- 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
$ 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

Intel(R) Media Driver for VAAPI is recommended to be built against gcc compiler v6.1 or later, which officially supported C++11.
-
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
-
HuC firmware is needed for AVC low power encoding bitrate control, including CBR, VBR, etc. As of now, HuC firmware support is disabled in Linux kernels by default. Please, refer to i915 kernel mode driver documentation to learn how to enable it. Mind that HuC firmware support presents in the following kernels for the specified platforms:
- APL/KBL: starting from kernel 4.11
- CFL: starting from kernel 4.15
-
ICL: preliminary support and may not be fully functional. It requires Linux kernel 4.17+ loaded with i915.alpha_support=1 parameter to be tried.
-
ICL encoding has two known issues:
- Low power encoding: known issue#328 needs kernel patch which is under review.
- VME based encoding: known issue#267, which requires media driver patch PR#271 and kernel driver patch Per context dynamic (sub)slice power-gating.
