driver

Alternatively, copy
<workspace>/media-driver/unified_cmake.sh

into
<workspace>/build_media

then run
$ ./unified_cmake.sh

$ 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

Build步骤如下：

    cd workspace/
    git clone https://github.com/intel/media-driver.git
    mkdir build_media && cd build_media/
    cp ../media-driver/unified_cmake.sh ./
    ./unified_cmake.sh 
　　 make -j8
　　 make install

执行unified_cmake.sh脚本时可能会报如下错误：

CMake Error at /usr/local/share/cmake-3.5/Modules/FindPkgConfig.cmake:363 (message):
  A required package was not found
Call Stack (most recent call first):
  /usr/local/share/cmake-3.5/Modules/FindPkgConfig.cmake:528 (_pkg_check_modules_internal)
  cmrtlib/linux/CMakeLists.txt:68 (pkg_check_modules)


-- Configuring incomplete, errors occurred!
See also "/opt/MediaDriver/build_media/CMakeFiles/CMakeOutput.log".

解决方法：

vim /usr/local/share/cmake-3.5/Modules/FindPkgConfig.cmake

在356行，把set(_pkg_check_modules_failed 1)改为set(_pkg_check_modules_failed 0)
再执行./unified_cmake.sh

执行make install后，无错误的情况如下：

Install the project...
-- Install configuration: ""
-- Installing: /home/tvu/hevc_shmenc_new/shmenc/3rdparty/libva-1.8.3/lib/lib/dri/iHD_drv_video.so
-- Installing: /usr/lib64/igfxcmrt64.so
-- Installing: /etc/profile.d/intel-media.sh

命令行输入：echo $LIBVA_DRIVERS_PATH 查看环境变量的值，如下：

/usr/intel/mediasdk/lib64

执行 ls /usr/intel/mediasdk/lib64 可以看到此目录下有如下文件：

iHD_drv_video.so  libmfxhw64-p.so.1.19  libmfxhw64.so  libmfxsw64-p.so.1.19  libmfxsw64.so

iHD_drv_video.so  libdispatch_shared.a  libmfx.a  libmfxhw64-p.so.1.19  libmfxhw64-p.so.1.26  libmfxhw64.so  libmfxsw64-p.so.1.19  libmfxsw64.so  pkgconfig

执行如下命令替换掉 /usr/intel/mediasdk/lib64/iHD_drv_video.so（此步骤也可以在装完MediaSDK后执行）:

cp /$path_to_libva/lib/dri/iHD_drv_video.so  /usr/intel/mediasdk/lib64/

然后执行vainfo的到如下结果：

error: can't connect to X server!
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /usr/intel/mediasdk/lib64/iHD_drv_video.so

      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD

*注意：没替换掉 /usr/intel/mediasdk/lib64/iHD_drv_video.so的情况下，命令行执行vainfo可能会出现以下情况：

error: can't connect to X server!
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /usr/intel/mediasdk/lib64/iHD_drv_video.so
libva error: /usr/intel/mediasdk/lib64/iHD_drv_video.so has no function __vaDriverInit_1_0
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

4.Intel® Media SDK

System requirements

Operating System: Linux

Software:

LibVA
VAAPI backend driver:
Intel Media Driver for VAAPI
Some features require CM Runtime library (part of Intel Media Driver for VAAPI package)

Hardware: Intel platforms supported by the Intel Media Driver for VAAPI

Media SDK test and sample applications may require additional software packages (for example, X Server, Wayland, LibDRM, etc.) to be functional.

How to build

Requirements

Git* (with LFS support)
Perl* v5.16+
Cmake* v2.8+
GCC* v4.8+
LibVA

Build steps

Get sources

git clone https://github.com/Intel-Media-SDK/MediaSDK msdk
cd msdk

使用GCC(默认)编译器配置构建:

perl tools/builder/build_mfx.pl --cmake=intel64.make.release

这时会报如下错误：

CMake Error at builder/FindTrace.cmake:27 (include):
  include could not find load file
    /usr/intel/mediasdk/builder/FindVTune.cmake
Call Stack (most recent call first):
  CMakeLists.txt:56 (include)

解决方法：

mkdir /usr/intel/mediasdk/builder/ 
cp builder/*  /usr/intel/mediasdk/builder/

再执行perl tools/builder/build_mfx.pl --cmake=intel64.make.release即可。

这将构建MSDK二进制文件和MSDK示例。

如果你想配置使用CLang编译器构建，请使用以下命令:

perl tools/builder/build_mfx.pl --cmake=intel64.make.release.clang

构建:

make -j8 -C __cmake/intel64.make.release
