2018-06-14Separate GF structure defining from bit allocationZoe Liu
This CL separates the defining of the GF group structure from the handling of its bitrate allocation. The encoder performance should stay unchanged. Change-Id: Ib77967757702bb4b284034e429d4c41ae86d0838

2018-06-14Add temporal model control as a speed featureJingning Han
The model construction would incur 15% slowdown for speed 2. The speed change on speed 0 is unnoticeable. The current speed features set up would DISABLE temporal dependency model for all speed settings. Change-Id: Ic45dd962f3a54a8f5f0452502dc05e352dc09ca1

2018-06-11vp9 svc: Denoise golden when it's a temporal ref.Jerome Jiang
When golden was the inter-layer reference, a block that selected the golden ref would not be denoised. But when golden is used as a second temporal reference then we should denoise blocks that select the golden reference. This changes allows for that.

2018-06-11vp9-svc: Fix to frames_since_golden update for SVC.Marco Paniconi
When the second (gf) temporal reference is used in SVC: the reference is refreshed on base TL superframes, and so the rc->frames_since_golden counter was also only updated on base TL frames. But this was disabling the golden reference from being used as a temporal reference for TL > 0 frames (since frames_since_golden was 0/not updated on TL > 0 frames). Fix is to copy the update of rc->frames_since_golden to all upper temporal layers. This allows TL > 0 frames to test the golden inter mode. Gain on RTC set: ~2%, ~8% on desktop_vga clip. Encode time increase ~5-8% on linux, 3SL-3TL run with 1 thread. For now keep this off for TL > 0 frames in speed features, so this change does not change current behavior for speed >= 7.

2018-06-08Small speedup of ml_pruning_partition()Hui Su
Terminate early and skip neural net model when linear score is already high enough, which indicates that we should not skip split and rectangular partitions. No changes on compression; encoding speed improves slightly. Change-Id: I4e0995090200eb4889344da905d2f7048673af5f

2018-06-07vp9-svc: Adjust some logic on gf temporal reference.Marco Paniconi
For the feature of using second temporal reference (when inter-layer is off): move the buffer_idx assignement and refresh flag settings further down to vp9_rc_get_svc_params(), since is_key_frame is set there for every frame/layer. Otherwise it was using the setting from the previous frame/layer. This makes the refresh more consistent for both layers for 2 spatial layers case. Small/negligible change in metrics.

2018-06-07vp9-svc: Allow second temporal reference for next highest layer.Marco Paniconi
When inter-layer prediction is disabled on INTER frames, allow for next highest resolution to have second temporal reference. Current code allowed for only top/highest spatial layer. Change-Id: I102137273e3e4d57512a13d95e8ccb9c5b0a7b4b

2018-06-06vp9-svc: Modify choose_partitioning for second temporal refMarco Paniconi
For mode where second temporal reference is used in SVC: allow for using/testing this reference (golden ref) in the variance partition scheme (choose_partitioning). Small positive gain (~0.25%) on metrics for 3 layer SVC, negligible change in speed. Change-Id: I29b8315da530e60db3d6c90faa8fb178d9f2de26

2018-06-06vp9-svc: Enable use of second temporal reference for SVC.Marco Paniconi
When inter-layer is disabled on INTER frames, this will allow use of a second (longer term) temporal reference for SVC. Only enabled on highest resolution spatial layer. Average gains of ~4% on RTC set, speed decrease of about ~2%. Change-Id: I3c2d415653c448eb7269c828e120fe8bb2ef3f97
2018-06-06vp9-svc: Add a buffer_idx is_used parameter for SVC.Marco Paniconi
For the case where a second (long term) temoral reference is used in the SVC: this additional parameter is to make sure the buffer slot selected for this reference is available for usage, i.e., it is never used for any of the 3 references set for the fixed SVC patterns. And some code cleanup (replace cpi->svc). No change in behavior. Change-Id: Icba46edfbbefb94d5ea8e2d5c24cccd85a406ee6

2018-06-05vp9: Move up reset of cyclic refresh under dynamic resize.Jerome Jiang
When resize happens and cyclic refresh is not applied on the current (resized) frame, the sb_index is not reset and then might be out of boundary on future frames when the cyclic refresh is applied. Change-Id: I05282fc4bc2323522d60e019ed0790d69221a2f7
2018-06-04vp9-svc: Allow usage of second (long term) temporal reference.Jerome Jiang
Allow for second temporal reference for top spatial layer in SVC, when inter-layer prediction is disabled on INTER frames. The second temporal reference is labelled as the golden reference and the update/refresh of this reference buffer is only on base temporal layer superframes. For now the period of refresh is fixed at every 20 TL0 superframes. Average gain is ~4% on RTC set, several clips up by ~8-12%. Speed loss is about ~2% on mac. Feature is disabled as default for now.

2018-05-31VP9: Allow for bilinear subpel interp at speed 9 for high motion.Jerome Jiang
Fixed some settings in nonrd pick mode to allow for frame-level bilinear to be set. On Galaxy S8+ it has 4% speed up on high motion clips. Almost the same for low motion. 0.17% quality loss on RTC. Change-Id: I044a7de020183754ba08bb6c96c5a78ba5c7fea2

2018-05-31vp9-svc: Fix to some frame metrics for real-time mode.Marco Paniconi
Add condition of LAST frame to the consec_zeromv and avg_frame_low_motion metrics. This is needed for SVC as the golden reference is a spatial reference and should not be included in the metric computation. Small/negligible change in metrics on RTC set. Change-Id: I6ea16298fae566bb288c34cf50d120b509146eee
2018-05-31Improve the ML based partition pruningHui Su
Add a neural net model that uses the same features as the existing linear model. Make the pruning decision based on both the linear and the neural net model. It provides more accurate predictions, and may improve compression and/or encoding speed. This only affects speed 0. Coding gain: 0.37% on midres 0.34% on hdres 0.50% on jvet8b720p Encoding speed impact(average over locally tested 20 clips from midres and hdres): QP=20: down by 2.5%. QP=30: down by 3.9%. QP=40: donw by 4.5%. QP=50: up by 5.2%. Change-Id: I402ec799745ad3b74abf0789fa5e124fe64e704d

2018-05-28vp9-realtime: Move frame dropper to after scene detection.Marco Paniconi
Move frame dropper to after scene detection and noise estimation. Scene detection and noise estimation operate on source data and update metrics along sequence, so they should be moved before the frame dropper. Also we don't want to drop on scene change, as the scene detection and (possible) re-encode step will be missed. Change-Id: I3d9e16d785bd5ace6707db2abce77ddc110bfef4
