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

2017-04-24Make 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

2016-10-19vp8: Add control for gf boost for 1 pass cbr.Marco
Control already exists for vp9, adding it to vp8. Usage is only when error_resilient is off. Added a datarate unittest for non-zero boost. Change-Id: I4296055ebe2f4f048e8210f344531f6486ac9e35
2016-08-24Add --alt-ref-aq=<int> optionYury Gitman

Encoder will create the adaptive quantization map on the basis of lookahead buffers similarity which is the estimate of the future motion compensation performance.

2015-09-25vp9/10: improve support for render_width/height.Ronald S. Bultje
In the decoder, map this to the output variable vpx_image_t.r_w/h. This is intended as an improved version of VP9D_GET_DISPLAY_SIZE, which doesn't work with parallel frame decoding. In the encoder, map this to a codec control func (VP9E_SET_RENDER_SIZE) that takes a w/h pair argument in a int[2] (identical to VP9D_GET_DISPLAY_SIZE). Also add render_size to the encoder_param_get_to_decoder unit test. See issue 1030. Change-Id: I12124c13602d832bf4c44090db08c1009c94c7e8
2015-09-17Add SVC codec control to set frame flags and buffer indices.Marco
Add SVC codec control to set the frame flags and buffer indices for each spatial layer of the current (super)frame to be encoded. This allows the application to set (and change on the fly) the reference frame configuration for spatial layers. Added an example layer pattern (spatial and temporal layers) in vp9_spatial_svc_encoder for the bypass_mode using new control. Change-Id: I05f941897cae13fb9275b939d11f93941cb73bee
2015-09-16Add support for color-range.Ronald S. Bultje
In decoder, export (eventually) into vpx_image_t.range field. In encoder, use oxcf->color_range to set it (same way as for color_space). See issue 1059. Change-Id: Ieabbb2a785fa58cc4044bd54eee66f328f3906ce

2015-07-06Expose params min-gf-interval/max-gf-intervalDebargha Mukherjee
Adds two new vp9 parameters --min-gf-interval and --max-gf-interval to enable testing based on frequency of alt-ref frames. Also adds a unit-test to test enforcement of min-gf-interval. For both these parameters the default value is 0, which indicates they are picked by the encoder, based on resolution and framerate considerations. If they are greater than zero, the specified parameter is honored. (Additional note by paulwilkins) Note that there is a slight oddity in that key frames are also GFs and considered part of GF only group. However they are treated as not being part of an arf group because for arf groups the previous GF is assumed to be the terminal or overlay frame for the previous group.

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
