This adds and improves several vp9 controls. 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.
