This release of Intel® Media SDK is part of Intel® Media Server Studio 2018 R2 release.

  • Whats new:

    • OS and hardware support

      • CentOS 7.4. The release supports original 3.10.0-693.17.1.el7.x86_64 kernel of CentOS 7.4.
      • The release contains a set of patches for open source components on top of 4.14.20 kernel suitable for other variants of Linux OSes.
    • SDK API 1.27

      • Added mfxExtFeiHevcRepackCtrl, mfxExtFeiHevcRepackStat for HEVC FEI ENCODE repacking control and status report.
      • Added mfxExtAVCRoundingOffset for AVC Encode rounding offset control.
    • Multi-Frame Encode

      • H.264 FEI ENCODE support is added.
      • Performance improved for Xeon E3 1200 v5 Family.
      • Added dynamic slice shutdown support
      • Improved performance for 1:N workloads when different frame rates present in pipeline.
    • H.264 encode

      • Scene Change Detection (SCD) feature for improved BRC Rate handling and quality improvement.
        • Scene Change Detection feature is enabled when mfxExtCodingOption2::ExtBRC is ON.
        • Added AdaptiveI & AdaptiveB encoding functionality using SCD
        • Added adaptive PRefType=2 encoding functionality using SCD.
        • Limited to CBR/VBR, progressive and display order encoding.
      • Adaptive Long Term Reference (LTR) Coding Feature for compression efficiency and quality improvement.
        • Adaptive LTR coding feature is enabled when mfxExtCodingOption2::ExtBRC is ON and extended buffer MFX_EXTBUF_BRC is not set.
        • AdaptiveI, AdaptiveB and PRefType=2 are enabled when mfxExtCodingOption2::ExtBRC is ON and extended buffer MFX_EXTBUF_BRC is not set.
        • Adaptive LTR coding can be disabled using mfxExtCodingOption3::ExtBRCAdaptiveLTR.
        • Limited to CBR/VBR, progressive and display order encoding.
      • [41854] Support customized rounding offset control for encoding quantization. User might customize the rounding offset to achieve better encoding quality.
    • HEVC encode

      • Hardware HEVC Encoder merged back to library, plugin interface now optional, but remains for backward compatiblity.
    • HEVC FEI

      • [40651] Support multi-pass PAK for HEVC FEI Encode, and repack status reporting.
    • VPP

      • Motion compensated temporal filtering [MCTF] support.
    • Changes in behavior compared to Media Server Studio 2018 R1 - SDK:

      • Intel Media SDK and Driver are not compatible with previously released versions of Intel Media Server Studio - Essentials and Professional Editions including HEVC Decode plug-in, HEVC Encode plug-in, HEVC GPU Accelerated Encode plug-in, Premium Telecine Interlace Reverser plug-in, etc.
      • MPEG-2 encode:
        • [37189] Previously Query() function with MFX_RATECONTROL_AVBR mode in input parameters returned MFX_RATECONTROL_VBR. The logic is removed in this release.
      • VPP:
        • [35218] VPP resize of interlaced streams may produce output that is not bit-exact with output of previous release.
    • Additional limitations specific for open source release:

      • SW fallback is unsupported for all components.
      • Rotation is not supported.
