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.
Libva - https://github.com/01org/libva
GmmLib - https://github.com/intel/gmmlib
- Build and install libva master commit df544cd5a31e54d4cbd33a391795a8747ddaf789
- Get gmmlib and media repo and format the workspace folder as below:
<workspace>
|- gmmlib
|- media-driver
$ mkdir <workspace>/build
$ cd <workspace>/build
$ cmake ../media-driver \
-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
then run
$ ./unified_cmake.sh
$ make -j8
$ sudo make install
This will install the following files:
-- 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
Note that ‘make install’ only supports Ubuntu at this time. For other distributions, please locate the following files:
<workspace>/build/media_driver/iHD_drv_video.so
<workspace>/build/cmrtlib/linux/igfxcmrt64.so
and copy them to proper system path (instead of using ‘make install’ directly).
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

SKL: Green or other incorrect color will be observed in output frames when using YV12/I420 as input format for csc/scaling/blending/rotation, etc. on Ubuntu 16.04 stock (with kernel 4.10). The issue can be addressed with the kernel patch: WaEnableYV12BugFixInHalfSliceChicken7 commit 0b71cea29fc29bbd8e9dd9c641fee6bd75f6827
