libvpx only emits: VPX_IMG_FMT_{I420,I422,I440,I444,I42016,I42216,I44016,I44416} and additionally supports YV12 as input. interleaved yuv, rgb and alpha formats are unused. Change-Id: Ie2ab1099e950c6e696f475d46882f5c47a174042

2018-03-27vp9-svc: Add logic to enable for constrained framedrop.Marco Paniconi
Add the logic for the constrained framdrop mode for SVC. Add test case in datarate unittests. Also lower target bitrates in the tests to better test frame dropper. Change-Id: I8ee1b8cb56d835c233ad1fbe0fc1456cb2e7291f
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

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.

2018-02-09Reland "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.

2017-11-13New content type to improve grain retention.paulwilkins
For new VP9 only content type adjust the rate distortion and ARF filter based on the relative spatial variance of the source and reconstruction. In regards to the RD loop the method favors modes where the reconstruction variance is similar to the source variance. However it is currently only applied to regions where the source variance is quite low. For very low variance blocks it applies a further bias against intra coding and large prediction block sizes (the later in particular limit the usefulness of the loop filter). The final part of this change is to lower the strength of the ARF filter for blocks where the source has very low spatial variance, to encourage some low amplitude texture or noise to pass through the filter. This change improves the retention of film grain and fine noise / texture in spatially flat regions, but as expected causes a significant drop in PSNR on many clips. This is to be expected because similar but misaligned noise or texture will give a lower PSNR than a flat noise free reconstruction. However, it is worth noting that most clips show a strong gain in FAST SSIM. The features are enabled on the vpxenc command line by setting --tune-content=film. VPX_ENCODER_ABI_VERSION bumped for this change and cvbr. Change-Id: I26a4e4edfa3dc5cacead82fa701fe7a9118ccd0a
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.

2017-04-24Make 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
2017-02-13The 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
