1.3a

This pre-release of open source Intel® Media SDK features Media Server Studio 2018 R1 and CentOS 7.4 support. Release highlights available at Intel® Developer Zone article.

Whats new comparing to 1.2a:

• API 1.25
• Enhances AVC compression efficiency and video quality features
• Improves HEVC encode video quality and CPU utilization for multiple media sessions running simultaneously
• Enabled setting the NALU type for HEVC encoder order mode
• Enabled the interlaced content encoding for HEVC
• Increases performance significantly for Sessions Joining API
• Enabled VPP Deinterlacer to handle content that alternates between Progressive/Interlaced frame, Top Field First (TFF) and Bottom Field First (BFF)
• Supports CentOS 7.4 - providing new features, security updates
• Enhanced FEI capabilities:
  • Improved video quality with fade in/fade out by applying multiplicative weighting factor and an additive offset to the motion compensated prediction
  • Enabled the number of repack passes report for H.264 to help bitrate control tuning
  • Added P/I field encoding (first field as P field, second field as I field) to improve quality
• Preview functionality added to this release Multi-Frame encode APIs:
  • Multi-Frame encode APIs support added helping to improve transcoding dencity in multi-stream scenario, following known limitations apply to current implementation:
  • Only H264 Encode is supported at a moment
  • Optimized only for Xeon E3 1500 v5 series
  • Performance can be worse than usual single-frame in next known cases:
    • 4K resolution encoding
    • N:N with HEVC decode present in pipeline
    • cases where framerates differs significantly like 30 and 60 for different streams
  • Following functionality is not supported with multi-frame encode operation and when set, multiframe will be disabled:
    • When number of slices is controlled by parameters NumSlice, NumSliceI, NumSliceP, NumSliceB.
    • ‘intra refresh’ parameters are not supported.

The current version of Intel Media SDK is only compatible with the Linux* Graphics Driver from Intel® Media Server Studio for Linux*. You need to download and install Intel Media Server Studio 2018 R1 before you build this version of Intel Media SDK. Intel Media SDK depends on a special version of LibVA which comes with Intel Media Server Studio installation and is not in upstream, so this version is not compatible with the LibVA/driver available at 01.org.

Additinal limitations specific for open source release:

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

1.2a

This pre-release of open source Intel® Media SDK features MSS 2017 R3 and CentOS 7.3 support. Release highlights available at Intel® Developer Zone article.

Whats new comparing to 1.1:

• Added User-Defined Bitrate Control support
• C++ 11 support
