What's new Media SDK 19.2.0:

• API 1.30

  • Added content protection, currently Android only

• HEVC encode

  • Added QVBR support
  • Added HDR SEI
  • Enabled ICQ/VCM bitrate control support
  • Improved driver caps handling

• AVC encode

  • Fixed AVC encoding error on some values of mfxExtCodingOption2::NumMbPerSlice #864.
  • Improved driver caps handling

• Code changes

  • Fixed incorrect structure initialization code (see #1398 for details)

• Software requirements

  • Libdrm 2.4.84 or later
  • Kernel 4.14 or later (4.19 or later is recommended, 5.2 or later required for Icelake)

• Hardware requirements

  • Actualized device ID whitelist

• Misc

  • Windows dispatcher and samples upstreamed
  • Many minor improvements especially for gen11 features
  • Improved PMU metrics reporting in metrics_monitor
  • This release focuses on versatility and absence of technical debt in i915 driver. Downside of this approach is suboptimal performance and quality in certain usages comparing to Media Server Studio on Broadwell and Skylake platforms.
  • Decoders robustness on corrupted content on Apollo Lake, Kabylake, Coffeelake is a bit lower comparing to Broadwell and Skylake.

• Known issues

  • Kernel 5.0 have known issue with endurance on Skylake see https://bugs.freedesktop.org/show_bug.cgi?id=110285 for details.
  • Media Stack 19.2 with Linux kernel 5.0 may cause higher CPU usage and instability in endurance testing. Issue root caused to media driver see intel/media-driver#671 for details. Recommend kernel 4.19.5 not affected by this issue.

• Limited support on certain platforms:

  • MPEG-2 encode is not supported on Apollo Lake
  • H.264 Flexible Encode Infrastructure only supported on Broadwell and Skylake
  • Multi Frame Encode (MFE), HEVC Flexible Encode Infrastructure only supported on Skylake
  • VP9 decoder is only supported on Kabylake, Coffeelake and Icelake
  • VP9 encoder is only supported on Icelake platform
  • Support for Icelake platform is preliminary and may not be fully functional
  • SW fallback is unsupported for all components but MJPEG
