Intel® Media SDK

Intel® Media SDK provides an API to access hardware-accelerated video decode, encode and filtering on Intel® platforms with integrated graphics.

Supported video encoders: HEVC, AVC, MPEG-2, JPEG
Supported Video decoders: HEVC, AVC, VP8, MPEG-2, VC1, JPEG
Supported video pre-processing filters: Color Conversion, Deinterlace, Denoise, Resize, Rotate, Composition

Important note

The current version of Intel Media SDK is compatible with the open source Intel Media Driver for VAAPI. Intel Media SDK depends on LibVA.

Documentation

To get copy of Media SDK documentation use Git* with LFS support.

Please find full documentation under the doc/ folder. Key documents:

Visit our Github Wiki for the detailed setting and building instructions, runtime tips and other information.

You may also wish to visit Intel Media Server Studio support page for additional documentation.

Products which use 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

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-Media-SDK/MediaSDK msdk
cd msdk

To configure and build Media SDK install cmake version 2.8.5 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_OPENCL	ON\|OFF	Enable OpenCL dependent code to be built (default: ON)
ENABLE_X11_DRI3	ON\|OFF	Enable X11 DRI3 dependent code to be built (default: OFF)
ENABLE_WAYLAND	ON\|OFF	Enable Wayland dependent code to be built (default: OFF)
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)
BUILD_TOOLS	ON\|OFF	Build tools (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 GitHub 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

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.
