x86-64 passes arguments in registers. There is no need to push them to the stack before using them. This fixes 15acc84f where ebx was not getting preserved on x86. Change-Id: I1214b5f818a0201f75ab6ad7d5c6f448e09b16c2

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%.

When the first pts equaled 0 ivfenc was incorrectly increasing the pts by 1. I changed the pts and last pts to be signed. I also set the default value of last pts to -1. Change-Id: I30bcec5af9b16d93fa9e3abbea7764b133e9cd73

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

The fast quantizer assembly code has not been updated to match the new exact quantizer, which was made the default in commit 6adbe090. 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.

- Used three probability approach for temporal context as follows: P0 - probability of no change if both above and left not changed P1 - probability of no change if one of above and left has changed P2 - probability of no change if both above and left have changed In addition, a 1 bit/frame has been used to decide whether to use temporal context or to encode directly. The cost of using both the schemes is calculated ahead and the temporal_update flag is set if the cost of using temporal context is lower than encoding the segment ids directly. This approach has given around 20% reduction in cost of bits needed to encode segmentation ids. Change-Id: I44a5509599eded215ae5be9554314280d3d35405

VBR rate control can become very noisy for the last few frames. If there are a few bits to spare or a small overshoot then the target rate and hence quantizer may start to fluctuate wildly. This patch prevents further adjustment of the active Q limits for the last few frames. Patch also removes some redundant variables and makes one small bug fix.

Small changes to the default zero bin and rounding tables. Though the tables are currently the same for the Y1 and Y2 cases I have left them as separate tables in case we want to tune this later. There is now some adjustment of the zbin based on the prediction mode. Previously this was restricted to an adjustment for gf/arf 0,0 MV. The exact quantizer now marginal outperforms and is the default. The overall average gain is about 0.5% Change-Id: I5e4353f3d5326dde4e86823684b236a1e9ea7f47

The check '(user_data_end - partition < partition_size)' must be evaluated as a signed comparison, but because partition_size was unsigned, the LHS was promoted to unsigned, causing an incorrect result on 32-bit. Instead, check the upper and lower bounds of the segment separately. Change-Id: I6266aba7fd7de084268712a3d2a81424ead7aa06

Change Ice204e86 identified a problem with bitrate undershoot due to low precision in the timestamps passed to the library. This patch takes a different approach by calculating the duration of this frame and passing it to the library, rather than using a fixed duration and letting the library average it out with higher precision timestamps. This part of the fix only applies to vpxenc. This patch also attempts to fix the problem for generic applications that may have made the same mistake vpxenc did. Instead of calculating this frame's duration by the difference of this frame's and the last frame's start time, we use the end times instead. This allows the framerate calculation to scavenge "unclaimed" time from the last frame. For instance: start | end | calculated duration ======+=======+==================== 0ms 33ms 33ms 33ms 66ms 33ms 66ms 99ms 33ms 100ms 133ms 34ms Change-Id: I92be4b3518e0bd530e97f90e69e75330a4c413fc
