Complete Version history / Release notes / Changelog / What's New for AV1vfw
v2.30 2025.02.02.
- updated svt-av1 encoder to v2.3.0, modified encoder options (derived list from svt-av1 app)
- updated libdav1d decoder to 1.5.1
- updated FFmpeg library to 6.1.2
- updated compiler to MinGW-w64 12.2
- added Fast Decode GUI option (equal to --fast-decode 2) (dialog.c, codec.c, config.c)
- added Zero Latency GUI option (equal to --pred-struct 1) (can cause visible quality loss) (dialog.c, codec.c)
- corrected decoder side (added low delay flag to FFmpeg) (decode.c)
- corrected pixel-format and required (16) padding conversions (codec.c)
- extended preset (speed vs quality) numbers to 10, default is 8 (higher settings may have major quality issues) (codec.c, config.c)
v0.85 2020.10.23.
- updated svt-av1 encoder lib to v0.8.5+ (git 20201020), improved speed, quality and stability; modified encoder options
- updated libdav1d decoder to 0.7.1
- updated compiler to MinGW-w64 10.2
- added / modified "Enable AVX512 instruction set" switch
- removed Slow 1st pass selection, because svt-av1 always uses Fast 1st pass mode (and it's not configurable)
- removed manual "Create stat file" switch (stat file is made for 1st pass execution only)
- workarounds for some svt-av1 problems (less crash)
- added temporary svt-av1 limitation (to avoid hang up): --irefresh-type is always 2 (IDR, Closed GOP)
v0.82 2020.04.19.
