- Update to version 3.5 New features: * Real-time VBV for ABR (Average BitRate) encodes in –pass 2 using --vbv-live-multi-pass. Improves VBV compliance with no significant impact on coding efficiency. Enhancements to existing features: * Improved hist-based scene cut algorithm: Reduces false positives by leveraging motion and scene transition info. * Support for RADL pictures at IDR scene cuts: Improves coding efficiency with no significant impact on performance. * Bidirectional scene cut aware Frame Quantizer Selection: Saves bits than forward masking with no noticeable perceptual quality difference. API changes: * Additions to x265_param structure to support the newly added features and encoder enhancements. * New x265_param options --min-vbv-fullness and --max-vbv-fullness to control min and max VBV fullness. Bug fixes: * Incorrect VBV lookahead in --analysis-load + --scale-factor. * Encoder hang when VBV is used with slices. * QP spikes in the row-level VBV rate-control when WPP enabled. * Encoder crash in --abr-ladder. - Use new homepage and download URLs. - Add subpackage for HDR10+ library - Add update.sh
