Libva libva 2.6.1

Supported Platforms

BDW/SKL/APL(BXT)/KBL/CFL/WHL/CML/ICL/EHL/JSL/TGL

Key Improvement:

TGL (TigerLake) open source

TGL feature of this release(This release just include part of TGL media features, will add more features in future releases)

Decoding: enable HEVC&VP9 12-bit, 420/444, HEVC 12bit 422 support , support maximum resolution to 16K (VP9/HEVC 420/422/444), remove VP8 decoding support, enable HEVC real tile to improve almost 2x performance for specific cases.
Encoding: support bigger resolution 16K(HEVC VDEnc), enable random access B for VDEnc HEVC (more flexible GOP structure and better compression rate), enable HEVC 12bit 420 VME encoding. Enable HEVC VDEnc 444 8/10bit speed mode, enable super pipe for B frame performance improvement.
VPP: add more input/output format, including P016 Y216 Y416.
