2010-12-13remove unused temporal preproc codeJohn Koleszar
This code is unused, as the current preproc implementation uses the same spatial filter that postproc uses. Change-Id: Ia06d5664917d67283f279e2480016bebed602ea7

Changed the end of block computation to use pmaxw. Removed additional pushing and popping of registers that was not needed. Change-Id: I08cb9b424513cd8a2c7ad8cea53b4e2adc66ef98
2010-12-09fix uninitialized read in encode breakoutJohn Koleszar
Change I3430820 performed an uninitialized read when encode_breakout == 0, since the sum and sse wouldn't be set: if(x->encode_breakout) VARIANCE_INVOKE(..., get16x16var)(..., &sum, &sse); if (cpi->active_map_enabled && x->active_ptr[0] == 0) { ... } else if (sse < x->encode_breakout) Change-Id: I915eb76d1227b4b6d1137a0dedf2c143860098a2
2010-12-09Correct q_low and q_high limits for the recode loopPaul Wilkins
Corrected the initial Q range limits for the recode loop to reflect the current allowed range for the frame. In experimental work on constrained quality this bug was causing unnecessary recodes. Change-Id: I7e256fbfa681293b0223fe21ec329933d76c229f

2010-12-06adjust RDMULT for UV plane in quantization RDOYaowu Xu
This patch adds a weighting factor on RDMULT for UV blocks. The change has an overall gain about 0.5% based on ssim, between 0.1 and 0.2% by psnr numbers. Change-Id: I97781b077ce3bb7e34241b03268491917e8d1d72

2010-12-04Merge "Change to inter_minq table."Paul Wilkins
2010-12-04Change to inter_minq table.Paul Wilkins
The inter_minq table controls the range of quantizers available for a particular frame in two pass relative to a max Q value. The changes reduces the range somewhat. The effect of this was a small increase (0.3% average) in psnr for the test set but it should also help encode speed somewhat for higher quality modes as it will reduce the number of iterations in the recode loop. The change damps the range of quantizers available locally within a section of a clip and should therefore help keep quality more uniform. If there is systematic overshoot or undershoot the range can shift gradually to accommodate. However, there is some increased risk of overshoot or undershoot against the target bit rate in VBR mode and this risk will be more pronounced for short clips.

2010-12-03Improve MV prediction accuracy to achieve performance gainYunqing Wang
Add vp8_mv_pred() to better predict starting MV for NEWMV mode in vp8_rd_pick_inter_mode(). Set different search ranges according to MV prediction accuracy, which improves encoder performance without hurting the quality. Also, as Yaowu suggested, using diamond search result as full search starting point and therefore adjusting(reducing) full search range helps the performance.

2010-12-01Set refresh_alt_ref_frame on keyframe encode.Fritz Koenig
On a keyframe alt ref and golden are refreshed. The flag was not being set and so on the frame after a keyframe, motion search would occur on the alt ref frame. This is not necessary because the alt ref frame identical to the last frame in this scenario. Handle corner case where a forward alt-ref frame is put directly after a keyframe.

2010-11-17vp8_set_maps: remove hard-coded width/heightJohn Koleszar

This function was never called in a context expecting a return value, the return value was always a constant, and the !CONFIG_MULTITHREAD path didn't have a return statement, which caused a compiler warning.

2010-11-15Bad cost tables used in ARNR filtering.Paul Wilkins
The use of incorrect mv costing tables in the ARNR sub-pel filtering code led to corruption of the altref buffer in some cases, particularly at low data rates. The average gain from this fix is about 0.3% but there are a few extreme cases where nasty and visible artifacts manifested and for these few data points the improvement is > 10%.

2010-11-11make rdmult adaptive for intra in quantizer RDOYaowu Xu
This intends to correct the tendency that VP8 aggressively favors rate on intra coded frames. Experiments tested different numbers in [0, 1] and found 9/16 overall provided about 2-4% gains for all-intra coded clips based on vpx-ssim metric. The impact on regular encoded clips is much smaller but positive overall. Overall impact on psnr is also positive even though very small. Change-Id: If808553aaaa87fdd44691f9787820ac9856d9f8a
2010-11-11quantizer: fix assertion in fast quantizer pathJohn Koleszar
The fast quantizer assembly code has not been updated to match the new exact quantizer, which was made the default in commit 6adbe09. Specifically, they are not aware of the potential for the coefficient to be scaled, which results in the quantized result exceeding the range of the DCT. This patch restores the previous behavior of using the non-shifted coefficients when in the fast quantizer code path, but unfortunately requires rebuilding the tables when switching between the two.
