2018-05-14VP9: Add speed 9 for subpel search.Jerome Jiang
Set subpel search stop to 2 when motion vector is non zero. 10% speedup on 1 and 2 threads on Samsung Galaxy S8+. Change-Id: I7323bb913000229cf60a37495bf88bcc51d0ac96

2018-03-26vp9-svc: Allow for setting frame drop thresholds per layer.Marco Paniconi
Add encoder control to set the frame drop thresholds per spatial layer, and add a frame drop mode: 0 = per-layer drop, and 1 = constrained drop mode (a drop on a given layer forces drops to all upper layers). Default is mode 0 (per-layer dropping). Implementation for mode 1 will come in subsequent change. If the control is not used, then the spatial layer frame drop thresholds (water mark) are all equal and set to the value given by the encoder config (oxcf->drop_frames_water_mark). Bump up the ABI version. Change-Id: Id038d4181b86fa98b3d44d026f96d5f344d81629
2018-03-20VP9 SVC: Add control to disable inter layer prediction.Jerome Jiang
Add VP9E_SET_SVC_INTER_LAYER_PRED to disable inter layer (spatial) prediction. 0: prediction on 1: prediction off for all frames 2: prediction off for non key frames Bump up ABI version. Change-Id: I5ab2a96b47e6bef202290fe726bed5f99bd4951f
2018-03-20vp9-svc: Improve frame dropper for spatial layers.Marco Paniconi
SVC frame dropper: modify the logic to allow for individual spatial layers to drop. This removes the constraint that all upper spatial layers must drop when a given spatial layer drops. Add a flag to the pkt to indicate whether a spatial layer is encoded or dropped. This is needed for applications that enable this feature (frame dropping for SVC). For a current spatial layer, if its previous spatial layer is dropped, then disable certain features for that layer: inter-layer prediction, base_mv, partition_reuse, copy partition. Also add the constraint to never drop a spatial layer if its base layer is a key frame. Updates to sample encoder (vp9_spatial_svc_encoder) and the SVC datarate unittests to properly handle frame dropping. Bump up ABI version. Change-Id: I7d14ccf67b8d014a7abfce5ba3989fc623e94067
2018-03-15vp9-svc: Frame dropper for SVC.Marco Paniconi
If a given spatial layer decides to drop, due to the buffer/overshoot conditions for that layer, then drop that current spatial layer and all spatial layers above. In the current implementation the svc frame counter (and hence the pattern for the non-flexible SVC case) are updated on frame drops. Also add last spatial layer encoded to the pkt. This is useful for RTC applications that enable frame dropping for SVC. Update to the SVC datarate tests: enabled frame dropper on all SVC datarate tests, and made a fix to properly set the temporal_layer_id, which works now even on frame drops.

2018-03-14vp9-svc: Bugfix to dyanmic enabling/disabling of layers.Marco Paniconi
Fix a bug when middle and top spatial layer are skip encoded (disabled) and then re-enabled again, during the sequence. Issue is that pending_frame_count in the packing may be incremented on middle layer, even though that layer is skipped (not encoded and hence zero size). Fix is to add size check. Modified existing unitest to reproduce the issue. Change-Id: I86d806a112d468e06b04fbf7c46ae07db9e0ad93

2018-02-09Reland "Add ROI support for VP9."Jerome Jiang
Extended ROI struct suitable for VP9. ROI input from user is passed into internal struct and applied on every frame (except key frame). Enabled usage of all 4 VP9 segment features (delta_qp, delta_lf, skip, ref_frame) via the ROI map input. Made changes to nonrd_pickmode for the ref_frame feature. Only works for realtime speed >= 5. AQ_MODE needs to be turned off for ROI to take effect. Change example in the sample encoder: vpx_temporal_svc_encoder.c to be suitable for VP9. Add datarate test. Bump up ABI version.

2018-01-11vp9: Skip encoding of enhancement layers on the fly.Marco
For SVC: if an enhancement layer (spatial_layer > 0) has 0 bandwidth, skip/drop the encoding of the layer. This allows the application to dynamically disable higher layers for SVC. Add flag to signal the skip encoding, this is needed to modify the packing of the superframe when the top layer is skipped/dropped. Also moved some updates (current_video_frame counter and the last_avg_frame_bandwidth) to the postencode_update_drop_frame(). Added datarate unittest for dynamically going from 3 to 2 and then back to 3 spatial layers. Change-Id: Idaccdb4aca25ba1d822ed1b4219f94e2e8640d43

2017-11-08CVBR command line option.paulwilkins
Added command line control of Corpus VBR. The new corpus vbr mode is a variant of standard VBR (end-usage=0) where the complexity distribution mid point is passed in rather than calculated for a specific clip or chunk. The new variant is enabled by setting a new command line parameter --corpus-complexity to a zero value. Omitting this parameter or setting it to 0 will cause the codec to use standard vbr mode. The correct value for a given corpus needs to be derived experimentally using a training set such that the average rate for the corpus is close to the target value. For example our using our low res test set with upper and lower vbr limits of 50%-150% and a corpus complexity value of 650 gives a similar average data rate across the set to using standard vbr. However, with the corpus mode easier clips will be allocated fewer bits and harder clips more bits rather than having the same rate target for all.

2017-09-14VP9 level targeting: add a new AUTO modeHui Su
In the new AUTO mode, restrict the minimum alt-ref interval and max column tiles adaptively based on picture size, while not applying any rate control constraints. This mode aims to produce encodings that fit into levels corresponding to the source picture size, with minimum compression quality lost. However, the bitstream is not guaranteed to be level compatible, e.g., the average bitrate may exceed level limit. BUG=b/64451920 Change-Id: I02080b169cbbef4ab2e08c0df4697ce894aad83c
2017-08-16Prevent parameters that can cause invalid ARF groups.paulwilkins
Having a very low "lag_in_frames" value could cause the encoder to create incorrect / corrupt ARF groups including displayed frames that update the ARF buffer and false overlay frames that are coded at low rate but are not actually overlays of a real ARF frame. This is linked to a reported unit test "slow down" where the chosen parameters (lag of 3 frames) gave rise to such "broken" ARF group(s).

2017-06-07vp9 level targeting: more strict constraint on min_gf_intervalhui su

2017-04-24Make the row based multi-threaded encoder deterministicYunqing Wang
This patch followed allow_exhaustive_searches feature modification and continued to modify the encoder to achieve the determinism in the row based multi-threaded encoding. While row-mt = 1 and using multiple threads, the adaptive feature in encoder was disabled, which gave BDRate gain(at speed 1, -0.6% ~ -0.7%; at speed 2, -0.46% ~ -0.59%), but some encoder speed losses(7% ~ 10% at speed 1 and 3% ~ 6% at speed 2). These speed losses were acceptable considering the speed gains obtained from row-mt. Change-Id: I60d87a25346ebc487a864b57d559f560b7e398bb
2017-04-06VP9 motion vector unit testYunqing Wang
To prevent the motion vector out of range bug, added a motion vector unit test in VP9. In the 4k video encoding, always forced to use extreme motion vectors and also encouraged to use INTER modes. In the decoding, checked if the motion vector was valid, and also checked the encoder/decoder mismatch. The tests showed that this unit test could reveal the issue we saw before.

2017-02-27vp9: Rename new_mt to row_mtVignesh Venkatasubramanian
new_mt is a very generic name that will get obsolete soon enough. Since this is exposed as a codec control, renaming it to row_mt to signify row level paralellism. Also renaming the ETHREAD_BIT_MATCH codec control to ROW_MT_BIT_EXACT. Change-Id: Ic7872d78bb3b12fb4cf92ba028ec8e08eb3a9558
2017-02-15Row based multi-threading of encoding stageRanjit Kumar Tulabandu
(Yunqing Wang) This patch implements the row-based multi-threading within tiles in the encoding pass, and substantially speeds up the multi-threaded encoder in VP9. Speed tests at speed 1 on STDHD(using 4 tiles) set show that the average speedups of the encoding pass(second pass in the 2-pass encoding) is 7% while using 2 threads, 16% while using 4 threads, 85% while using 8 threads, and 116% while using 16 threads.

2017-02-13The bitstream bit match test in multi-threaded encoderYunqing Wang
While the new-mt mode is enabled(namely, allowing to use row-based multi-threading in encoder), several speed features that adaptively adjust encoding parameters during encoding would cause mismatch between single-thread encoded bitstream and multi-thread encoded bitstream. This patch provides a set_control API to disable these features, so that the bit match bitstream is obtained in the unit test. Change-Id: Ie9868bafdfe196296d1dd29e0dca517f6a9a4d60
