Comment (by bdubbs):
Version 3.0
Release date - 23/01/2019
New features
1. option:: '--dolby-vision-profile <integer|float>' generates bitstreams
confirming to the specified Dolby Vision profile. Currently profile 5,
profile 8.1 and profile 8.2 enabled, Default 0 (disabled)
2. option:: '--dolby-vision-rpu' File containing Dolby Vision RPU
metadata. If given, x265's Dolby Vision metadata parser will fill the RPU
field of input pictures with the metadata read from the file. The library
will interleave access units with RPUs in the bitstream. Default NULL
(disabled).
3. option:: '--zonefile <filename>' specifies a text file which contains
the boundaries of the zones where each of zones are configurable.
4. option:: '--qp-adaptation-range' Delta-QP range by QP adaptation based
on a psycho-visual model. Default 1.0.
5. option:: '--refine-ctu-distortion <0/1>' store/normalize ctu distortion
in analysis-save/load. Default 0.
6. Experimental feature option:: '--hevc-aq' enables adaptive quantization
It scales the quantization step size according to the spatial activity
of one coding unit relative to frame average spatial activity. This AQ
method utilizes
the minimum variance of sub-unit in each coding unit to represent the
coding unit’s spatial complexity.
Encoder enhancements
1. Preset: change param defaults for veryslow and slower preset. Replace
slower preset with defaults used in veryslow preset and change param
defaults in veryslow preset as per experimental results.
2. AQ: change default AQ mode to auto-variance
3. Cutree offset reuse: restricted to analysis reuse-level 10 for
analysis-save -> analysis-load
4. Tune: introduce --tune animation option which improves encode quality
for animated content
5. Reuse CU depth for B frame and allow I, P frame to follow x265 depth
decision
Bug fixes
1. RC: fix rowStat computation in const-vbv
2. Dynamic-refine: fix memory reset size.
3. Fix Issue #442: linking issue on non x86 platform
4. Encoder: Do not include CLL SEI message if empty
5. Fix issue #441 build error in VMAF lib
