2013-02-27Faster vp9_short_fdct8x8.Christian Duvivier
Scalar path is about 1.4x faster (4% overall encoder speedup). SSE2 path is about 7x faster (13% overall encoder speedup). Change-Id: I7e85d8225a914a74c61ea370210414696560094d
2013-02-27Code cleanup.Dmitry Kovalev
Fixing code style, using array lookup instead of switch statements for forward hybrid transforms (in the same way as for their inverses). Consistent usage of ROUND_POWER_OF_TWO macro in appropriate places. Change-Id: I0d3822ae11f928905fdbfbe4158f91d97c71015f

2013-02-27Remove unused vp9_copy32xnJohn Koleszar
This function was part of an optimization used in VP8 that required caching two macroblocks. This is unused in VP9, and might not survive refactoring to support superblocks, so removing it for now. Change-Id: I744e585206ccc1ef9a402665c33863fc9fb46f0d

2013-02-27Merge "Combined motion compensation with scaled predictors" into experimentalJohn Koleszar
2013-02-27Use ref_frame_map vice active_ref_idx on the encoderJohn Koleszar
This patch makes the encoder's use of ref_frame_map and active_ref_idx consistent with the decoder. ref_frame_map[] maps a reference buffer index to its actual location in the yv12_fb array, since many references may share an underlying buffer. active_ref_idx[] mirrors cpi->{lst,gld,alt}_fb_idx, holding the active references in each slot. This also fixes a bug in setup_buffer_inter() where the incorrect reference was used to populate the scaling factors. Change-Id: Id3728f6d77cffcd27c248903bf51f9c3e594287e
2013-02-27Test upscaling as well as downscalingJohn Koleszar
Fixes a bug in vp9_set_internal_size() that prevented returning to the unscaled state. Updated the ResizeInternalTest to scale both down and up. Added a check that all frames are within 2.5% of the quality of the initial keyframe. Change-Id: I3b7ef17cdac144ed05b9148dce6badfa75cff5c8
2013-02-27Use 256-byte aligned filter tablesJohn Koleszar
This avoids duplicating all the filters twice. Includes fixups to the convolve routines and associated tests to make this work. Change-Id: I922f86021594e55072ddb63b42b2313605db6e00
2013-02-27Combined motion compensation with scaled predictorsJohn Koleszar
This patch extends the previous support for using references of a different resolution in ZEROMV mode to all inter prediction modes. Subpixel based best-mv scoring is disabled when the reference frame differs in resolution from the current frame. Change-Id: Id4dc3e5e6692de98d9857fd56bfad3ac57e944ac
2013-02-27Set scale factors consistently for SPLITMVJohn Koleszar
This commit updates the 4x4 prediction to consistently use the build_2x1_inter_predictor() method. That function is updated to calculate the scale offset, rather than relying on the caller to calculate it. In the case that the 2x1 prediction can not be used, the scale offset is recalculated for each 1x1 block. The idea here is that the offsets are calculated before each call to vp9_build_scaled_inter_predictor(). Change-Id: I0ac3343dd54e2846efa3c4195fcd328b709ca04d

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.

2013-02-26Optimize vp9_dc_only_idct_add_c functionYunqing Wang
Wrote SSE2 version of vp9_dc_only_idct_add_c function. In order to improve performance, clipped the absolute diff values to [0, 255]. This allowed us to keep the additions/subtractions in 8 bits. Test showed an over 2% decoder performance increase. Change-Id: Ie1a236d23d207e4ffcd1fc9f3d77462a9c7fe09d

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.

2013-02-26Improve 32x32 forward dctYaowu Xu
The commit improves the 32x32 forward dct implementation: 1. change to use same constants and rounding as other forward dcts 2. select rounding to specifically minimize the roundtrip error, which improved average 19/block to .77/block using 100000 random input. Test showed a small but consistent gain on all test sets, about .15% Change-Id: If0afd6a71880a522f60c1c234be0462092c2eb53
