Intel® Media SDK

Intel® Media SDK for Intel Vision Processing Units (VPUs) provides a plain C API to access hardware-accelerated video decode, encode and filtering on VPU graphics hardware platforms. Implementation written in C++ 11.

Supported VPUs: KeemBay
Supported video encoders: HEVC, AVC, JPEG
Supported video decoders: HEVC, AVC, JPEG

Dependencies

• LibVA - an implementation for VA-API (Video Acceleration API).
• VAAPI Bypass - suite of components with an IA host libVA backend and Intel VPU remote proxy application.

How to build

Build steps

Get sources with the following Git* command (pay attention that to get full Media SDK sources bundle it is required to have Git* with LFS support):

git clone https://github.com/intel/MediaSDK-VPU msdk
cd msdk

To configure and build Media SDK install cmake version 3.13 or later and run the following commands:

mkdir build && cd build
cmake ..
make
make install

Media SDK depends on a number of packages which are identified and checked for the proper version during configuration stage. Please, make sure to install these packages to satisfy Media SDK requirements. After successful configuration 'make' will build Media SDK binaries and samples. The following cmake configuration options can be used to customize the build:

Option	Values	Description
API	master|latest|major.minor	Build mediasdk library with specified API. 'latest' will enable experimental features. 'master' will configure the most recent available published API (default: master).
ENABLE_ITT	ON|OFF	Enable ITT (VTune) instrumentation support (default: OFF)
ENABLE_TEXTLOG	ON|OFF	Enable textlog trace support (default: OFF)
ENABLE_STAT	ON|OFF	Enable stat trace support (default: OFF)
BUILD_ALL	ON|OFF	Build all the BUILD_* targets below (default: OFF)
BUILD_RUNTIME	ON|OFF	Build mediasdk runtime, library and plugins (default: ON)
BUILD_SAMPLES	ON|OFF	Build samples (default: ON)
BUILD_TESTS	ON|OFF	Build unit tests (default: OFF)
MFX_VSI_HDDL	ON|OFF	Enable or disable HDDL support (default: ON)
USE_SSH_FOR_BYPASS	ON|OFF	ON - Use SSH protocol to checkout external project dependencies OFF - HTTPS one (default: OFF)

The following cmake settings can be used to adjust search path locations for some components Media SDK build may depend on:

Setting	Values	Description
CMAKE_ITT_HOME	Valid system path	Location of ITT installation, takes precendence over CMAKE_VTUNE_HOME (by default not defined)
CMAKE_VTUNE_HOME	Valid system path	Location of VTune installation (default: /opt/intel/vtune_amplifier)

Visit our Github Wiki for advanced topics on setting and building Media SDK.

Enabling Instrumentation and Tracing Technology (ITT)

To enable the Instrumentation and Tracing Technology (ITT) API you need to:

• Either install Intel® VTune™ Amplifier
• Or manually build an open source version (see IntelSEAPI for details)

and configure Media SDK with the -DENABLE_ITT=ON. In case of VTune it will be searched in the default location (/opt/intel/vtune_amplifier). You can adjust ITT search path with either CMAKE_ITT_HOME or CMAKE_VTUNE_HOME.

Once Media SDK was built with ITT support, enable it in a runtime creating per-user configuration file ($HOME/.mfx_trace) or a system wide configuration file (/etc/mfx_trace) with the following content:

Output=0x10

Configuration

Please refer to Media SDK User Guide.

Recommendations

• In case of GCC compiler it is strongly recommended to use GCC version 6 or later since that's the first GCC version which has non-experimental support of C++11 being used in Media SDK.
