2014-10-28vp9_denoiser_sse2: refactor the code.JackyChen
Combined vp9_denoiser_8xM_sse2 and vp9_denoiser_4xM_sse2 into one function vp9_denoiser_NxM_sse2_small and passed the bitexact testing. Changed the name of the function vp9_denoiser_64_32_16xM_sse2 to vp9_denoiser_NxM_sse2_big. Change-Id: Ib22478df585994dd347ebae04202c0b701e7f451
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
2014-10-27Use zero motion vector in choose_partitioningJingning Han
The zero motion vector was effectively used in the subsampled pixel based variance calculation. This commit makes it directly use zero mv to generate prediction. Change-Id: Ica83dc843e9f8da2f89c3ef451e50f16214c0def

2014-10-27Add a new control of golden frame boost in CBR modeYaowu Xu
0 means that golden boost is off, and uses average frame target rate, a non-zero number means the percentage of boost over average frame bitrate is given initially to golden frames in CBR mode. Change-Id: If4334fe2cc424b65ae0cce27f71b5561bf1e577d

2014-10-23Move frame re-sizing into the recode loopAdrian Grange
The point at which frames are scaled to their coded dimensions is moved into the re-code loop. This is in preparation for a further patch that will add logic into the re-code loop to reduce the coded frame size if the encoder is struggling to hit the target data rate at the native frame size.

2014-10-23Enable dual arf with constant q.Paul Wilkins
Add second level arf Q adjustment when using dual arfs in constant Q mode. Previously in constant Q mode enabling dual arf hurt by ~5% but with this change the average benefit is ~1-1.5% with some mid range data points up ~10%. Note however that it still hurts on some clips including some very low motion show content. Change-Id: I5b7789a2f42a6127d9e801cc010c20a7113bdd9b

This patch allocated frame contexts outside VP9_COMMON. This allows multiple threads to share the same copy of frame contexts, and reduces the overhead. It also guarantees the correct update of these contexts during bitstream packing. This patch doesn't change encoding result. Change-Id: Ic181a2460b891d1d587278a6d02d8057b9dbd353
