Release date - 29th May, 2020.

New features

  • Edge-aware quadtree partitioning to terminate CU depth recursion based on edge information. --rskip level 2 enables the feature and --rskip-edge-threshold denotes the minimum expected edge-density percentage within the CU, below which the recursion is skipped. Experimental feature.
  • Application-level feature --abr-ladder for automating efficient ABR ladder generation. Shows ~65% savings in the over-all turn-around time required for the generation of a typical Apple HLS ladder in Intel(R) Xeon(R) Platinum 8280 CPU @ 2.70GHz over a sequential ABR-ladder generation approach that leverages save-load architecture.

Enhancements to existing features

  • Improved efficiency in 2-pass rate-control algorithm. The savings in the bitrate is ~1.72% with visual improvement in quality in the initial 1-2 secs.

Encoder enhancements

  • Faster ARM64 encodes enabled by ASM contributions from Huawei. The speed-up over no-asm version for 1080p encodes @ medium preset is ~15% in a 16 core H/W. Strict VBV conformance in zone encoding.

Bug fixes

  • Multi-pass encode failures with --frame-dup.
  • Corrupted bitstreams with --hist-scenecut when input depth and internal bit-depth differ.
  • Incorrect analysis propagation in multi-level save-load architecture.
  • Failure in detecting NUMA packages installed in non-standard directories.
