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 Media SDK Support Matrix for more information.

Intel® Media SDK

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 Media SDK Support Matrix

    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 features got dropped). New GPU supported by Runtime loaded by libmfx.so.1 GPU Type libmfxhw64.so.1 libmfx-gen.so.1.2 libmfxhw64.so.1 libmfx-gen.so.1.2 BDW (Broadwell) Legacy ✔ ✔ SKL (Skylake) Legacy ✔ ✔ BXT (Broxton) Legacy ✔ ✔ APL (Apollo Lake) Legacy ✔ ✔ KBLx [1] Legacy ✔ ✔ ICL (Ice Lake) Legacy ✔ ✔ JSL (Jasper Lake) Legacy ✔ ✔ EHL (Elkhart Lake) Legacy ✔ ✔ TGL (Tiger Lake) Legacy ✔ ✔ ✔ DG1 (Xe MAX) Legacy ✔ ✔ ✔ SG1 Legacy ✔ ✔ RKL (Rocket Lake) Legacy ✔ ✔ ✔ ADL-S (Alder Lake S) VPL ✔ ✔ ADL-P (Alder Lake P) VPL ✔ ✔ Future platforms...

    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
      

    Dependencies

    Intel Media SDK depends on Intel Media Driver for VAAPI.

    Products which use Media SDK

    Use Media SDK via popular frameworks:

    • ffmpeg-qsv plugins
    • gst-plugins-bad

    Learn best practises and borrow fragments for final solutions:

    • 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.
    • System requirements

      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 Intel Media Driver for VAAPI
    • Some features require CM Runtime library (part of 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.

      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 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) USE_SYSTEM_GTEST ON|OFF Use system gtest version instead of bundled (default: OFF) BUILD_TOOLS ON|OFF Build tools (default: OFF) MFX_ENABLE_KERNELS ON|OFF Build mediasdk with 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]( Enabling Instrumentation and Tracing Technology (ITT)

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

      • Either install 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
      

      Known limitations

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

      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.
