Version 3.3 New features Adaptive frame duplication to identify and skip encoding of near-identical frames and signal the duplication info to the decoder via pic_struct SEI. frame-dup to enable frame duplication and --dup-threshold to set the threshold for frame similarity (optional). Boundary aware quantization to cut off bits from frames following scene-cut. This leverages the inability of HVS to perceive fine details during scene changes and saves bits. --scenecut-aware-qp , --scenecut-window and --max-qp-delta to enable boundary aware frame quantization, to set window size (optional) and to set QP offset (optional). Improved scene-cut detection using edge and chroma histograms. --hist-scenecut to enable the feature and --hist-threshold (optional) to provide threshold for determining scene cuts. Enhancements to existing features --hme-range to modify search range for HME levels L0, L1, and L2. Improved performance of AQ mode 4 by reducing memory foot print. Introduced --analysis-save-reuse-level and --analysis-load-reuse-level to de-couple reuse levels of --analysis-save and --analysis-load. Turnaround time of ABR encoding can be reduced by properly leveraging these options. Encoder enhancements Improved VBV lookahead to eliminate blocky artifacts in Intra frames coming towards end of the title. API changes New API function x265_encoder_reconfig_zone() to invoke zone reconfiguration dynamically. Renamed --hdr to --hdr10. --hdr will be deprecated in the upcoming major release. Renamed --hdr-opt to --hdr10-opt. --hdr-opt will be deprecated in the upcoming major release. Additions to x265_param structure to support the newly added features and encoder enhancements. |
