Release Notes
Version 3.1
Release date - 18th June, 2019.
New features
1. x265 can invoke SVT-HEVC library for encoding through :option:`--svt`.
2. x265 can now accept interlaced inputs directly (no need to separate
fields), and sends it to the
encoder with proper fps and frame-size through :option:`--field`.
3. :option:`--fades` can detect and handle fade-in regions. This option
will force I-slice and
initialize RC history for the brightest frame after fade-in.
API changes
1. A new flag to signal MasterDisplayParams and maxCll/Fall separately
Encoder enhancements
1. Improved the performance of inter-refine level 1 by skipping the
evaluation of smaller CUs when
the current block is decided as "skip" by the save mode.
2. New AVX2 primitives to improve the performance of encodes that enable
:option:`--ssim-rd`.
3. Improved performance in medium preset with negligible loss in quality.
Bug fixes
1. Bug fixes for zones.
2. Fixed wrap-around from MV structure overflow occurred around 8K pixels
or over.
3. Fixed issues in configuring cbQpOffset and crQpOffset for 444 input
4. Fixed cutree offset computation in 2nd pass encodes.
Known issues
1. AVX512 main12 asm disabling.
2. Inconsistent output with 2-pass due to cutree offset sharing.
