2014-11-04Merge "Refactor sub-pixel motion search unit"Jingning Han
2014-11-04Skip ref frame mode search conditioned on predicted mv residualsJingning Han
This commit makes the RTC coding mode to conditionally skip the reference frame mode search, when the predicted motion vector of the current reference frame gives more than two times sum of absolute difference compared to that of other reference frames. It reduces the runtim by 1% - 4% for speed -5 and -6. The average compression performance is improved by about 0.1% in both settings. It is of particular benefit to light change scenarios. The compression performance of test clip mmmovingvga.y4m is improved by 6.39% and 15.69% at high bit rates for speed -5 and -6, respectively.

2014-10-28Merge "Add a new control of golden frame boost in CBR mode"Yaowu Xu
2014-10-28Allow update of golden refernce buffer in CBR modeYaowu Xu
This commit changes to allow the usage of golden reference frame in VP9 CBR mode to improve quality. VP9 supports potentially up to 8 reference buffers, it has reference buffers available for this purpose. This was not possible in VP8 as golden and alt-ref buffers were used for temporal scalability purpose in CBR mode in WebRTC. For frames that update golden frame, there can be a quality boost. The amount of allowed bitrate boost can be controlled via parameter rc_max_inter_bitrate_pct. The inital value of the boost ratior is currently based on over_shoot_pct. Further experiments will work out the adaption of this boost value. Change-Id: I0c5f010c8fd8b7b598f69779c1b30e5b2ac30a4d
2014-10-28Relax maximum Q for extreme overshoot.Paul Wilkins
Added code to relax the active maximum Q in response to extreme local overshoot to reduce bandwidth peaks. The impact is small in metrics terms, but it this helps reduce bandwidth spikes and overall overshoot in a number of clips in our tests sets (especially the YT test set). In particular this should help prevent very big spikes where a clip is mainly easy but has a short hard section. In such a case a choice of maximum Q for the clip as a whole may allow us to hit the overall target rate but give some extreme spikes. The chunked encoding in YT mitigates this problem but it can show up where a longer clip is coded as a single chunk. Change-Id: I213d09950ccb8489d10adf00fda1e53235b39203
