DISCONTINUATION OF PROJECT.

This project will no longer be maintained by Intel.

This project has been identified as having known security escapes.

Intel has ceased development and contributions including, but not limited to, maintenance, bug and security fixes, new releases, or updates, to this project.

Intel no longer accepts patches to this project.

If you have an ongoing need to use this project, are interested in independently developing it, or would like to maintain patches for the open source software community, please create your own fork of this project.

For continued support and access to new features, Intel® Media SDK users are encouraged to read the transition guide on upgrading from Intel® Media SDK to Intel® oneAPI Video Processing Library (oneVPL), and to move to oneVPL as soon as possible.

Please also refer to the Media SDK Support Matrix for more information.

Intel® Media SDK provides a plain C API to access hardware-accelerated video decode, encode and filtering on Intel® Gen graphics hardware platforms. Implementation written in C 11 with parts in C-for-Media (CM).

Supported video encoders: HEVC, AVC, MPEG-2, JPEG, VP9

Supported video decoders: HEVC, AVC, VP8, VP9, MPEG-2, VC1, JPEG, AV1

Supported video pre-processing filters: Color Conversion, Deinterlace, Denoise, Resize, Rotate, Composition

Media SDK is a part of Intel software stack for graphics:

• Linux Graphics Drivers - General Purpose GPU Drivers for Linux* Operating Systems
  • Visit documentation for instructions on installing, deploying, and updating Intel software to enable general purpose GPU (GPGPU) capabilities for Linux*-based operating system distributions.

Pay attention that Intel® Media SDK lifetime comes to an end in a form it exists right now. In particular,

• API 1.35 is projected to be the last API of 1.x API series
• Runtime library (libmfxhw64.so.1) is not planned to get support of new Gen platforms

All future development is planned to happen within oneVPL library and its runtime implementations which are direct successors of Intel® Media SDK. oneVPL introduces API 2.x series which is not backward compatible with API 1.x series (some features got dropped). New VPL Runtime for Gen Graphics (libmfx-gen.so.1.2) comes with the support of new Gen platforms.

Pay attention that Intel® Media SDK has forward compatibility with new VPL runtime (libmfx-gen.so.1.2) in the scope of API features supported by both 1.x and 2.x API series. As such, if application is built against Intel® Media SDK, it still can work on new platforms. For that purpose Media SDK Dispatcher loads either Media SDK Legacy Runtime (libmfxhw64.so.1) or VPL Runtime (libmfx-gen.so.1.2) depending on the underlying platform. See support matrix below.

Notes:

• [1] KBLx is one of: KBL (Kaby Lake), CFL (Coffe Lake), WHL (Whiskey Lake), CML (Comet Lake), AML (Amber Lake)

• [2] On the multi GPU system which has both "Legacy" and "VPL" GPUs Media SDK Dispatcher loads Media SDK Legacy Runtime (libmfxhw64.so.1) by default. VPL Runtime (libmfx-gen.so.1.2) or Media SDK Runtime (libmfxhw64.so.1) can be explicitly selected via the following environment variable:

  export INTEL_MEDIA_RUNTIME=ONEVPL  # for VPL Runtime: libmfx-gen.so.1.2
  or
  export INTEL_MEDIA_RUNTIME=MSDK    # for Media SDK Runtime: libmfxhw64.so.1
  

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

Use Media SDK via popular frameworks:

• FFmpeg via ffmpeg-qsv plugins
• GStreamer via plugins set included into gst-plugins-bad

Learn best practises and borrow fragments for final solutions:

• https://github.com/intel/media-delivery
  • This collection of samples demonstrates best practices to achieve optimal video quality and performance on Intel GPUs for content delivery networks. Check out the demo, recommended command lines and quality and performance measuring tools.

Use Media SDK via other Intel products:

• OpenVINO Toolkit
  • This toolkit allows developers to deploy pre-trained deep learning models through a high-level C Inference Engine API integrated with application logic.
• Open Visual Cloud
  • The Open Visual Cloud is a set of open source software stacks (with full end-to-end sample pipelines) for media, analytics, graphics and immersive media, optimized for cloud native deployment on commercial-off-the-shelf x86 CPU architecture.

Operating System:

• Linux x86-64 fully supported
• Linux x86 only build
• Windows (not all features are supported in Windows build - see Known Limitations for details)

Software:

• `LibVA https://github.com/intel/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.

Operating System: Windows (experimental)

Requires Microsoft Visual Studio 2017 for building.

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 3.6 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:

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

Visit our [Github Wiki](https://github.com/Intel-Media-SDK/MediaSDK/wiki) for advanced topics on setting and building Media SDK.

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

Windows build contains only samples and dispatcher library. MediaSDK library DLL is provided with Windows GFX driver.

• 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.
