Most are related to SVC: + VP9E_SET_SVC_FRAME_DROP_LAYER: + - Frame dropping in SVC. + VP9E_SET_SVC_INTER_LAYER_PRED: + - Inter-layer prediction in SVC. + VP9E_SET_SVC_GF_TEMPORAL_REF: + - Enable long term temporal reference in SVC. + VP9E_SET_SVC_REF_FRAME_CONFIG/VP9E_GET_SVC_REF_FRAME_CONFIG: + - Extend and improve this control for better flexibility in setting SVC + pattern dynamically. + VP9E_SET_POSTENCODE_DROP: + - Allow for post-encode frame dropping (applies to non-SVC too). + VP9E_SET_SVC_SPATIAL_LAYER_SYNC: + - Enable spatial layer sync frames. + VP9E_SET_SVC_LAYER_ID: + - Extend api to specify temporal id for each spatial layers. + VP9E_SET_ROI_MAP: + - Extend Region of Interest functionality to VP9. + + - Enhancements: + 2 pass vp9 encoding has improved substantially. When using --auto-alt-ref=6, + we see approximately 8% for VBR and 10% for CQ. When using --auto-alt-ref=1, + the gains are approximately 4% for VBR and 5% for CQ. + + For real-time encoding, speed 7 has improved by ~5-10%. Encodes targeted at + screen sharing have improved when the content changes significantly (slide + sharing) or scrolls. There is a new speed 9 setting for mobile devices which + is about 10-20% faster than speed 8. + + - Bug fixes: + VP9 denoiser issue. + VP9 partition issue for 1080p. + VP9 rate control improvments. + Postprocessing Multi Frame Quality Enhancement (MFQE) issue. + VP8 multithread decoder issues. + A variety of fuzzing issues. + 2018-01-04 v1.7.0 "Mandarin Duck" This release focused on high bit depth performance (10/12 bit) and vp9 encoding improvements. |
