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.

2018-02-09Reland "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.

2017-11-08CVBR 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.

2014-11-10Vidyo: Support for one-pass rc-enabled SVC encoderDeb Mukherjee
Adds support for one-pass rc-enabled SVC encoder with callbacks for getting per-layer packets. - the callback function registration is implemented as an encoder control function. - if the callback function is not registered, the old way of aggregating packets with superframe will take effect. - one more control function “VP9E_GET_SVC_LAYER_ID” has been implemented to get the temporal/spatial id from the encoder within the callback. This can be used to get the ids to put on RTP packet. Change-Id: I1a90e00135dde65da128b758e6c00b57299a111a

2013-09-06Support a constant quality mode in VP9Deb Mukherjee
Adds a new end-usage option for constant quality encoding in vpx. This first version implemented for VP9, encodes all regular inter frames using the quality specified in the --cq-level= option, while encoding all key frames and golden/altref frames at a quality better than that. The current performance on derfraw300 is +0.910% up from bitrate control, but achieved without multiple recode loops per frame. The decision for qp for each altref/golden/key frame will be improved in subsequent patches based on better use of stats from the first pass. Further, the qp for regular inter frames may also be varied around the provided cq-level. Change-Id: I6c4a2a68563679d60e0616ebcb11698578615fb3

2012-06-28Add lossless compression mode.Hui Su
This commit adds lossless compression capability to the experimental branch. The lossless experiment can be enabled using --enable-lossless in configure. When the experiment is enabled, the encoder will use lossless compression mode by command line option --lossless, and the decoder automatically recognizes a losslessly encoded clip and decodes accordingly. To achieve the lossless coding, this commit has changed the following: 1. To encode at lossless mode, encoder forces the use of unit quantizer, i.e, Q 0, where effective quantization is 1. Encoder also disables the usage of 8x8 transform and allows only 4x4 transform; 2. At Q 0, the first order 4x4 DCT/IDCT have been switched over to a pair of forward and inverse Walsh-Hadamard Transform (http://goo.gl/EIsfy), with proper scaling applied to match the range of the original 4x4 DCT/IDCT pair; 3. At Q 0, the second order remains to use the previous walsh-hadamard transform pair. However, to maintain the reversibility in second order transform at Q 0, scaling down is applied to first order DC coefficients prior to forward transform, and scaling up is applied to the second order output prior to quantization. Symmetric upscaling and downscaling are added around inverse second order transform; 4. At lossless mode, encoder also disables a number of minor features to ensure no loss is introduced, these features includes: a. Trellis quantization optimization b. Loop filtering c. Aggressive zero-binning, rounding and zero-bin boosting d. Mode based zero-bin boosting Lossless coding test was performed on all clips within the derf set, to verify that the commit has achieved lossless compression for all clips. The average compression ratio is around 2.57 to 1. (http://goo.gl/dEShs) Change-Id: Ia3aba7dd09df40dd590f93b9aba134defbc64e34
