What's new Media SDK 20.1.0:

API 1.32

• Added Screen Content Coding (SCC) support to HEVC

HEVC encode

• Component received major refactoring which limited cyclomatic complexity and made codec feature set composable
• Enabled Sliding Window support
• Enabled Weighted Prediction support
• Enabled Fade Detection support
• Fixed per-macroblock QP setting (MBQP)

VP9 encode

• Stability improvement

AVC encode

• Enable arbitrary reference field polarity on Broadwell and Skylake
• Following attributes calculated based on media-driver capabilities instead of harcoded values:
• Supported color formats: 8-bit only, 10-bit

MPEG-2 encode

• Following attributes calculated based on media-driver capabilities instead of harcoded values:
• Picture size limits
• Frame skip support
• Slice structure

HEVC decode

• Added support for SCC

VP9 decode

• Improved DRC handling

VPP

• Fixed Motion-Compensated Temporal Filter (MCTF) on Icelake
• Added mirroring support on Tigerlake

Samples

• Improved 12-bit format support
• Added command line option which force use fixed function (low-power) version of components where available
• Documented ROI file format for sample_multi_transcode
• Added BitrateLimit to command line option
• Metrics Monitor let user specify a path to gfx device

Misc

• Transient media surfaces used to perform system to gpu copying now allocated internally, bypassing user-supplied allocator
• Build: version stored in root CMakeFile.txt, allowing suffix customization using MEDIA_VERSION_EXTRA define

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 20.1 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.

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 Tigerlake, Elkhartlake and Jasperlake platforms is preliminary and may not be fully functional
• SW fallback is unsupported for all components but MJPEG

HEVC encode

• Added support for 12-bit range extensions (TGL+)

VP9 encode

• Stability improvement

AVC encode

• Improved bit rate control

VP9 decode

• Improved DRC handling

VPP

• Removed shallow copy
• Fixed Chroma Siting (#1737)
