2014-04-04Set up early RD cost check for NEWMV in non-RD mode decision flowJingning Han
This commit estimates the motion vector rate cost right after full pixel motion search. It combines this and the mode cost and compares the corresponding rate-distortion cost. If it is already above the current best one, skip the rest sub-pixel motion search and modeling process. For pedestrian_area 1080p at 4000 kpbs, the speed -5 runtime goes down from 39425 ms -> 38399 ms. Change-Id: If4cd7119fd6c266798d5cf1d19d19ab425e52a26
2014-04-02Adjust key frame quantization index for rtc codingJingning Han
This commit slightly increases the bit allocation for key frame. This improves speed -5 coding performance by 2.77% with aq-mode=0 and by 2.78% with aq-mode=3. Change-Id: Iaa3e777f80b9706306606af06e89852bac146659

2014-04-02Set min_block_size for aq_mode=3 to 8x8.Marco Paniconi
For real-time mode under cbr, this increases the gain (5-10%) for speed 5 (none/little change for 6), on vc-clips. Change-Id: I9b38beeb3c820de22c43a0ba53a9456168dd24ba

Parameterize the frame level quantization index used in non-RD coding flow with cbr. Change-Id: I79cfbd9c32c0d0fc33ad720d2180432e910baf7a
2014-04-02Adjust rate allocation in non-RD coding modeJingning Han
This commit reduces the frequency of frames using finer quantizer in non-RD coding flow, and slightly tune up the quantizer resolution when used. It provides 1.7% compression gains in speed -5 at no speed difference. Change-Id: I430249a51260a841a0402666e5ec1566e4f7d5a6
2014-04-02Revert "Changing webmenc to use libwebm"Paul Wilkins
Temporary revert. Problems with conflicting definitions of type off_t in MSVC builds that need resolving. c:\Program Files (x86)\ Microsoft Visual Studio 9.0\VC\include\wchar.h(479) : "error C2371: 'off_t' : redefinition; different basic types c:\on2experimental\libvpx\tools_common.h(26) : see declaration of 'off_t'" This reverts commit 92a4c591122fa406a1d7aed834a5283a86d9758a.

2014-04-02Add speed feature for recode tolerance.Paul Wilkins
The new tolerance is a little higher than before (especially for kf/gf/arf) so this change gives an encode speed up for some clips up for speeds 0-2. Change-Id: I63f7d6c9cc11c7f58742f41e250dcd3eab1741eb

2014-04-01Remove the q division by 3 for first frame.Marco Paniconi
This code/setting was actually not used (since speed features were not set on first frame, until a recent change) and should be removed. In CBR mode, the q value for the first frame can be controlled by setting the target size via the parameters rc_buf_initial_sz (and max_intra_size_pct).

2014-04-01Make last frame source available in current frame encodingYunqing Wang
While encoding a frame, its last frame source can be used to give acurate motion information. This patch prevents last frame to be overwritten so that it is available during current frame encoding. The last source is scaled when it is necessary. cpi->Last_Source points to the last source frame. Change-Id: I0e1ef5e9e1d2badf9d0c7a1a44a7ed5b24c09425

2014-03-31Apply finer quantizer to partition search frames in non-RD flowJingning Han
This commit optimizes the bit allocation for the non-RD coding flow. It applies slightly better quantizer to the frames, where all blocks run a non-RD partition search. Such frames typically have better rate-distortion trade off, thus improving the reconstruction quality for next few frames reference at reasonably low increment in rate cost. The coding performance for rtc set at speed -5 with error-resilient tuned on and rate control set as cbr is improved by 19.58%. It improved the coding speed by about 10% for a portion of local test clips. Change-Id: I9d56696cd4359dc8136ca10aff10fff05aaa2686

2014-03-28[BITSTREAM]Fix the scaling calculationYaowu Xu
For very large size video image, the scaling calculation may need use value beyond the range of int. This commit upgrade the value to 64bit to make sure the calculation do not wrap around INT_MAX. The change corrected the decoder behavior. The bug affects only very large resolution video because the scaling calculation was sufficient for image size smaller than 2^13. This resolves issue: https://code.google.com/p/webm/issues/detail?id=750 Change-Id: I2d2ed303ca6482f31f819f3c07d6d3e98ef3adc5
2014-03-28Adjust rt speed steps.Yaowu Xu
This commit adjusted the speed steps in rt mode to make the steps more evenly spaced on speed and quality, specifically: 1. Merged 3 and 4 into one single step 3 and removed confilicting features. 2. Move 8, 7, 6, 5 to be 7, 6, 5, 4 repsectively. Change-Id: I38d56d61531f3561d772aef953c411c8fb38c063
