vvenc-1.9.1-rc1
Bugfix release:
- fixed problems with 8-bit encoding, especially for 10-bit input
- improvements to rate control, especially spatial sub-sampling for first pass
- added medium_lowDecEnergy as a built-in preset
- many other fixes
vvenc-1.9.0
- added rate capping during rate control (must be at least 1.5x of target rate)
- extensive improvements and cleanups to rate control, especially single pass (improved efficiency by 1-2%)
- speedup of first pass, especially for preset faster (around 15% overall runtime), using spatio-temporal downsampling
- unified MCTF activation for low- and high-rate encoding
- various speedups, fixes, and cleanups
vvenc-1.9.0-rc3
Over 1.9.0-rc2:
- reduce single pass rate control deviation from given target bit-rate, when intra period is not a multiple of gop size (see #296)
Over 1.9.0-rc1:
- propagating missing data required for efficient RC in fast/faster presets when using QPA (bugfix)
Over 1.8.0:
- added rate capping during rate control (must be at least 1.5x of target rate)
