2013-12-19Using single struct to represent scale factors.Dmitry Kovalev
Moving back to scale_factors struct. We don't need anymore x_offset_q4 and y_offset_q4 because both values are calculated locally inside vp9_scale_mv function. Change-Id: I78a2122ba253c428a14558bda0e78ece738d2b5b
2013-12-19Call set_scaled_offsets() just before scale_mv() call.Dmitry Kovalev
Before mv scaling it is required to calculate x_offset_q4/y_offset_q4 by calling set_scaled_offsets(). Now offset configuration can not be missed because it happens just before scale_mv(). Change-Id: I7dd1a85b85811a6cc67c46c9b01e6ccbbb06ce3a
2013-11-25Use separate inter predictors for enc/decJingning Han
The decoder will construct inter predictor using lazy border extension, while the encoder, going with multiple runs of motion search in the rate- distortion optimization loop for each block, does border extension at frame level. This commit makes separate the inter predictors for encoder and decoder, respectively. Change-Id: Ieca2fecba3a7201a6d64ef9f219e5d91e50559c3

2013-10-22Improve scale_factors structYunqing Wang
The ref's scale_factors are set at frame level, and then copied for each partition block. Since the struct members are mostly constant, this patch separated the constant and non-constant members, and reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain.

2013-07-18Merge scale_factors and scale_factors_uv.Ronald S. Bultje
This prevents a duplicate memcpy of a 128-byte struct every time set_scale_factors() is called (which is a lot), thus leading to a decrease from 3.7 MB to 1.85 MB of struct copying per 64x64 block RD/partition loop. Overall, this decreases encoding time of the first 50 frames of bus @ 1500kbps (speed 0) from 1min5.9 to 1min4.9, i.e. about a 1.5% overall speedup. We can likely get more gains by removing the copy of the other struct (and replacing it with an indexing) as well. Change-Id: I3dceb7e79f71e6fe911b11cc994cf89a869dde7a

2013-05-16Initial version of alpha channel supportJohn Koleszar
This is a mostly-working implementation of an extra channel in the bitstream. Configure with --enable-alpha to test. Notable TODOs: - Add extra channel to all mismatch tests, PSNR, SSIM, etc - Configurable subsampling - Variable number of planes (currently always uses all 4) - Loop filtering - Per-plane lossless quantizer - ARNR support This implementation just uses the same contents as the Y channel for the A channel, due to lack of content and general pain in playing back 4 channel content. A later patch will use the actual alpha channel passed in from outside the codec. Change-Id: Ibf81f023b1c570bd84b3064e9b4b8ae52e087592

2013-04-18Removing rounding from UV MV calculationJohn Koleszar
Consider the previous behavior for the MV 1 3/8 (11/8 pel). In the existing code, the fractional part of the MV is considered separately, and rounded is applied, giving a result of 6/8. Rounding is not required in this case, as we're increasing the precision from a q3 to a q4, and the correct value 11/16 can be represented exactly. Slight gain observed (+.033 average on derf) Change-Id: I320e160e8b12f1dd66aa0ce7966b5088870fe9f8
2013-04-18make buid_inter_predictors block size agnostic (luma)John Koleszar
This commit converts the luma versions of vp9_build_inter_predictors_sb to use a common function. Update the convolution functions to support block sizes larger than 16x16, and add a foreach_predicted_block walker. Next step will be to calculate the UV motion vector and implement SBUV, then fold in vp9_build_inter16x16_predictors_mb and SPLITMV. At the 16x16, 32x32, and 64x64 levels implemented in this commit, each plane is predicted with only a single call to vp9_build_inter_predictor. This is not yet called for SPLITMV. If the notion of SPLITMV/I8X8/I4X4 goes away, then the prediction block walker can go away, since we'll always predict the whole bsize in a single step. Implemented using a block walker at this stage for SPLITMV, as a 4x4 "prediction block size" within the BLOCK_SIZE_MB16X16 macroblock. It would also support other rectangular sizes too, if the blocks smaller than 16x16 remain implemented as a SPLITMV-like thing. Just using 4x4 for now. There's also a potential to combine with the foreach_transformed_block walker if the logic for calculating the size of the subsampled transform is made more straightforward, perhaps as a consequence of supporing smaller macroblocks than 16x16. Will watch what happens there. Change-Id: Iddd9973398542216601b630c628b9b7fdee33fe2
2013-04-18Make the use of pred buffers consistent in MB/SBJingning Han
Use in-place buffers (dst of MACROBLOCKD) for macroblock prediction. This makes the macroblock buffer handling consistent with those of superblock. Remove predictor buffer MACROBLOCKD. Change-Id: Id1bcd898961097b1e6230c10f0130753a59fc6df
2013-04-16Optimize the scaling calculationYunqing Wang
In decoder, the scaling calculation, such as (mv * x_num / x_den), is fairly time-consuming. In this patch, we check if the scaling happens or not at frame level, and then decide which function to call to skip scaling calculation when no scaling is needed. Tests showed a 3% decoder performance gain. Change-Id: I270901dd0331048e50368cfd51ce273dd82b8733
2013-04-12Enable inter predictor for rectangular block sizeJingning Han
Combine superblock inter predictors into a unified function that allows configurable block width and height. The inter predictions of block sizes smaller than 16x16 are handled differently. To be continued on merging them later. Change-Id: I14075959dd5e221f00c205c99ca35c1c31ef728e
2013-04-11WIP: removing predictor buffer usage from decoderScott LaVarnway
This patch will use the dest buffer instead of the predictor buffer. This will allow us in future commits to remove the extra mem copy that occurs in the dequant functions when eob == 0. We should also be able to remove extra params that are passed into the dequant functions. Change-Id: I7241bc1ab797a430418b1f3a95b5476db7455f6a
2013-03-27Removing redundant function arguments.Dmitry Kovalev

2013-02-26Spatial resamping of ZEROMV predictorsJohn Koleszar
This patch allows coding frames using references of different resolution, in ZEROMV mode. For compound prediction, either reference may be scaled. To test, I use the resize_test and enable WRITE_RECON_BUFFER in vp9_onyxd_if.c. It's also useful to apply this patch to test/i420_video_source.h: --- a/test/i420_video_source.h +++ b/test/i420_video_source.h @@ -93,6 +93,7 @@ class I420VideoSource : public VideoSource { virtual void FillFrame() { // Read a frame from input_file. + if (frame_ != 3) if (fread(img_->img_data, raw_sz_, 1, input_file_) == 0) { limit_ = frame_; } This forces the frame that the resolution changes on to be coded with no motion, only scaling, and improves the quality of the result.

2013-02-26Refactor inter recon functions to support scalingJohn Koleszar
Ensure that all inter prediction goes through a common code path that takes scaling into account. Removes a bunch of duplicate 1st/2nd predictor code. Also introduces a 16x8 mode for 8x8 MVs, similar to the 8x4 trick we were doing before. This has an unexpected effect with EIGHTTAP_SMOOTH, so it's disabled in that case for now. Change-Id: Ia053e823a8bc616a988a0af30452e1e75a739cba
2013-02-05Convert subpixel filters to use convolve frameworkJohn Koleszar
Update the code to call the new convolution functions to do subpixel prediction rather than the existing functions. Remove the old C and assembly code, since it is unused. This causes a 50% performance reduction on the decoder, but that will be resolved when the asm for the new functions is available. There is no consensus for whether 6-tap or 2-tap predictors will be supported in the final codec, so these filters are implemented in terms of the 8-tap code, so that quality testing of these modes can continue. Implementing the lower complexity algorithms is a simple exercise, should it be necessary. This code produces slightly better results in the EIGHTTAP_SMOOTH case, since the filter is now applied in only one direction when the subpel motion is only in one direction. Like the previous code, the filtering is skipped entirely on full-pel MVs. This combination seems to give the best quality gains, but this may be indicative of a bug in the encoder's filter selection, since the encoder could achieve the result of skipping the filtering on full-pel by selecting one of the other filters. This should be revisited. Quality gains on derf positive on almost all clips. The only clip that seemed to be hurt at all datarates was football (-0.115% PSNR average, -0.587% min). Overall averages 0.375% PSNR, 0.347% SSIM. Change-Id: I7d469716091b1d89b4b08adde5863999319d69ff
