2014-04-02Rate ctrl changes to track target bitrates closerDeb Mukherjee
Turns off the DISABLE_RC_LONG_TERM_MEM macro and makes other changes in the way the bits are updated, to make 2-pass rate control track target bitrates closer. Change-Id: I5f3be4b11c2908e6a9a9a1dd4fcf4e65531c44d8

2014-04-02Make frame level quantization change a parameterJingning Han
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
2014-04-02Add 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).

2014-04-01Speed setting correction to max q estimate.Paul Wilkins
Use a crude correction factor to correct for lower compression efficiency at higher encode speeds when estimating the max Q for the clip. Change-Id: I5ae377647f4adf5e91d700a8791fb3b8f70efc73
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

2014-02-25Adds variance based fixed size partitioningDeb Mukherjee
Adds a method for determining a fixed size partition based on variance of a 64x64 SB. This method is added to rtc speed 6. Also fixes a bug in rtc_use_partition() and includes some refactoring related to partitioning search, and some cosmetics. Currently compared to speed 5, the coding efficiency of speed 6 is -19% and that of speed 7 is -55%, in cbr mode. Change-Id: I057e04125a8b765906bb7d4bf7a36d1e575de7c6

2014-02-11Removes active_worst_quality feedbackDeb Mukherjee
Removes certain cases of feedback of active_worst_quality, and removes it from the RATE_CONTROL structure. Now active worst quality is expected to be computed locally in the q picking function during the encode. Making temporal filter strength depend on avg_frame_qindex rather than on active_worst_quality actually improves performance esp. for yt. derf: +0.038% yt: +0.359% Change-Id: I1fe5a343034b55af9322289165321f00ac0827b1

Fixes some of the parameters for 1-pass non-cbr mode. Also includes some cleanups, inlcuding refactoring of the recode_loop options. Results on derfraw300 improve by about 5-6%, so that the one-pass mode is now 13% below the 2-pass mode in speed 0. Change-Id: I844cc2638694c7574f3be00d41d60b23dc1016f0
2014-02-06Layer based rate control for CBR mode.Marco Paniconi
This patch adds a buffer-based rate control for temporal layers, under CBR mode. Added vpx_temporal_scalable_patters.c encoder for testing temporal layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns). Updated datarate unittest with tests for temporal layer rate-targeting. Change-Id: I8900a854288b9354d9c697cfeb0243a9fd6790b1

2014-02-05One-pass rate control cleanups/fixes/refactoringDeb Mukherjee
Inlcudes a number cleanups: 1. Moves the one-pass pre-encode parameter setting functions to vp9_ratectrl.c 2. Deprecates per_frame_bandwidth in RATE_CONTROL structure 3. Removes target_bandwidth in cpi structure since it is not used. 4. Various renaming of functions There is no bit-stream change in 2-pass, one-pass cbr and one-pass vbr modes.

2014-02-04One-pass rate control fixes and cleanupsDeb Mukherjee
Fixes rate control partially in one-pass non-cbr case to achieve a bitrate close to the one desired. Previous version was way off at the high bitrate end. Also includes several one-pass rate control cleanups and refactoring. On derfraw300, one-pass encoding is now 19% off from two-pass speed 0 encoding, down from 35%.
