Release v1.14.0 Venetian Duck
2024-01-18 v1.14.0 "Venetian Duck"
This release drops support for old C compilers, such as Visual Studio 2012
and older, that disallow mixing variable declarations and statements (a C99
feature). It adds support for run-time CPU feature detection for Arm
platforms, as well as support for darwin23 (macOS 14).
- Upgrading:
This release is ABI incompatible with the previous release.
Various new features for rate control library for real-time: SVC parallel
encoding, loopfilter level, support for frame dropping, and screen content.
New callback function send_tpl_gop_stats for vp9 external rate control
library, which can be used to transmit TPL stats for a group of pictures. A
public header vpx_tpl.h is added for the definition of TPL stats used in
this callback.
libwebm is upgraded to libwebm-1.0.0.29-9-g1930e3c.
- Enhancement:
Improvements on Neon optimizations: VoD: 12-35% speed up for bitdepth 8,
68%-151% speed up for high bitdepth.
