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

To get copy of Media SDK documentation use Git* with LFS support.
Please find full documentation under the
doc/ folder. Key documents:
- Media SDK Developer Reference
- Media SDK Developer Reference Extensions for User-Defined Functions
- Media Samples Guide
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
Operating System: Linux
- VAAPI backend driver:
- 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
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:
|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_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:
|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:
- 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.
